Reverse an Array Using Only Pointers

Code

#include <stdio.h>

void reverse_array(int *ptr, int n) {
    // Your logic here
    for(int nArr = 0; nArr < n/2; nArr++)
    {
        *(ptr+nArr) ^= *(ptr+n-1-nArr);
        *(ptr+n-1-nArr) ^= *(ptr+nArr) ;
        *(ptr+nArr) ^= *(ptr+n-1-nArr);
    }
}

int main() {
    int n;
    scanf("%d", &n);

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

    reverse_array(arr, n);

    for (int i = 0; i < n; i++) {
        printf("%d", arr[i]);
        if(i < n-1){
            printf(" ");
        }
    }

    return 0;
}
