Reverse an Array In-Place

Code

#include <stdio.h>

int *reverse_array(int arr[], int n) {
    // Your logic here
    int a;
   for(int i=n-1 ;i>=(n/2);i--){//4,3,2
    int temp =arr[(n-1)-i];//3
    arr[(n-1)-i] = arr[i]; //5,4,3
    arr[i]=temp;
   }
   return arr;
}

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;
}
