My issue

not working

My code

#include <stdio.h>

int main() {
    int arr[100] = {4, 5, 3, 10, 12, 18}; // Initial array
                     // Current size of the array
    int size=6;
    int newPosition = 5; // Index where you want to insert the new element
    int newElement = 7; // Element to be inserted

    // Shift elements to make space for the new element
    for(int i=size;i>i;i--){
        arr[i]=arr[i-1];
    }



    int newPosition= 5;
    int newElement= 7;// Insert the new element at the specified position
    arr[newPosition]=newElement;

    // Update the size of the array
    for(int i=0;i<=size;i++){
        printf("%d",arr[i]);
    }
    // Print the updated array




    return 0;
}
