I get expected constant expression error in VS, but it runs on tutorialspoint web compiler?

#include <stdio.h>
#include <conio.h>

const int MAX = 3;

int main() {

    int var[] = { 10, 100, 200 };
    int i, *ptr[MAX];

    for (i = 0; i < MAX; i++) { 
        ptr[i] = &var[i]; /* assign the address of integer. */
        _getch();
    }

    for (i = 0; i < MAX; i++) {
        printf("Value of var[%d] = %d\n", i, *ptr[i]);
        _getch();
    }

    return 0;
}

The definition int *ptr[MAX]; where MAX is not a compile time constant expression is supported since C99 for automatic variables. Even defined as a const int MAX = 3, MAX is not considered a compile time constant in C. Your version of Visual Studio does not seem to support this syntax, but the online compiler at tutorialspoint does.
