Which loop statement always executes the body at least once?

Which loop statement always executes the body at least once?

Which loop statement has at least one body execution?

do loop

Which loop executes at least once?

do-while loop

Which of the following for loop will cause the body of the loop to be executed 10 times?

Which of the following for loop headers will cause the body of the loop to be executed 10 times? Explanation: When i equals 0, 1, 2, 3, 5, 6, 7, 8, or 9, the loop executes. Therefore it executes exactly 10 times.

Which loop is best to use if the loop may or may not need to run at all?

In this example, a Repeat loop would be a better choice.

Which is better for or while loop?

In general, a for loop is used when the loop should be run a certain number of times. A while loop is used to cause the loop’s failure based on something other than its number of runs.

What is the difference between the while loop and for loop?

The ‘for’ loop is used when we know the number of iterations. The ‘while loop is used when the number iterations are not known. The loop iterates infinitely if the condition is not placed in the ‘for” loop. It is a compilation error if the condition is not placed in the ‘while” loop.

What is the difference between while and do while?

The main difference between a while and do while loops is that the while loop checks the condition before iterating the loop. The do-while loop, on the other hand verifies the condition following execution of statements within the loop.

How does a while loop work?

Overview. The while construct consists of a block of code and a condition/expression. This loop continues until the condition/expression is false. The control structure is also known as a “pre-test loop” because it checks the condition/expression before execution of the block.

What is a counting loop?

A common type of program loop is one where an integer counts up from an initial value to an upper limit. This loop is known as a counting loop. The loop must be completed with the correct count. The counter must be incremented.

What is loop and its types with example?

A loop in computer science is a program structure that repeats a series of instructions until a particular condition is met. Loops are used by programmers to cycle through numbers, add sums, repeat functions, and other tasks. The while loop and for loop are two of the most popular loop types. …

Which of the following is the loop control statement?

Read:  What are the three components of scientific attitude?

You can execute the same block of code repeatedly with loop control statements. Loop control statements can be used to execute a block of code repeatedly. Statements loop for as long as the condition is true.

Which of the following is a loop statement?

Answer. While loop is executed only once before the condition is verified. Its syntax is do //body of loop; while (condition). If the condition evaluates as true, then the body of the loop within the do statement is executed once more.

What is a loop statement that never resolves to a false value?

A loop is considered infinite if it never resolves to a FALSE condition. While loops should be used with caution as this could lead to the condition never being resolved to a true value. This creates a loop that never ends. This loop is known as an infinite loop.
