The program asks the user which department they would like to enter. Goes into that department and then asks user what would they like to do inside that department. At end of whatever user would like to do the inner while loop asks "what is next?". If user enters "0" they are taken back to the question of "which department would they like to enter, user enters the index for corresponding department, but the loop does not go back into whichever department the user chooses.
In short: the outer while loop executes, and proceeds to the switch statements with inner while loops, but when the user returns to the outer while loop - that loop does not reenter the user specified department.

any help would be appreciated!
CodePudding user response：
Clear out subindex in the outer loop. What is probably happening is that you get an index of 1 and do the first of the switch statements. You then get subindexes for a while until they hit 0, then you go back to the outer loop. Pick 2 this time.
But subindex already has a 0 in it, so the while loop exits right away.
This code would be a LOT safer if you made better use of functions. Each of the inner loops could be a separate function. That would eliminate variables drifting from one of the switch conditions to the next one the next time around. And the code would be more readable.
