What is the technique for Fixing Code Errors
grimes13
- Sep 5th, 2011
First off for me there is no one technique.
Generally I do this:
1. Find out what the error is and reproduce it.
2. Create a test that should pass if the error is fixed.
3. Make my code pass that test.
This is not info on how to find a bug but on how I would go about fixing one. -
Length Conversion Program
Write a program that will read in a length in feet and inches and will output the equivalent length in meters and centimeter. Use at least three functions: one for input, one or more for calculating, and one for output. Include a loop that lets the user repeat this computation for new input values until the user says he wants to end the program. There are meter in a foot, 100 centimeters in a meter,...

To fully understand the answer for this question, you need to be femiliar with the Polymorphism concept and an implementation of such virtual function would be for the Observer or Visitor Design Pattern.
