Reverse an Array In-Place

Code

#include <stdio.h>

void reverse_array(int arr[], int n) {
    // Your logic here
    int *pStart; 
    int *pEnd; 
    pStart = arr; 
    pEnd = arr; 
    // printf(" *pstart %d \n", *pStart); 
    for (int i=0; i < n; i++){
        // printf(" *pend %d \n", *pEnd);
        ++pEnd; 
    }
     
    --pEnd; 
    // printf(" *pend %d \n", *pEnd);
    int temp = 0; 
    while (pEnd > pStart){
        temp = *pEnd; 
        *pEnd = *pStart; 
        *pStart = temp; 

        ++pStart; 
        --pEnd; 

    }
}

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;
}
