3. Functions

A function is a collection of code blocks with instructions inside, which is used for specific tasks. It is meant to be reused as per requirement, making the division of complex problems into smaller and manageable pieces. What is Function Overriding in C++? Function overriding is a concept of object-oriented programming which allows a derived class […]

Function overloading in C++ allows you to define multiple functions with the same name but different parameters. Function overloading is used to achieve polymorphism which is an important concept of object-oriented programming systems. Syntax for Overloaded Functions Consider the following two function declarations having the same name but different parameters − Example of Function Overloading In […]

The return statement in C++ is used to exit a function and to send a value back to the function’s caller which is optional depending on requirement. It plays a very important role in controlling the flow of a program and making sure that functions will provide results to other parts of the code. Syntax Below is […]

Recursion is a programming technique where a function calls itself over again and again with modified arguments until it reaches its base case, where the recursion stops. It breaks a problem down into smaller, more manageable sub-problems, recursion allows for elegant and better solutions to complex problems. Recursive Function A recursive function is a function […]

C++ multiple function parameters describe the ability of a function to accept more than one argument or can say functions with multiple parameters to perform operations using several inputs, this feature makes a function to execute more complex operations by working with multiple subset of data at once. Syntax In C++, you can define a […]

A function is a group of statements that together perform a task. Every C++ program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions. How you divide up your code among different functions is up to you, but […]
