|None of the algorithms I used (
set_intersection) use or have any need for the C runtime library. There is no distinct C++ runtime library. The only CRT function used is the one I introduced:
strcmp (ignoring the functions I used to write the output to the console). None of what you say need be true. In general using STL will decrease your working time and will have not have a detrimental effect on the footprint of your EXE. Most of your fears are superstition.
