Programming Concepts
Gbogbo ọrọ náà
Every program, however large, is built from a small set of ideas: store a value, get input, produce output, make a choice, repeat something, and break the work into named pieces. Learn these building blocks once and you can read and write programs in any language, because the same concepts hide under different words in Python, Java or pseudocode.
In this lesson you will declare variables and constants, use the core data types, master sequence, selection and iteration, count and total, handle strings, nest statements inside one another, and split a program into procedures and functions with parameters. You will write all of it in the Cambridge pseudocode style used in the exam.
