Learn how to represent selection in algorithms in Bitesize KS3 Computer Science.

Jan 10, 2025 · It is used to decide whether a certain statement or block of statements will be executed or not i.e if a certain condition is true then a block of statements is executed otherwise not. Syntax of if Statement

I would say that "Method 2" is a standard way of showing this selection flowchart, as a decision (diamond) doesn't usually have both boolean outputs leading to the same point.

The selection control structure allows one set of statements to be executed if a condition is true and another set of actions to be executed if a condition is false. A selection structure, also called an "If-Then-Else" structure, is flowcharted as follows:

The sequence of steps in a flowchart is from Start to Stop, moving down the flowchart from one step to the next. However, when selection is used, the next step(s) will depend on a condition. IF statements. An IF statement is the most fundamental form of selection.

Selection: The if and if/else statement The basic method to perform selection in C is to use the if statement. The if statement allows you to do something if an expression is true, and do nothing if it is not.

Right-click on the workspace >> Insert selection. We can nest many selection symbols when we make multiple decisions in the flowcharts. Let’s see a sample usage of the flowchart using the Selection symbol. PRINT x + " > " + y. IF x = y THEN. PRINT x + " …

VB 2008 addressed this inefficiency with the introduction of a short-circuited If function. When the situation arises where you need to choose between more than two alternatives, an extended form of the selection structure, called the case structure, must be used. A flowcharted example follows:

understand how selection statement works. know how to analyze selection statement. know how to write selection statement. know how to apply selection statement in problem solving.

When designing algorithms, there are many steps where decisions must be made. This decision is known as selection, and can be displayed in pseudocode or flowcharts. Selection in practice: How...
