Nov 17Titration Frustration
by in CodeSOD on 2017-12-19
From submitter Christoph comes a function that makes your average regex seem not all that bad, actually:
According to "What is a Titration?" we learn that "a titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution." Since this is an often needed calculation in a laboratory, we can write a program to solve this problem for us.
Part of the solver is a formula parser, which needs to accept variable names (either lower or upper case letters), decimal numbers, and any of '+-*/^()' for mathematical operators. Presented here is the part of the code for thesolveTitration()function that deals with parsing of the formula. Try to read it in an 80 chars/line window. Once with wrapping enabled, and once with wrapping disabled and horizontal scrolling. Enjoy!
