Exception Handling

DEnumber50 (147)
In this program I am trying to catch the out of bounds input from the user. I have options for 1 and 2, but would like to have an exception put out a message if they go below one or above two. I have added the exception as I see it should work and I am getting errors. I don't have line numbers it states error LNK2005 and error LNK1169. Please let me know if there is a more effective way to do this.

No idea what linker errors you're getting. Please post the FULL text of the linker errors.

Since you did not post employee.cpp, was unable to compile and link your program.

class outOfBoundsNumber
{
/*...*/
} myex;

myex is a variable defined in header file.
If you include it more than once, you will have multiple definition error.

Solution: never have variable definition in header file.
