To understand this better refer to the program code below.

C++ code.

#include <iostream>

using namespace std;

int multiply(int a, int b)

{

cout << a*b <<endl;

return 0;

}

int multiply(int a, int b, int c)

{

cout << a*b*c <<endl;

return 0;

}

int main()

{

//function with two arguments passed

multiply(3, 50);

//function with three arguments passed . It is different in number of arguments passed. Thus here function signature is different

multiply(4, 20, 10);
