how to declare a function in c++

Declaring a Function in C++

To declare a function in C++, follow these steps:

  1. Specify the Return Type: Start with the return type of the function. If the function does not return a value, use the keyword "void".

  2. Provide the Function Name: Next, specify the name of the function.

  3. Add Parameters (if any): If the function takes parameters, list the parameter types and names within parentheses.

  4. End with a Semicolon: End the function declaration with a semicolon.

Here's an example of a function declaration in C++:

int add(int a, int b);

In this example, the function is declared with the return type "int", the function name "add", and two integer parameters "a" and "b".
