Function in C++ - Cyborg Coding

A function in C++ is a self-contained block of code that can be called from other parts of a program. Functions are a way to organize and reuse code, allowing you to break down a complex program into smaller, more manageable parts. Functions can take input parameters, perform a set of operations, and return an output value.

Functions are defined by their return type, name, and input parameters (also known as arguments or parameters). For example, here is the syntax for a function called "add" that takes two integers as input and returns their sum:

int add(int a, int b) {

    return a + b;

}

Functions can be called by their name, followed by a set of parentheses that contain the input parameters. For example, the following line of code calls the "add" function and assigns the result to the variable "result":

int result = add(2, 3);

C++ also has a special function called "main", which is the starting point of every C++ program. When a C++ program is executed, the code inside the main function is executed first.

Functions are useful in many ways, they can help to group logically related operations together, they can help to make the code more readable, they can help to make the code more reusable, they can help to make the code more modular, they can help to make the code more testable, and they can help to improve the overall structure of the program.
