Question: Can You Put A While Loop In A While Loop?

Can you have a while loop in a while loop?

A nested while loop is a while statement inside another while statement.

In a nested while loop, one iteration of the outer loop is first executed, after which the inner loop is executed.

Once the condition of the inner loop is satisfied, the program moves to the next iteration of the outer loop..

How do you convert a for loop to a while loop?

In order to convert for loop to while loop in C just move the loop control variable above the while and Increment/decrement expression inside the loop….//A simple for loop.for(int i=0; i<10; i++){//Print i.}//An equivalent while loop.int i=0;while(i<10){//Print i.More items...

How do you end a while loop?

TipsThe break statement exits a for or while loop completely. To skip the rest of the instructions in the loop and begin the next iteration, use a continue statement.break is not defined outside a for or while loop. To exit a function, use return .

Can you put a while loop in an if statement?

Using an assignment in the condition part of a while or if statement is generally not recommended, because it makes the code less readable. There’s an assignment in the while condition/loop.

What is for loop while loop and do while loop?

As we saw in a while loop, the body is executed if and only if the condition is true. In some cases, we have to execute a body of the loop at least once even if the condition is false. … In the do-while loop, the body of a loop is always executed at least once. After the body is executed, then it checks the condition.

How do you end a while loop in Java?

Break statement in javaWhen the break statement is encountered inside a loop, the loop is immediately terminated and the program control resumes at the next statement following the loop.It can be used to terminate a case in the switch statement (covered in the next chapter).

How does a while loop start?

First, we set a variable before the loop starts (var i = 0;) Then, we define the condition for the loop to run. As long as the variable is less than the length of the array (which is 4), the loop will continue. Each time the loop executes, the variable is incremented by one (i++)

Why while loop is better than for loop?

A do/while loop will always execute the code in the do{} block first and then evaluate the condition. do { //gets executed at least once } while (condition); A for loop allows you to initiate a counter variable, a check condition, and a way to increment your counter all in one line.

What are the four elements of a while loop in Python?

Loop statements usually have four components: initialization (usually of a loop control variable), continuation test on whether to do another iteration, an update step, and a loop body.

Is if else loop?

C If else statement If condition returns true then the statements inside the body of “if” are executed and the statements inside body of “else” are skipped. If condition returns false then the statements inside the body of “if” are skipped and the statements in “else” are executed.

How do you end a while loop in Python?

The Python break statement immediately terminates a loop entirely. Program execution proceeds to the first statement following the loop body. The Python continue statement immediately terminates the current loop iteration.

Can you have a while loop inside a while loop Python?

Syntax. A final note on loop nesting is that you can put any type of loop inside of any other type of loop. For example a for loop can be inside a while loop or vice versa.

What is Loop example?

A loop is used for executing a block of statements repeatedly until a particular condition is satisfied. For example, when you are displaying number from 1 to 100 you may want set the value of a variable to 1 and display it 100 times, increasing its value by 1 on each loop iteration.

Can we use if in while loop?

Using an if-else Statement within a while loop in R Returning to our scenario where 10 wins allows Team A to make the playoffs, let’s add an if-else conditional. The if-else conditional will go between the brackets of the while loop, in the same place we put it into the for loop earlier.
