Solution in C:-

#include <stdio.h>

#include <stdlib.h>

int main()

{

    int num, *arr, i;

    scanf("%d", &num);

    arr = (int*) malloc(num * sizeof(int));

    for(i = 0; i < num; i++) {

        scanf("%d", arr + i);

    }

    

    for(i = num-1; i>-1; i--)

        printf("%d ", *(arr + i));

    return 0;

}
