Modularity

C++ Functions

Functions are reusable blocks of code that perform a specific task. They help in organizing code, reducing redundancy, and improving readability.

BASIC ANATOMY

return_type function_name(parameters) {
    // code to execute
    return value;
}

REUSABILITY

Write once, use many times throughout your program.

ABSTRACTION

Hide complex logic behind a simple function call.

VOID FUNCTIONS

Functions that don't return any value use the void return type. Useful for printing or modifying global state.
