Checksum Validation

Code

#include <stdio.h>
#include <stdint.h>

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

    printf("%d",calculator_checksum(arr, n));
    return 0;
}
