The Selection Structure Is Used When You Want A Program To Make A Decision.?

What is a selection structure in programming?

Also known as a conditional structure, a selection structure is a programming feature that performs different processes based on whether a boolean condition is true or false. If you want to test multiple conditions, then you can include an elseif structure within an if-end or if-else structure.

What control structure do you use to make a decision?

C has three major decision making instructions—the if statement, the if-else statement, and the switch statement.

Why is selection structure important in programming?

Why is selection important? Selection allows there to be more than one path through a program. Many solutions feature several choices or decisions. Without selection it would not be possible to include different paths in programs, and the solutions we create would not be realistic.

What are the three types of selection structures?

Control Structures – Selection

  • Sequential: default mode; Executed line by line, one right after the other.
  • Selection: decisions, branching; When there are 2 or more alternatives. Three types:
  • Repetition: used for looping, or repeating a section of code multiple times. Three types:

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 is control structure example?

Sequence is the default control structure; instructions are executed one after another. They might, for example, carry out a series of arithmetic operations, assigning results to variables, to find the roots of a quadratic equation ax2 + bx + c = 0.

What is a single alternative decision structure?

What is a single alternative decision structure? A decision structure that provides a single alternative path of execution. If the. condition that is being tested is true, the program takes the alternative path.

What are the three types of decision control structures in Visual Basic?

The three basic types of control structures are sequential, selection and iteration. They can be combined in any way to solve a specified problem. Sequential is the default control structure, statements are executed line by line in the order in which they appear.

How is selection used in programming?

Selection is a programming construct where a section of code is run only if a condition is met. In programming, there are occasions when a decision needs to be made. Selection is the process of making a decision. The result of the decision determines which path the program will take next.

Why C is most popular language?

The C programming language is so popular because it is known as the mother of all programming languages. This language is widely flexible to use memory management. C is the best option for system level programming language.

What statement do we use for selection in programming?

In programming, selections are usually denoted by the statements: IF and ELSE. For example, this simple algorithm prints out a different message depending on how old you are. Using IF and ELSE, the steps are as follows: Ask your age.

What are the three basic types of control structures?

Flow of control through any given program is implemented with three basic types of control structures: Sequential, Selection and Repetition.

What are the major types of repetition structures?

Repetition statements fall into two general categories; while loops and for loops. Although it is possible to write every loop as a while loop (or every loop as a for loop), this is not a good idea. While loops should be used if the number of repetitions is not fixed.

What are the two different ways to implement multi selections in C ++?

The else-if statement forms the nested structure for the multiway selection and switch statement consist of different case labels to make selection from the multiway selection. So, these are the two ways to do the multiway selection.
