Merging problem when calling same function twice with different parameters in C

Question

i have this piece of code:

void Win_Check(int mat[][MAX], int player, int x1, int y1) {
    int check, check2, check3, check4, check5, check6;
    check = HorizontalCheck(x1, y1, mat, -1);
    check2 = HorizontalCheck(x1, y1, mat, 0);
    check3 = VeritcalCheck(x1, y1, mat, -1);
    check4 = VeritcalCheck(x1, y1, mat, 0);
    check5 = DiagonalCheck(x1, y1, mat, -1);
    check6 = DiagonalCheck(x1, y1, mat, 0);
    if (check == 1 || check3 == 1 || check5 == 1)
        Win_Event(-1, x1, y1, mat);
    if (check2 == 1 || check4 == 1 || check6 == 1)
        Win_Event(0, x1, y1, mat);
    Tie_Check(x1, y1, mat, player);
}

the problem im having is specifically with the lines where i assign check variables to the function DiagonalCheck that function looks like this:

int DiagonalCheck(int x1, int y1, int mat[][MAX], int sign) {
    int initialX = 0, initialY, i, j = initialX, CurrentX, Count;
    for (j; j < x1;) {
        Count = 0;
        for (CurrentX = j, initialY = 0; initialY <= y1 - 1; initialY++, CurrentX++) {
            if (mat[initialY][CurrentX] == sign)
                Count++;
            if (mat[initialY][CurrentX] != sign)
                Count = 0;
            if (Count == 4)
                return 1;
            printf("%d\n", Count);
        }
        j++;
    }
}

for all of the other functions they work as intended and check things for different parameters but specifically with this function the input from both functions kind of merges. i know solutions to this in other languages but never encouterd it in C before and would like some help in fixing the problem. thanks in advance.

Answer 1

i finally figured it out what i did was just have 2 signs be entered into the same function and then run the same code inside of the function for each sign and returning 0 at the end of the second outer loop.
