How does a double loop work?

When a loop is nested inside another loop, the inner loop runs many times inside the outer loop. ... In each iteration of the outer loop, the inner loop will be re-started. The inner loop must finish all of its iterations before the outer loop can continue to its next iteration.

What is a nested loop give an example?

If a loop exists inside the body of another loop, it's called a nested loop. Here's an example of the nested for loop. // outer loop for (int i = 1; i <= 5; ++i) // codes // inner loop for(int j = 1; j <=2; ++j) // codes .. Here, we are using a for loop inside another for loop.

Can a for loop contain another for loop?

A for loop can contain any kind of statement in its body, including another for loop. – The inner loop must have a different name for its loop counter i bl th t it ill t fli t ith th t l variable so that it will not conflict with the outer loop.

How do two for loops work in Java?

The placing of one loop inside the body of another loop is called nesting. When you "nest" two loops, the outer loop takes control of the number of complete repetitions of the inner loop. While all types of loops may be nested, the most commonly nested loops are for loops.

What is the purpose of using break in loop?

When a 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).

Why do we use two for loops?

Nested loops are useful when for each pass through the outer loop, you need to repeat some action on the data in the outer loop. ... For example, you read a file line by line and for each line you must count how many times the word “the” is found.

What are the 3 types of loops?

Loops are control structures used to repeat a given section of code a certain number of times or until a particular condition is met. Visual Basic has three main types of loops: for.. next loops, do loops and while loops.

Which loop is guaranteed to execute at least one time?

while loop is similar to a while loop, except that a do... while loop is guaranteed to execute at least one time.

Can a while loop be nested in a for loop?

Nested for Loops in Python

You can put a for loop inside a while, or a while inside a for, or a for inside a for, or a while inside a while.

What are the 3 parts of a for loop?

Similar to a While loop, a For loop consists of three parts: the keyword For that starts the loop, the condition being tested, and the EndFor keyword that terminates the loop.

Why is it called a for loop?

In computer science, a for-loop (or simply for loop) is a control flow statement for specifying iteration, which allows code to be executed repeatedly. ... The name for-loop comes from the word for, which is used as the keyword in many programming languages to introduce a for-loop.

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.
