Loop Trouble

***Edit** New error:

Code:

#include <iostream>
#include <cstring>
#include <windows.h>
#include <stdlib.h>
#include <time.h>
#include <mmsystem.h>
using namespace std;

int ans1int=0;
int ans2int=0;
int ans3int=1;
char ans1[4];
char ans2[4];
char f1[2];
char f2[2];
char m1[2];
char m2[2];
char f1f2[10];
char m1m2[10];
char f1m1[10];
char f1m2[10];
char f2m2[10];
char f2m1[10];

int main()
{
    while(ans3int==1){
        while(ans1int==0){
            cout<<"Fathers code - letter 1"<<endl;
            cin.getline(f1, 2);
            cout<<"Fathers code - letter 2"<<endl;
            cin.getline(f2, 2);
            strcat (f1f2, f1);
            strcat (f1f2, f2);
            cout<<"Your father is "<<f1f2<<" correct? [Yes/No]"<<endl;
            cin.getline(ans1, 4);
            if (strcmp(ans1, "Yes")==0 || strcmp(ans1, "yes")==0)
                ans1int=1;
        }

When I say no instead of yes, it gives me HhhH (or whatever I input), example: I say Hh the first time, then say no. So I go through again saying hH, and it should say hH back to me, but instead it says HhhH.

How do I clear a char?

Sounds like a case of not clearing the keyboard's buffer (You have leftover input from the keyboard that's still wanting to be read).

This FAQ article is mighty handy on the topic:
