Reverse an Array Using Only Pointers

Code

#include <stdio.h>

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

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;
}
