calc::Calculator

A Calculator api created in C++. The goal for the api is to take a mathematical expression and calculate the value at runtime.

The project uses C++20 and the C++ Standard Library.

Code example

#include <iostream>
#include <string>

#include <calc/calculator.h>

int main() {
    calc::Calculator calculator;

    std::cout << "1 - (-(2^2)) - 1 = " << calculator.excecute("1 - (-(2^2)) - 1") << "\n";
    
    calculator.addVariable("pi", 3.1416f);

    std::cout << "2^2 * pi" << calculator.excecute("2^2 * pi") << "\n";

    return 0;
}

Output:

1 - (-(2^2)) - 1 = 4.0
2^2 * pi = 12.5664
