It's not about lines of code it's about the number and type of problems solved. I have spent days looking for a solution when all I needed to do was change a single constant. I have also written hundred of lines of code whole hog, been surprized that it compiled without errors, and shocked that it was bug free. Yet, I have no idea what was more usefull.
Spending a few months working on hard problems without a functional debugger can compleatly change how you aproach programming. But, so does finaly understanding how to use a debugger. Spending a few weeks reading other peoples code to document a working system was also an incredably valuable experence.
PS: The closest thing to a single nuber I can think of is "how many diffrent months of experence do you have?"
