Question

I’,m probably doing some incredibly stupid mistake, but i cannot find it, it is simple that:

int main()
{

typedef struct drzemka typ;
struct drzemka {     
int strukcje;
};
typ *d;
d->strukcje = 1;
}

and it is not working

Answer 1

Right now your pointer is not set to a valid piece of memory. You need to allocated this memory for the struct:

#include <stdlib.h>
/* ... */
typ *d = malloc(sizeof(typ));

As with any memory you allocate, remember to free it after you’re done:

free(d);
