What is robustness
-
Programs can meet unexpected inputs because of user errors or invalid information from external files
When using input validation it is important to add a meaningful error message telling the user how to input a valid input
When validating data from a range, normal, extreme and exceptional data should be tested
When testing exceptional data it is good practice to test values just outside of the range as this is where you are most likely to catch an error

What is usability?
-
This includes how easy it is for people to learn how to use the program. Programs that are easier to use will often be built more intuitively
What is maintainability?
If your code is easy to read it will be a lot easier for other programmers or you in the future to maintain and add updates to your program
