![]() ![]() There were 3 minor bugs found in testing.Ī lot has been lost in the past 15-20 years, due to "technological advancement". ![]() Then I was transferred to another area and a (admittedly bright) new-hire was given the task to actually code the algorithm. The flowchart got down to the details of variable names, etc. Detailed flow charts ran, I'm thinking, about 1000 lines. The algorithm makes use of the MOD operator, which is represented in Python using the sign. For our example, we will create an algorithm which determines whether a given whole number is even or odd. In this article we are looking at flowcharts for GCSE Computer Science. Using this technology I once did the design for an incredibly complex algorithm internal to a database system. Program statements in a particular language. It's harder to follow the flow of a long method, and there's no good way to make notes, highlight/underline lines, etc. Similarly, code reviews are less effective now that code is pre-reviewed online vs with fanfold listings. These were incredibly useful and we used them extensively in code reviews.īut then they did away with paper, and the charts are not nearly as useful if you can't set them on your desk and mark on them, and even if you print them out on letter-sized paper instead of fanfold you lose a lot of effectiveness because you can't easily stretch them out to see 3-4 pages at a time. Back from about 1980 to 2000 I used to "draw" a lot of "Chapin" charts - feed a PL/I sort of syntax into a program and it prints a form of flow chart on 14" wide fanfold paper.
