I was given this project as a part of my school assignment, please note that I have very limited knowledge of the language, and my teacher won't allow using anything other than what is used in the following code (Crappy 12th grade curriculum:yawn:)...
Here is my complete code, its in premature stage, and I haven't considered the seating constraints yet,, on compiling it gives DECLARATION TERMINATED INCORRECTLY ERROR!!,i am planning to run this and correct errors as they come, but its not going to run untill that error is removed... Please help!.:icon_eek:
