Just put the "eval.cpp" and "eval.h" in your project directory, then include header file:
#include "eval.h"After that, you simply create Eval object (passing the expression string in constructor) and call makeEvaluation function
std::string expression = "3 * (3 + 3)";
auto eval = new Eval(expression);
auto value = eval->makeEvaluation();You can also dowload this whole repository (it was made in VS17) to run given examples.
- more tests
- custom to_string method (standard library one has too small precision)
