Reverse an Array In-Place

Code

#include <stdio.h>

void reverse_array(int arr[], int n) {
    // Your logic here
    int temp;
    for(int i=0;i<n/2;i++){ // n/2: stop at array's mid point
        temp = arr[n-i-1]; // use temp to store higher index data
        arr[n-i-1] = arr[i]; // move lower index data to higher index location
        arr[i] = temp; // move higher index data to lower index location
    }
}

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;
}
