Yes. You haven't read the FAQ which answers your question which has been
asked and answered frequently.
:>if i compile the following c program using the compiler options: gcc -g

You just need one more option: -lm, which links in the math-library.
This library defines sqrt(), pow() and many other mathematical functions.
Haha!
