Hello,
I try to solve problem 1209 with allocating memory, but i receive compilation error.

---------------------------------------------------------


Code example:
---------------------------------------------------------
#include <stdio.h>
#include <malloc.h>

int main()
{
        int N;
    scanf("%d", &N);
    int *AA = (int *)malloc(N*sizeof(int));
        ... ... ...
        free(AA);
        return 0;
}
---------------------------------------------------------
What the matter ?

Thank you for answers.

This is correct code for C++, not for C, because when using C compiler, only forward var declarations are permited

{
int N = 0;
int* AA = NULL;
// ...
AA = (int*)malloc(..);

// etc.
}

I receive this kind of errors again...

It is very strange.
