Agnostic Programming: studying to layout and try out simple Programming Algorithms is written for rookies who are looking to study uncomplicated programming strategies with no the main points of any specific programming language. instead of an in-depth dialogue of programming syntax and pointless definitions, this brief publication introduces the center, foundational programming constructs with a test-driven technique. brief, yet hard programming workouts are discovered on the finish of each bankruptcy. an outstanding first programming publication for college students who will proceed to software in a number of languages, with a heavy specialize in challenge fixing and checking out.

I like sum) The small program above can be translated into any number of programming languages – this is the easy part. The hard part is to come up with a series of steps – the program itself, that are steps that a computer can understand. Recall that the computer knows how to do calculations (like addition), but you, the programmer, need to tell it what to add. One goal in this book is to get you, the reader, to be able to refine a word problem into a series of ordered steps that a computer can understand.
Answer: If the bug was that the order of the inputs was accidentally flipped, the test case with 1 and 1 would not reveal this fault. Although the inputs of 1 and 1 are perfectly valid inputs to our code, as a test case they provide us with less information than other tests we could write. In this book, we will learn to focus on finding effective tests that reveal the most information, and this will always depend on our knowledge of what programming language constructs we have learned so far. Testing is a skill that improves with practice and knowledge.
So yes, we’d need all three ways to satisfy the equation side + side > side, just as we did for invalid triangles. In practice, however, we could probably write our program such that if we know it’s not an equilateral, and it’s not an isosceles, and it’s not an invalid triangle, it must be scalene, so one test might have been enough, assuming the other parts of the code were tested adequately. I’ll leave the other tests for scalene out for now, but in doing so I have bound myself to a particular implementation of the solution here.
