Is a loop construct that will always be executed once?

16) Which one of the following is a loop construct that will always be executed once? Explanation: The body of a loop is often executed at least once during the do-while loop. Once the body is performed, the condition is tested.

while statement creates a loop that executes a specified statement until the test condition evaluates to false. The condition is evaluated after executing the statement, resulting in the specified statement executing at least once.

When a continue statement is executed in a?

The continue statement is used inside loops. When a continue statement is encountered inside a loop, control jumps to the beginning of the loop for next iteration, skipping the execution of statements inside the body of loop for the current iteration.

Which loop is faster in C language?

Some situation, we can use while loop or do-while loop interchangeably. One of my friend told me that such situation we should use do-while loop. Because it is faster than while.

Is for loop faster than while?

The main reason that While is much slower is because the while loop checks the condition after each iteration, so if you are going to write this code, just use a for loop instead.

Can we use continue in while loop?

The continue statement is used in loop control structure when you need to jump to the next iteration of the loop immediately. It can be used with for loop or while loop. … We can use Java continue statement in all types of loops such as for loop, while loop and do-while loop.

What is difference between Do and while loop?

do-while loop is similar to while loop, however there is a difference between them: In while loop, condition is evaluated first and then the statements inside loop body gets executed, on the other hand in do-while loop, statements inside do-while gets executed first and then the condition is evaluated.

Can we write for loop in while loop?

All for loops can be written as while loops, and vice-versa. … In general, you should use a for loop when you know how many times the loop should run. If you want the loop to break based on a condition other than the number of times it runs, you should use a while loop.

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.

What is the minimum many time’s a do-while loop is guaranteed to run?

Do while will execute atleast one time.. and it is guaranteed. This happens because we execute code block first and then check condition.

What is the maximum number of times does a do-while loop gets executed?

5 Answers. The While loop in VB.Net has no inherent limitation on number of iterations. It will execute exactly as many times as your code says it should.

Can we use continue statement without using loop?

The continue statement can be used with any other loop also like while or do while in a similar way as it is used with for loop above. Exercise Problem: Given a number n, print triangular pattern. We are allowed to use only one loop.

Does Break stop all loops?

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.

What is the effect of writing a Continue statement inside a loop?

According to: When the continue statement is executed inside a loop-statement, the program will skip over the remainder of the loop-body to the end of the loop body.

In which loop condition is tested after first iteration?

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. If it is true, the code executes the body of the loop again.

Which two statements are true about the while loop?
