Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    int temp = *mem;
    int i=1;
    for(i;i<(n-1);i++){
        temp ^= *(mem+i);
    }
   if(temp == *(mem+i)) return 1;
    return 0;
}

int main() {
    int n, arr[100];
    scanf("%d", &n);
    
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    int result = validate_checksum(arr, n);
    printf("%d", result);

    return 0;
}
