Want to hire freelance C++ developers on your own? Here are the skills you must look for while hiring a freelance C++ developer

Hiring freelance C++ developers might be a complicated task for you if you are a non-technical manager. C++ is a widely-used programming language in the computer programming field, especially in graphics design, games development (because of its multiplayer support over a network), and developing database software. But, even if you belong to technical field, hiring freelance C++ developers among thousands of freelance developers is a challenging task for anyone. So, Ultragenius is here to assist you while hiring the top talented freelance developers on your own. 

The following skills you must ensure while hiring a freelance C++ developer –¬†

Steadfast knowledge of C++ library, containers, and algorithms

The C++ Standard Library (STL) is a collection of all C++ classes, data structures, algorithms, templates that are designed in C++. C++ STL can make your code more reusable, fast-working, and extensible. STL provides four types of components, namely, algorithms, functions, iterators, and containers. The freelance C++ developers must know about Containers, Algorithms, Iterators, Container Adopters, Associative Containers, and Sequential Containers. 

Experience writing code in C++

The freelance C++ developer must have experience writing code in C++. C++, like Java and Python, has various functions, algorithms, and data structures that the freelance C++ developer must be aware of. With the knowledge of its standard library, the C++ developer can code faster while maintaining the simplicity of code. Check if the freelance C++ developer can code well in C++ and knows about its input-output stream (cout, cin), the difference between “\n” and endl, flush stream, use of cerr, etc.

Knowledge of Template coding

Templates are the powerful in-built feature of C++ which allows a programmer to write a generic algorithm that works with all kinds of data types and eliminates the requirement of writing different classes, functions, or some other code for different data types like integer, float, or string. It is also called Generic Programming.  

Firm understanding of Object Oriented Programming Concepts

C++ is widely used as an Object Oriented Programming language. OOP helps to emulate real world entities. For example, if you want to design a messaging app, you have to first design a message class that contain all the information about sender,  message content, receiver, and message identity all inside a single class. The freelance C++ developer must know about Encapsulation, Inheritance, Polymorphism, and Abstraction. Check whether the freelance C++ developer knows about early or static binding, dynamic binding or late binding, various types of inheritance, etc. 

Experienced working with code versioning tools like Git, SVN, TFS

Freelance C++ developers must have a very good knowledge of version control systems, like Git, SVN, TFS, and Mercurial. Mostly, developers use Git for their work. It is the version control system that helps the team in collaborating and organizing your code, maintain the frequent changes that occur in the code. Git helps in reviewing the old codes and compares them with the newly updated code, pulling the code from their repository, and managing the commit history.

Along with this, the freelance C++ developer must know how to use add, push, pull, and commit commands, how to do  branching, and merging as it allows developers to work independently on the code.

Excellent understanding of testing frameworks and tools

Rising quick-deployment needs during the development phase, testing has become a very important skill for developers to know. Check the freelance C++ developers’ knowledge about Jest, Enzyme, Mocha, Chai, AVA, and Tape for unit testing.For end-to-end testing, check their knowledge about Selenium, Webdriver, Cucumber.js, Nightwatch.js, Cypress, and Puppeteer. For integration testing, ensure that the¬†freelance C++ developers know about Karma.¬†

Firm understanding of OS internals and knowledge of Linux

The freelance C++ developers write the code on Linux environment as it is an open source platform embedded with lots of C++ libraries and there are a lot of projects written in C++ for Linux/Unix operating system. The freelance C++ developers must have firm understanding of setting up the environment, compiling, running, and debugging the code,  and installing different types of libraries. 

Knowledge of Front-end frameworks and libraries

Familiarity with at least one of the front-end frameworks is a must for any developer like React.js or Angular.js. These front-end frameworks are greatly required in today’s market. React is popular for its faster development of Single Page Applications while Angular uses interpolation, dependency injection, and eliminates coding mistakes by using the strongly typed Typescript that resolves many challenges faced by the developers.

Experience working with SQL and NoSQL databases

The freelance C++ developers must know working with SQL and NoSQL databases.. The freelance C++ developer must be familiar with the fundamental concepts of DBMS like data integrity, data access control, automatic rollback, restart and recovery. The developers must know DDL, DML, DCL, TCL, and DQL commands.  Check if the freelance C++ developer is well-versed with  about Normalization, E-R Model, ORM Mapping, and Joins.

Knowledge of HTML and CSS

HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are the two must-know core technologies for any developer. You must hire a freelance C++ developer who has worked with these technologies in depth. Knowledge of Flexbox and CSS Grid, in addition to Bootstrap, Semantic and Structural Styling, and Foundation is a must to an Android developer freelancer. Along with this, the developer should be well-versed in Javascript libraries especially jQuery and CSS grid systems. 

Familiarity with Javascript language

Javascript is most widely used language in developing dynamic web applications and helps a developer integrate back-end with the front-end easily. The freelance C++¬†developer¬†must be clear with the fundamental concepts of Javascript language. ECMAScript 6 (or ES6) is the current version of ECMAScript and is widely used by developers up to a large extent. The¬†freelance C++ developers must be familiar with these ES6 skills ‚Äst

  • Arrow functions
  • Blocked scope constructors let and const
  • Advanced object literals
  • Template literals
  • Multi-line strings
  • Modules
  • Module loaders
  • Binary and octal literals
  • Reflect API
  • Proxies
  • Classes
  • Destructuring assignment
Familiarity with web markup and UI, UX Concepts

While developing a C++ application, the freelance C++ developer must be familiar with HTML, CSS, and Javascript. The developer must have a firm understanding of element positioning, displaying the elements, and making components interactive, semantic markup, and other related UX Concepts so they can design the product with the best quality. The developer must be experienced in developing visual effects in presentational markup. For, example РHow the heading appears, making text larger and putting weight to it, and giving which color to it, and which markup can include captions, bind columns, and row headings to table cells. 

Experienced with Software Configuration Management (SCM)

The developers must know about Software Configuration Management. Software Configuration Management (SCM) is the process of identifying, tracking, and controlling the changes in the software. The SCM activities are important for a freelance C++ developer to know. SCM helps developers to track and handle the products and its different versions. It identifies and controls the software configuration, hardware, and tools that are involved in the software development process.

Proficient in writing optimized and readable code

You must hire the freelance C++ developers based on their ability to write clean and optimized code that is understandable by all the team members, and is scalable.

C++ is robust language used in developing desktop and mobile applications. It is very fast because of which it is used in developing game engines and variety of games. C++ provides different paradigms of programming like procedural, object-oriented, imperative, and declarative. But recruiting the best freelance C++ developers is not an easy task when a large no. of C++ freelancers are competing to grab the job opportunities.  

Top Interview Questions to ask while hiring a freelance C++ developer

  • The reference variable once assigned cannot be reassigned with different values while the pointer variable acts independently of assigning values and can be reassigned pointing to different variables.
  • A pointer variable can be assigned NULL values while a reference variable cannot.
  • A reference variable is compulsorily initialized at the time of declaration while it is not necessary to initialize the pointer variable at the time of declaration.
  • The pointer requires an indirection operator to access the value while the reference value can be accessed directly.
  • The reference variable is a type of alias for the existing variable while the pointer variable stores the address of a variable.

A friend function is a function which is specified outside a class but can access the private, protected, and public members of that class. Friend functions are only used for specific purpose and is avoided normally. 

The main characteristics of a friend function is - 

  • Friend functions are outside the scope of the class in which they are declared.
  • As the friend function is outside the scope of a class, it is invoked without creating a object of that class.
  • A friend function cannot directly access the private members of a class, it needs to use an¬†object name with dot operator¬†to access them.
  • Friend functions take objects as arguments.

 

Function Overloading provides more than one definition of any function. The difference can be in the number of parameters and the type of parameters. For example, 

  • double add(int a, float b)
  • double add (float a, int b)
  • double add (double a, double b, double c)

Function Overriding means the object created at run-time decides which function has to be invoked if the reference is of parent class. 

 

The four pillars of Object-Oriented Programming is -

  • Encapsulation -¬†Encapsulation is the ability of a class to hide its data variables and avoids its direct access. Encapsulation is achieved by invoking getter()¬†and¬†setter()¬†functions on an object to access a data variable.
  • Inheritance -¬†Inheritance is the mechanism of a class to extend the functionality of another class. It provides the advantage of code reusability to the¬†freelance C++ developers.
  • Abstraction -¬†Abstraction is the process of hiding the implementation details of any class and showing only the necessary or required details to a user.¬†Abstract classes¬†and Interfaces best uses the concept of Abstraction.
  • Polymorphism -¬†Polymorphism is the ability of a fucntion to take many forms. Polymorphism is of two types -¬†Compile-time Polymorphism¬†and¬†Run-time Polymorphism.¬†¬†In Compile-time Polymorphism, the function call is decided at the compile-time only. Among the functions with the same name, the invocation is decided based on¬† number of parameters and type of parameters. It implements¬†Function Overloading.¬†¬†In Run-Time Polymorphism, the object of the child class decides which method to invoke at the run-time. It implements¬†Function Overriding.¬†

using namespace std is the scope in which class names, function names, and variable names are defined. C++ contains the in-built classes, libraries, and functions that the freelance C++ developers use in designing applications.

A virtual function is a member of the base class which is overridden in the derived class. The virtual function in base class needs to be overridden in the child class. Virtual functions implement Run-time Polymorphism. In the derived class, the object created at the run-time decides whether the virtual function of base class is invoked or the overridden function of derived class is invoked using base class pointer.

Run-time polymorphism can be achieved without using virtual functions by type-casting the base class pointer to the derived class pointer and then calling the function. 

For example, 

class Base{

void func(){}

};

class Derived : public Base{

void func(){

}

};

int main(){

Base* ob = new Derived;

Derived* d = static_cast<Derived*>(ob);

d->func();

  • A structure groups various data types which are called by the same name while a class binds the data variables and member functions inside a single structure.¬†
  • Classes support inheritance while structures don't support inheritance.
  • A structure occupies memory on the¬†

Functions that are declared as static in the base class cannot be overridden in the derived class because they are not affected by the object creation. However, static functions can be overloaded 

Destructors are the member functions in a class used to delete objects when they go out of class scope, function ends, program ends, and the delete keyword is called to deallocate the memory of an object. The destructors are different from normal member functions because neither they take arguments nor they return anything. For example, 

class Test{

int a,b;

cin>>a>>b;

public Test(int a, int b){

cout<<"Inside Constructors\n";

this.a = a;

this.b = b;

}

void show(){

cout<<a<<" " <<b<<endl;

}

~Test(){

cout<<"Inside Destructor\n";

}

int main(){

Test obj(10,20);

obj.show();

return 0;

}

The output of the program is  - 

Inside Constructor

10 20 

Inside Destructor
