Reverse an Array Using Only Pointers

Code

#include <stdio.h>

void reverse_array(int *ptr, int n) {
    // Your logic here
    int *ptr2 = ptr+(n-1);
    int temp=0;
    for(int i=0; i<n/2; i++){
        temp = *ptr;
        *ptr = *ptr2;
        *ptr2 = temp;
        ptr++; ptr2--;
    }

}

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;
}
