How to make program to check predefined answers with the ones that are entered and print the final result ?

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>

int main()
{
    char a,b;
    int x=1,correct=0,incorrect=0,unattempted=0;
    printf("Enter Answer for Q.%d: ",x);
    scanf("%c",&a);
    x++;

    switch(a)
    {
    case 'A':
        printf("Correct \n");
        correct++;
        break;
    case 'U':
        unattempted++;
        break;
    default:
        printf("Wrong \n");
        incorrect++;
        break;
    }
    printf("Enter Answer for Q.2:");
    scanf("%c",&b);
    x++;
    switch(b)
    {
    case 'A':
        printf("Correct \n");
        correct++;
        break;
    default:
        printf("Wrong \n");
        incorrect++;
        break;
    }
    printf("Correct = %d ; Incorrect = %d ; Unattempted = %d",correct,incorrect,unattempted);
    return 0;
}

Enter Answer for Q.1: A
Correct
Enter Answer for Q.2:Wrong
Correct = 1 ; Incorrect = 1 ; Unattempted = 0
Process returned 0 (0x0)   execution time : 2.281 s
