The trick is that I want to give the user some options. After the conversion from yard to feet is done, I want to ask the user whether or not he/she wants to also convert from feet to yard. If the user says yes, then the script should be executed and the conversion from feet to yard done. But the user says no, the program should stop and exit out.

I need some ideas.
This sounds like homework. If it is, you should make an effort to write the script. If you then need help, post what you have written, and ask a more detailed question concerning your problem.

If it isn't homework, you should still make the effort.
