postfix-calculator

Simple integer Calculator in Reverse Polish Notation. It does support double when using the power of ^

by converting the passed integer to double to use the "pow" math function

To compile just run

     $ make

Will compile both the strtok and rpncalc binary files

To compile just one of the two binaries:

     $ make strtok
     $ make rpncalc

The strtok.c contains the tokenizer that changes infix statement to the postfix:

You pass the infix arguments to the strtok as:

     $ ./strtok "((3+5)*7)/2"

The output:

     $ 3 5 + 7 * 2 /

You then pass the results to the rpncalc as:

     $ ./rpncalc "3 5 + 7 * 2 /"
     $ 28

You can pipe it to rpncalc like this:

     $ ./strtok "((3+5)*7)/2" | ./rpncalc
