How do you use multiple loops?

The inner loop is nested inside the outer loop. 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.

How do you break out of two for loops?

Breaking out of two loops

1. Put the loops into a function, and return from the function to break the loops. ...
2. Raise an exception and catch it outside the double loop. ...
3. Use boolean variables to note that the loop is done, and check the variable in the outer loop to execute a second break.

How do you do multiple loops in Python?

Nested for Loops in Python

You can also nest a loop inside another. 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. Or you can put a loop inside a loop inside a loop. You can go as far as you want.

How do double for loops 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.

Can we use for loop inside while loop?

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

What is the function of while loop?

The while loop is used to repeat a section of code an unknown number of times until a specific condition is met. For example, say we want to know how many times a given number can be divided by 2 before it is less than or equal to 1.

How do you break the outer loop?

There are two steps to break from nested loop, first part is labeling loop and second part is using labeled break. You must put your label before loop and you need a colon after the label as well. When you use that label after break, control will jump outside of the labeled loop.

Does break only exit one loop?

break can only exit out of an enclosing loop or an enclosing switch statement (same idea as an enclosing loop, but it's a switch statement). If a break statement appears in an if body, just ignore the if. Find the innermost enclosing loop or innermost switch statement.

Does Break stop all loops Java?

Java break and Nested Loop

In the case of nested loops, the break statement terminates the innermost loop. Here, the break statement terminates the innermost while loop, and control jumps to the outer loop.

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

To convert a for loop to while loop we need to simply add the initialization statement before the while loop.

1. /* For loop */ int i; for(i = 0; i < 10; i++) ...
2. /* While loop */ while(*str++ != NULL) length++; ...
3. /* Do while loop */ do. status = check_connection(); ...
4. /* For loop */ int i; for(i = 0; i < 10; i++)

What are the 2 loops in Python?

There are two types of loops in Python, for and while.

Can you have two for loops?

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.
