Declaring a Function in C++
To declare a function in C++, follow these steps:
Specify the Return Type: Start with the return type of the function. If the function does not return a value, use the keyword "void".
Provide the Function Name: Next, specify the name of the function.
Add Parameters (if any): If the function takes parameters, list the parameter types and names within parentheses.
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".
