That is a C++ program and you are using C++ io (cout) so you should avoid using C io via getc().

If you really need to do that then

char c;
cin >> c;
 

Also

#include<iostre am.h>

Is the pre 1998 standardisation version of the header and may not be portable use

#include<iostream>
 
using namespace std;
