What is an example of a while loop?

A “While” Loop is used to repeat a specific block of code an unknown number of times, until a condition is met. For example, if we want to ask a user for a number between 1 and 10, we don’t know how many times the user may enter a larger number, so we keep asking “while the number is not between 1 and 10”.

What is the difference between a for loop and a for in loop?

for — loops through a block of code until the counter reaches a specified number. for…in — loops through the properties of an object. for…of — loops over iterable objects such as arrays, strings, etc.

What is for loop explain with example?

A “For” Loop is used to repeat a specific block of code a known number of times. For example, if we want to check the grade of every student in the class, we loop from 1 to that number. When the number of times is not known before hand, we use a “While” loop.

What is while loop in Python?

Python While Loop is used to execute a block of statements repeatedly until a given condition is satisfied. And when the condition becomes false, the line immediately after the loop in the program is executed. While loop falls under the category of indefinite iteration.

What is a while loop statement?

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.

Do While VS while example?

Here, statement(s) may be a single statement or a block of statements. The condition may be any expression, and true is any nonzero value. The loop iterates while the condition is true….Output.

While Loop	Do-While Loop
The while loop may run zero or more times	Do-While may run more than one times but at least once.

Can I replace while loop with for loop?

Accept Solution Reject Solution. You can replace every for, foreach or do/while loops with ‘while’ loops but ythe opposite is not true… ‘for’ loops are looping for a quantifiable number of iterations : your example (do/while) might well run forever if exit condition is never met.

Can we write a loop as a while loop?

As you already know that while loop body can contain statements, we can write while loop inside while loop. While loop inside another while loop is called Nested While Loop.

Is a while loop always an indefinite loop?

While loop is a type of indefinite loop.

The while loop executes the block of code until the condition is true.

We mostly use while loop when we don’t know how many times the loop will actually execute at runtime.

In simple terms when iterations of a loop are known then we mainly use for loop and when iterations are unknown then we use while loop.

What type of loop is the while loop?

A do-while loop is a kind of loop, which is a kind of control statement. It is a loop with the test at the bottom, rather than the more usual test at the top.
