Any help it 's welcome.
/************************************************** ********/
#include <iostream>

#include "math.h"
using namespace std;

int add_number(int a, int b, int c)
{
cout << "enter a" << endl;
cin >>a;
cout << "enter b "<< endl;
cin >> b;
c = a + b;
return (a, b, c);
}

int main ()
{
signed int a, b, c;
