Please help to look at, the program went wrong?-CodePudding

This program reservation management system is the design of the background, features order, query, modify, delete, view existing reservation list, exit systems, translation no errors, but running in the query, modify, and delete the error in the three functions, select the Numbers for 1 for function operation no problem, but the number is 1 will come out a design first after an error "no query to modify/delete data", but the selection function can continue to run, can modify delete as usual, for example, every back to the first error, just don't know what the problem with the program, please help to look at it?

Procedure is as follows:
