What are control statements in Javascript?

Control statements are designed to allow you to create scripts that can decide which lines of code are evaluated, or how many times to evaluate them. There are two different types of control statements: conditional statements and loop statements.

What is C++ control statement?

Control statements are how programmers indicate which sections of code to use at specific times. Control statements are elements in the source code that control the flow of program execution. They include blocks using { and } brackets, loops using for, while and do while, and decision-making using if and switch.

What are the three types of control statements?

Flow of control through any given function is implemented with three basic types of control structures:

  • Sequential: default mode. …
  • Selection: used for decisions, branching — choosing between 2 or more alternative paths. …
  • Repetition: used for looping, i.e. repeating a piece of code multiple times in a row.

Is while a control statement?

In most computer programming languages, a while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement.

What is the use of goto statement?

The goto statement is a jump statement which is sometimes also referred to as unconditional jump statement. The goto statement can be used to jump from anywhere to anywhere within a function.

What is the use of input statement?
