When designing programs, there are often points where a decision must be made. This decision is known as selection, and is implemented in programming using IF statements. A sequence of logical...

The basic attribute of a selection control structure is to be able to select between two or more alternate paths. This is described as either two-way selection or multi-way selection. A question using Boolean concepts usually controls which path is selected.

Surprisingly, it can often be broken down into three simple programming structures called sequences, selections, and loops. These come together to form the most basic instructions and algorithms for all types of software. Watch the video below to learn more about sequences, selections, and loops.

Aug 27, 2018 · SELECTION. Selection logic, also known as decision logic, is used for making decisions. Selection logic is depicted as either an IF…THEN…ELSE or IF…..THEN structure. Selection is the decision-making construct. It is used to make yes/no or …

• switch statement: Provides for one selection from many alternatives • switch keyword starts the statement – Is followed by the expression to be evaluated • case keyword identifies a value to be compared to the switch expression – When a match is found, statements in …

Selection – This is where you select or choose between two or more flows. The choice is decided by asking some sort of question. The answer determines the path (or which lines of code) will be executed. Iteration – Also known as repetition, it allows some code (one to many lines) to be executed (or repeated) several times.

5.1.2. Selection Selective execution allows programs to select their behavior based on an appropriate condition and can be visualized as shown in the diagram to the right. Execution flows from the top to the logical condition. If the expression evaluates to true, then the selected statement is executed, otherwise

Learning computer programming is a long process. First of all, students have to be familiar with basic control structures: sequence, selection, and iteration. Furthermore, they also need to...

Aug 31, 2018 · Sequence – the order we want the computer to execute the instructions we provide as programmers. For example, do this first, then do this, then do that, and so forth. Selection – selecting which path of an algorithm to execute depending on some criteria.
