This is something I'm using to learn C++.
To run, compile using your favorite tool. The command output will look like:
welcome to horrible calculator
enter an expression or press 'e' to exit.
>>The available operations are: +, -, *, / and this only works with integers.
An example:
welcome to horrible calculator
enter an expression or press 'e' to exit.
>> 33-3
found - at 2
33
3
calc = 30
enter an expression or press 'e' to exit.
>>It's very easy to break:
enter an expression or press 'e' to exit.
>> cc
no operators found
(and more errors)You probably don't want to do your taxes with this program.
