C++ - Simple Math Interpreter V2

I made this for fun, so there may or may not be some bad practice or anything like that! If there is an issue, I'm willing to fix it, but I do not have a lot of knowledge with C++.

An interpreter, written in C++, that can evaluate simple math calculations.

This is written in C++11.

V1

My first simple math interpreter:

V2 (this)

Improvements:

• Smart pointers instead of raw pointers.
• More similar to CodePulse's Python Simple Math Interpreter code
• Inheritance with classes, including use of virtual functions (polymorphism)
• CMakeLists.txt added to build with CMake
• In general, more use of C++11 features

V2 does not have the power operator like in V1.

Running the program

If you are using G++ (GNU Compiler Collection), there is a compile.txt, so you can compile the interpreter into an executable file.

You can also build with CMake. In a terminal, go to the root directory and run

cmake .
make
./CPP-Simple-Math-Interpreter

to compile and execute the math interpreter.
