Calculator

🧮 A minimal implementation for an integer calculator in pure C. It uses reverse polish expression to do the calculating as follows: 1*(2+3) => 1 2 3+* => 5

Install:

git clone git@github.com:Mivinci/calculator.git
cd calculator
make
make install

Usage:

To calculate 1*(2+3), just run:

calc 1*(2+3)

Or you might want to view the reverse polish expression:

calc 1*(2+3) -c

Or just run calc to enter input mode:

calc
>> 1*(2+3)
5
