Q: declare four variables of string types bu using c string library,then apply and practice on all string standard functions such as : strlen,strcat,strcpy,strcmp,...
You may not. Contrary to popular belief, we are not sitting behind the keyboard waiting for questions so we stop what we are doing to provide answers for free. If you want the solution, then post it to the jobs section and be willing to pay money for it.
Good Luck!
