Which of the following statements are correct about the program below?

#include<stdio.h>
void main()
{
    int size, i;
    scanf("%d", &size);
    int arr[size];
    for(i=1; i<=size; i++)
    {
        scanf("%d", arr[i]);
        printf("%d", arr[i]);
    }
}

A. The code is erroneous since the statement declaring array is invalid.

B. The code is erroneous since the subscript for array used in for loop is in the range 1 to size.

C. The code is correct and runs successfully.

D. The code is erroneous since the values of array are getting scanned through the loop.

E. None of these

Answer: Option A

Solution(By Examveda Team)

The statement int arr[size]; produces an error, because we cannot initialize the size of array dynamically. Constant expression is required here.
Example: int arr[10];
One more point is there, that is, usually declaration is not allowed after calling any function in a current block of code. In the given program the declaration int arr[10]; is placed after a function call scanf().
