Updated code is #include "stdafx.h" #include int main() { using namespace std; cout <> b; int e; e = b*10; int l; l = e/100; int a; a = e+b; int d; d = l+e; int s; s = 2*(d-a); int m; m = b+l; cout << b << e << l << a << d << s << m; return 0; } you are missing main() function. Updated code is

#include “stdafx.h”
#include
int main()
{
using namespace std;

cout <> b;

int e;
e = b*10;

int l;
l = e/100;

int a;
a = e+b;

int d;
d = l+e;

int s;
s = 2*(d-a);

int m;
m = b+l;

cout << b << e << l << a << d << s << m;

return 0;

}
