Question

I’m using GDB to step through the code.

The problem is my code has functions from external files. Is there a way on stepping through inner functions?

like this:

    int main 
    { 
    string a ="AAA"; 
    DoString(a);
    }

Is there a way on stepping through execution of DoString with GDB?

Answer 1

You mention assembly in the tags, so I assume the function is not in C. Just use si (short for stepi) GDB command to step one machine instruction at a time. See the manual.
