when i input zero the program will reset how can i stop that from happenning, and when i compile my program the (Avg cost/lb) is giving me (-1.#J) what is this crap!! Also how can i improve this program to be more bullet.

Well, run is 0, i is 0; what do you expect 0/0 to print?
i think it should be error
oh yea i get it now how can i change that
Only if you have a very shaky grasp on numbers.Quote:

What do you want to change? My suggestion is not to print the receipt, or whatever that is, all the time; or check to see if i is 0 and if so don't print that line.Quote:

Also, fflush(stdin) is undefined behavior, so there's no telling what happens after that.
well, i have to print that line because its an assigment
i thnink i should change it to scanf("%s") to read the string. also maybe if i put a loop on avg it may work saying if its zero to ask to input a number again. or something like that
You can't loop on avg, since it's computed from a through h. Consider: right after you hit r, everything gets zeroed out; you don't want the user to enter a number somewhere. If this is an assignment, then your instructor (should have) gave you guidelines that should tell you what to print when the average doesn't exist.
is there any way to fix it

What do you mean? Do you mean he printed 0 for the average? Then check for i=0, and print 0 instead of calculating the average.
