[Dev-C++] Freeing of allocated memory

[Jan M. <jan...@vo...>]

Hello,

I would like to ask and clear the problem of freeing a memory previously
allocated.
I have got a program and this a simple example of something similar:

#include<stdlib.h>
#include<stdio.h>

void chng (int **in_a)
{
int *temp;

temp = malloc(sizeof(int));
*temp = 1;
*in_a = temp;

}

int main()
{
int *a;

chng(&a);

printf ("a = %d\n", a);
free (a);

return 0;
}

And I would like to know if this free (a);
at the end of main() frees also a temp pointer which is used in chng()
function.
It should to do this because it adress the same part of memory if I
understand it correctly.

If you notice any other problem with the thing above, plese tell me.

Thank you very much
