Freeing a 2d array in C

C

I'm studing C programming for quiet few months now but every time I get stack in one problem. What happens if we want to free a 2d array. I know that I should use a for loop to free each row and column but I don't know if I do it right.

So this is my example.

I have an array wich is declared with int

    int c = 1000;
int array[c][2];

and here's the free function:

for (int i = 0; i < c; i++) 
	free(array[i]);
	free(array);

When I try to compile it with gcc I get the following errors:

Quote:

C:\Users\George\Desktop>gcc -std=c99 per2.c -o per2.exe
per2.c: In function 'main':
per2.c:86:2: warning: implicit declaration of function 'free' [-Wimplicit-functi

free(array[i]);

ee' [enabled by default]
per2.c:87:2: warning: incompatible implicit declaration of built-in function 'fr

free(array);

Is there any problem and what is the standart formula to free a 2c array (static and dynamic)
