bookWhat is Function in C++?

Note
Definition

A function is a block of code designed to perform a specific task.

You've already seen this with the special main() function, which serves as the entry point of every program. However, you can also create your own functions to organize and reuse code efficiently.

main.cpp

main.cpp

copy
1234567891011121314
#include <iostream> // Function to add two numbers int add(int a, int b) { return a + b; } int main() { // Calling the `add` function int result = add(3, 4); std::cout << result << std::endl; }

The add() function is defined to take two numbers, add them together, and return the result. This function is then called inside the main() function, and the result is printed to the console.
