ASCII character converter

I made an ASCII character converter. You can input an int and it gives you the character with the same value or opposite.

Please choose convertor int to char'a', char to int'b'
a
Enter your int:

do you have any questions?

By the way: line 60 is wrong

Whoops i forgotten to write the question. The question is when i choose the int to character converter and when it asks me to write an integer i put a character example(Console:Enter an integer User: a) it goes to an infinite loop. Why?
Also line 60 is correct!

The reason is that after entering incorrect characters cin is in error state. You can determine this with bad(). Read this:

call clear to get out of the error state:
