header files

[koved]

i want to know what is the code written in header files.(how a functions works)
is that possible

for e.g.
i created my own version of sqrt function in .C
now i want to know the difference b/w my code and sqrt function code.
i want to check how efficiently i created it.

thnks

you can always look for your header files in your library folders. Look for the address in the "Options" or "Preferences" of your c++ compiler, or go to the folder you configured when setting it up.

Once you reached the folder, look for the library you intend to study. That should do it

You don't need sqrt source to compare your own implementation efficiency. Just run math.h sqrt in a loop - record total calculation time.
do the same thing with your sqrt - then compare execution times. Of course all conditions should be equal, that is - run experiment on same argument values and etc. Also you can compare calculation precision.
