Reverse an Array Using Only Pointers

Code

#include <stdio.h>

void reverse_array(int *ptr, int n) {
    // Your logic here
    int l=0;
    int curr=0;
    int r=n;
    int temp;
    int last;
    while (l<r){
        temp=*ptr;
        curr=l;
        while (curr<r-1){
            ptr++;
            curr++;
        }
        last=*ptr;
        *ptr=temp;
        for (int i=0;i<(r-l-1);i++){
            ptr--;
        }
        *ptr=last;
        ptr++;
        r--;
        l++;
    }
}

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;
}
