Functions with Arguments with Return Values

Functions in C can also have parameters (arguments) and return values.

The return type specifies the type of value the function will return.

Here's the basic syntax for a function with arguments and a return value:
return_type functionName(parameter1_type parameter1_name, parameter2_type parameter2_name, ...);

Here's an example of a function with arguments that calculates and returns the sum of two integers:

#include <stdio.h>
// Function declaration
int addNumbers(int a, int b);
int main() {
// Function call
int result = addNumbers(5, 7);
// Output the result
printf("Sum: %d\n", result);
return 0;
}
// Function definition
int addNumbers(int a, int b) {
return a + b;
}

Output:
Sum: 12
