When a decision needs to be made in a computer program or an algorithm selection is used. This is typically done using conditional statements, the most common conditional statements are IF, THEN, ELSE. There are three basic building blocks (constructs) to use when designing algorithms: These building blocks help to describe solutions in a form ready for. adj. Selection: Sometimes you only want some lines of code to be run only if a condition is met, otherwise you want the computer to ignore these lines and jump over them. When a decision needs to be made in a computer program or an algorithm selection is used. Depending on the answer given, the algorithm will follow certain steps and ignore others.
