Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n)
{
    int XOR=0;
    for(int i=0; i<n-1; i++)
    {
       XOR = mem[i] ^ XOR;
    }

    if(XOR == mem[n-1])
        return 1;
    else 
        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);
}
