Help Finding the mode, calling fuction

Hi, i have this much done and i believe i have the right function down to find the mean of my randomly sorted array. However, i am having a problem figureing out where to call the MODE fuction and how to call can. Can you help? Thanks

and i realize i have a lot of other formating errors and such but i just want to make sure it works first. thanks

Those formatting errors make your code virtually unreadable. How can we help with code that is painful to read? If you spend an extra 30 seconds formatting your code before posting it here, more people would be inclined to help you.

is there anything that you can press that will auto-format it for you like in true basic or is it a thing you have to do yourself? thanks

Double posting.

Sorting Array Help

When you paste code from your IDE to here, the formatting will stay preserved. If your code looks the same in your IDE as it does posted above, then that is your first problem. You should keep your code formatted as you write it. It will make it much easier for you to spot bugs that are due to mismatched braces, missing parenthesis, bad scoping, etc.

Basically you've thrown some meaningless code into each of the three xxxSort() functions related to computing the median. You need to remove that, and (I guess) place some logic in main() to compute the median and print it (or whatever).

Your bubbleSort() function is also calling main() which is not allowed in C++.

Without knowing what you're trying to achieve (looking at random code which doesn't do what you want, does not explain much) it's hard to be more specifc.
