Computer Science 2.1.4

1. Structured Approach

   • The structured programming approach aims to improve the clarity of programs. Only 3 basic structures are used: Sequence, Selection and Iteration.

2. Tools for Designing Algorithms

   • Flow diagrams and pseudocode are two methods used to design algorithms. Pseudocode corresponds to the iteration structures and is generally more useful for designing algorithms.
   • Most logic errors that occur in programs occur at points where decisions are made. This applies to both selection and iterative structures.

3. This code intends to print out the number of values between a lower and upper bound, that are divisible by 3, 5 or both.

4. The output should be 7 but the output will be 10 as 0 and 15 will be counted twice.
