Question

I have a function:

char *make_text(void)
{       
        char txt[MAXLEN];
        //make something
        return txt;
}

Thats my main program:

int main(void)
{
        char *s = make_text();
        puts(s);
        getch();
        return 0;
}

puts(s) returns 0 and its nothing printed. Whats happened?

Answer 1

The memory you allocated in the make_text function got freed at the end of make_text. So you shouldn’t try to access it.

You could allocate the memory using malloc or calloc, so it doesn’t get freed automatically.
