Does memory allocated in a function still stay allocated after the function returns?

Question

For the code below: (1) \"main\" calls a function \"f1\". (2) function \"f1\" does some number crunching; creates an array of \"char\" with mal

Answer 1

1. Yes, it's still in the heap. However, you are confusing about the concept of process. Unless you create another process (using fork on *nix), it's still the same process.

2. It's a good habit to free the memory when it's not used. But if the program terminates normally, the allocated memory is freed by the system.

3. Like this:

   int main () {
       char *fData = f1 (...);
       //...
       free(fData);
       //...
   }
