C Help I cant find whats wrong in my program The sample outp

C++ Help, I can\'t find what\'s wrong in my program. The sample output is below and the program I wrote is below that. I\'m having issues with the \"12 hour mode is turned on\", and now I\'m getting all sorts of errors. Anything helps. Thank you.

-In this project, the “current time” should be stored in 24-hour format. Only when the user actually interacts with the program will the output and input be sometimes in 12-hour format. Implement a main menu that will allow the user to (1) enter the current time, (2) add a forward delta to the “current time”, (3) add a backwards delta to the “current time”, (4) display the current time, (5) toggle the interface mode between 24-hour and 12-hour (should impact both getTime and printTime). The program should identify invalid input for the main menu. When entering the current time, only allow hours between 0 and 23 and minutes between 0 and 59. Accept only ‘a’ and ‘p’ when entering the time in 12-hour mode. When entering time deltas, only allow positive values or 0 (this is true for both forward and backwards time deltas).

Sample Output: (user input in italics)
