What happens when you have a for loop inside of another for loop?

Nested For Loops. 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.

Is it correct to use same variable for outer and the inner loop?

The behavior of the loop will be difficult to understand as the inner loop will affect the iteration variable of the outer loop; this is most likely a typo. The rule flags the condition expression in the inner loop that uses the same variable as the iteration variable of the outer loop….Example.

1	int x1 = 0;
15	}
16	}

How do you break the outer loop from the inner loop?

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

What loop automatically repeats the loop body at least once?

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. If the condition is true, then it will again execute the body of a loop otherwise control is transferred out of the loop.

Can a for loop contain another for look?

Yes, a for loop can contain another for loop.

Can you do loops in a for loop?

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.

What is outer loop and inner loop?

The “print a line of stars” loop is called an inner loop because it is the loop body of another loop. The “do something five times” loop is called an outer loop because it is not inside any other loop.

What is inner loop and outer loop?

How do you break out of two loops in Python?

Another way of breaking out of multiple loops is to initialize a flag variable with a False value. The variable can be assigned a True value just before breaking out of the inner loop. The outer loop must contain an if block after the inner loop.

Do while loops always execute once?

Contrast with the while loop, which tests the condition before the code within the block is executed, the do-while loop is an exit-condition loop. This means that the code must always be executed first and then the expression or test condition is evaluated.

What is the difference between inner loop and Outer Loop?

The nested loop is also called as inner loop and the loop in which the nested loop defined is an outer loop. The outer loop always executes first and the inner loop executes, the inner loop executes each time the outer loop executes once.

Can you put a loop inside of a loop?

Since the code block of a loop can include any legal C++ statements, you can place a loop inside of a loop. 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.

How to execute the body of a while loop at least once?

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. This type of operation can be achieved by using a do-while loop. In the do-while loop, the body of a loop is always executed at least once.

What happens when you break a loop in a nested loop?

In a nested loop, a break statement only stops the loop it is placed in. Therefore, if a break is placed in the inner loop, the outer loop still continues. However, if the break is placed in the outer loop, all of the looping stops.
