if-then

1. 1

   A proposition or statement about what should or does occur when a certain condition is…

   A proposition or statement about what should or does occur when a certain condition is met.

   • Disposition statements are always tantamount to conditional if-thens. (“Glass is fragile” amounts to “If glass is subjected to a shock, it will break”; “Wood is combustible” comes to “If wood is exposed to fire, it will burn”; and so on.)
   • Over time, I created a list of some of my own if-thens: If I want to get a lot of original writing done, I go to the library, where I don’t have Internet. If offered wine, I decline.
2. 2

   A conditional statement

   A conditional statement; a line of code that specifies a Boolean condition to check and a statement to execute when that Boolean evaluates to true.

   • List Formatter makes properly-spaced & indented listings with page breaks; each statement on new line, if-thens and loops called out; a great de-bugger!
   • 1. The problem is well bounded, 2. There are many empirical if/thens that lead to a correct solution, 3. The total number of if/thens is sufficient to bring you close to a right answer (Mazur 1987).
