I'm getting multiple errors.. I've tried this with different variables and different data types. I clearly don't understand how to use pointers properly. I am not looking for someone to give me the answer, I would like to learn more and figure it out myself if possible however I am stuck - any advice is greatly appreciated.
I am always upfront - this is for an assignment for school. I have completed and met all of the other grading requirements, except the requirement of using at least one example of a pointer in my function.
The example here, I am trying to use a pointer with double employeeSalary in main and in case 2 as well. Earlier I was trying to use them with my function prototypes, but that didn't seem to work either. I am getting Exception thrown at 0x00007FFB0897EBCE (msvcp140d.dll) in ConsoleApplication5.exe: 0xC0000005: Access violation writing location 0x0000000000000000.
