Answer 1

Yes. Try this way...

int a;
cin >> a; //if incompatible input, cin fails.. So

if(cin.fail())
{
cout<<"error, invlid input";
exit(1);
}

Answer 2

I mean to add it just after cin as I mentioned. Not at last

Edit : Lugli

#include <iostream>
using namespace std;

int main()
{
int a;
int b = 6;

cin >> a;
if(cin.fail())
{
cout<<"error, invalid input";
exit(1);
}

if( a>b )
cout << "its greater than 6";
else if(a<b)
cout << "its smaller than 6";
else
cout<<"both equal";

return 0;
}
