I wanted to compare two single string variable in my SC and if they were different, I wanted to add +1 to my int data "fights", let's say *X[1] = A, Y[1] = B, add +1 to **fights***.

```
    int N;
    char X;
    char Y;

    int fights = 0;

    1 <= N <= 100000;

    for (int i = 0; i < N; i++){
        cin >> X[i];
        cin >> Y[i];

        if (Y[i] != X[i]){
           fights += 1;
        }     
    }
    cout << fights;

    return 0;
}

```

However, it seems like the program is not detecting any differences when I input different letters and does not add +1 to ***fights***.
