Answer 1

Replace

cin>> a,b;

with

cin >> a;
cin >> b;

Also try and improve your formatting, it took me awhile to understand what was wrong.

#include <iostream>
using namespace std;

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

cout<<"type in two numbers and let the second one bigger \n";
cin >> a;
cin >> b;

if (b > a) {
cout << "you're right\n";
}

if (a > b) {
cout <<"!!!you're wrong!!! \n";
}

c=a-b;
cout <<"b is "<< c <<" smaller than a";

return 0;
}

Answer 2

get it :)
thanks a lot
