50. Reverse an Array Using Only Pointers

#include <stdio.h>

void reverse_array(int *ptr, int n) {
    // Your logic here
    int *begin = ptr;
    int *end = ptr + (n - 1);
while(begin < end){
    int ram = *begin;
    *begin = *end;
    *end = ram;
    begin++;
    end--;
}


}

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;
