Yes it is possible to convert the number into binary. Read the help on _itoa_s or if your compiler doesn't have it itoa.
Hope this helps.
CODE
#include <iostream>
using namespace std;
int main()
{
int x = 'R';
char buf[20];
_itoa_s( x, buf, 19, 2 );
cout << "The number " << x << " is binary: " << buf;
}
