Reverse an Array In-Place

Code

#include <stdio.h>
#include <stdint.h>

void reverse_array(int arr[], int n) {
    // Your logic here
    int *l = arr;
    int *r = arr + n -1;
    while(l < r){
        *l= *l + *r;
        *r = *l - *r;
        *l = *l - *r;

        l++;
        r--;
    }

}

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;
}
