While Loop Assistance
I have a question about While Loops... can you have a complex boolean expression in a while loop?
I wrote a program a while back that added up golf scores and did random functions to the scores you put in. When I wrote it, it allows the user to enter in an indefinite number of scores, but allows the user to enter "-1" to terminate the while loop. I'd like the user to still have that option, but I'd like to limit the amount of entires that they can put in to only 10 entires... I tried using this expression to replace the while loop below:while ((golfScore!= -1) || (rounds == 10))
but that doesn't seem to work.
Any help here is appreciated. Here is my complete code. I want to have the code doe everything it does below, but instead of an indefinite amount of entries, I want to limit it to 10. Thank you in advance.
