Thread: variable for array ?

hi all~

i remembered one-dimentional array requires const as argument when it was established but now i can pass variable to it ? i update Dev-C++ not long ago i wonder whethere it was exception of Dev-C++ compiler, my code is right below:

Code:

int main()
{
    int n = 10;
    int arr[n];    // No error occured !!!
    return 0;
}

any ideas ?
