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.

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.

A selection in programming is used to make choices depending on the information. An algorithm can be made smarter by using IF, THEN, and ELSE functions to reiterate instructions, or to move the process in question to different parts of the program. Selection is also called a decision.

Selection allows there to be more than one path through a program. Many solutions feature several choices or decisions. These decisions lead to different paths through the program.

Aug 31, 2018 · Selection – selecting which path of an algorithm to execute depending on some criteria. For example, if you passed a class in school, then we execute the operations that clap and cheer and play a song. But if you didn’t pass the class, then maybe we would say, “Better luck next time, hang in there!” Iteration – looping or repeating.

Programs are designed and implemented using common building blocks, known as programming constructs. These constructs are sequence, selection and iteration and they form the basis for all...

Nov 2, 2020 · Selection structures, more commonly known as conditional structures or if-then structures, are a fundamental feature of computer programming. It is difficult to conceive of any non-trivial program without at least one such structure.

Selection is one of the three logical structures in programming that allows you to control the flow of the program. You do this by giving a condition and if it's met, do something. If it is not met, do something else.

One-Way (if) Selection. Using One-Way (if) Selection: Syntax of one-way (if) selection: if (expression) statement1; statement2; if is reserved word; expression must evaluate to true (nonzero) or false (0) statement1 executed if value of expression true; statement1 bypassed if value false; program execution moves to statement2
