My codes are correct

Be sure, if it does not do what you want, it is not correct.

And since you did not tell what you want to do with this code, it is not easy to help you.

[rdtr3548]

You put Electric Billing Service next to Water Billing Service. This is causing a short circuit.
Also if the screen isn't clearing either possibly add include <windows.h> if you are on windows or, if you are on linux, replace system("cls") with system("clear"), which is something I googled in the name of the people.

Sir rodiongork
can you help me to solve the short-circuit in my program 'coz it makes me dizzy thinking about this problem :|
Thanks to your Help and God bless :D

The two must be separate it is very dangerous. I am sorry if you have already lost family to this. I should have replied sooner.
