};

int main() {
    srand(time(NULL));
    char numaraDeposu[10000][6] = { "" };
    struct Otobusler buss[1000];

    scanf("%d", &bussNo);
    for (int i = 1; i <= bussNo; i++) {
        for (int j = 0; j < 4; j++) {
            numaraDeposu[i][j] = hex[rand() % 16];
        }
        for (int k = 4; k >= 0; k--) {
            int l = k + 2;
            numaraDeposu[i][l] = numaraDeposu[i][k];
        }
        numaraDeposu[i][0] = ogrNo[0];
        numaraDeposu[i][1] = ogrNo[1];
        strcpy(buss[i].bussHexNum[i], numaraDeposu[i]);
        buss[i].bussNumber = i;
        printf("%d-%s\n", buss[i].bussNumber, buss[i].bussHexNum[i]);
    }
    hexControlFonk(buss[1000]);
    printf("%s\n", buss[10].bussHexNum[10]);
}

void hexControlFonk(struct Otobusler buss[1000]) {
    for (int m = 1; m < bussNo; m++) {
        for (int n = 1; n < bussNo; n++) {
            if (strcmp(buss[m].bussHexNum[m], buss[n].bussHexNum[n]) == 0 && n != m) {
                printf("%d,", n);
            }
        }
    }
    printf("%s\n", buss[10].bussHexNum[10]);
}

I made a program which makes hexadecimal numbers for each buss. And they start with 34 (my school Number) it works fine but I can't use modified version of structure in hexControlFonk(). This function checks if any 2 hex codes are the same. But buss 10 in main and buss 10 in hexControlFonk isn't same. Need help.

Here are some important issues with your code (compiled list from comments).
As you have confirmed by now, fixing these also solves your problem.

  • Fix wrong prototype: void hexControlFonk(); -> void hexControlFonk(struct Otobusler buss[1000]);

  • Move type declaration needed for the correct prototype to before the prototype.

  • Comment by WhozCraig: Call the function correctly, with the array (effectively with a pointer to it); hexControlFonk(buss[1000]); ==> hexControlFonk(buss);`

  • Comment by Werner Henze: (covered by above) Do not call the function with a value read from behind the array, i.e. with an index from the allowed range 0...999, not 1000.
