That is usually a function of the debugger.
Some debuggers have a trace option that will print out
the line of code being executed or, more commonly, selected
lines of code each time they are executed. (Printing every
line of a non-trivial program generates huge amounts of
output very quickly!)

But be aware that debuggers will slow your code down
massively - often by 100 times or more. Its not really
a practical option for anything non-trivial. And if
its trivial why would you need it - just insert a few
print statements!
