While we generate control flow graph from source code it contains many loops like while, if, for etc... So when we generate path for testing what should we need to do to remove a loop? For example: in 2 3 4 5 2 3 4 5 2 3 4 5 2 3 4 5 ........ 6 7 8, there is a loop from 2-5. While generating path how we can handle this situation?

There is no obvious answer, since the number of iterations of a loop is an undecidable problem. Most coverage criteria will lead you to unfold the loop 0/1 times. Most tools do a little more. The "loop acceleration techniques" can help symbolic test case generators, by computing an approximation of the transitive closure of the loop.
