# What Is Selection In Computer Science?

## What is an example of selection in computer science?

Think of selection as the situations in programming where we need our code to branch out (flow differently), taking different paths depending upon a condition. For example, imagine losing a life in a computer game.

## What is selection and iteration?

Selection determines which path a program takes when it is running. Iteration is the repeated execution of a section of code when a program is running.

## What does selection mean in an algorithm?

What is selection? An explanation of selection, as used in algorithms and programming. Transcript. Selection is a decision or question. At some point in an algorithm there may need to be a question because the algorithm has reached a step where one or more options are available.

## What is mean by selection in C language?

Selection statements allow a program to test several conditions, and execute instructions based on which condition is true. That is why selection statements are also referred to as conditional statements.

## What is an example of selection in coding?

Selection is the process of making a decision. The result of the decision determines which path the program will take next. For example, a program could tell a user whether they are old enough to learn how to drive a car.

## What is a selection structure?

Selection Structure. Use to make a decision or comparison and then, based on the result of that decision or comparison, to select one of two paths. The condition must result in either a true (yes) or false (no) answer.

## What are the 2 types of iteration?

There are two ways in which programs can iterate or ‘loop’:

• count-controlled loops.
• condition-controlled loops.

## What are the 3 parts of an algorithm?

Three main stages are involved in creating an algorithm: data input, data processing, and results output. The order is specific and cannot be changed.

## What is iteration in coding?

An explanation of iteration, as used in algorithms and programming. Transcript. Algorithms consist of steps that are carried out (performed) one after another. Sometimes an algorithm needs to repeat certain steps until told to stop or until a particular condition has been met. Iteration is the process of repeating

## How does the selection algorithm work?

Selection Algorithm is an algorithm for finding the kth smallest (or largest) number in a list or an array. For finding the minimum (or maximum) element by iterating through the list, we keep the track of current minimum (or maximum) elements that occur so far and it is related to the selection sort.

## Why do we use selection in programming?

Why is selection important? Selection allows there to be more than one path through a program. These decisions lead to different paths through the program. These paths represent the result of making a choice.

## What is selection in flowchart?

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.

## Is IF statement a selection?

The simplest form of selection is the if statement. This is sometimes referred to as binary selection since there are two possible paths of execution. The boolean expression after the if statement is called the condition. If it is true, then the immediately following indented statements get executed.

## Is switch a selection statement?

In computer programming languages, a switch statement is a type of selection control mechanism used to allow the value of a variable or expression to change the control flow of program execution via search and map.

## What is else selection?

In programming, selection is implemented using IF statements. Using IF and ELSE gives two possible choices (paths) that a program can follow. To do this, the statement ELSE IF is used. This simple algorithm prints out a different message depending on how old you are.
