What structure is used when a set of statements in repeated many times?
Answer: A repetition structure is also known as a loop. While and do-while statements are condition-controlled loops because they usea true/false condition to control thenumber of times it repeats. A for loop is a count-controlled loop because it repeats a specificnumber of times.
What are the types of repetition control structure?
A repetition statement that both defines the boundaries containing the repeating section of code and controls whether the code will be executed or not. There are three different forms of Visual Basic repetition structures: Do While structures, For structures, and Do/Loop Until structures.
What is the Do While repetition structure?
The do while construct consists of a process symbol and a condition. First, the code within the block is executed, and then the condition is evaluated. If the condition is true the code within the block is executed again. This repeats until the condition becomes false.
How can a repetition control structure be useful?
The other type of important programming control structure is a repetition statement. A repetition statement is used to repeat a group (block) of programming instructions. Most beginning programmers have a harder time using repetition statements than they have at using selection statements.
Is while a control structure?
Overview. The while construct consists of a block of code and a condition/expression. Because the while loop checks the condition/expression before the block is executed, the control structure is often also known as a pre-test loop.
When a Do While loop is run the loop is guaranteed to execute at least one time?
The only loop that will always get executed is the do while loop. As far as the do while loop is considered then the condition is not evaluated until you reach the end of a loop. Because of this nature of it a do while loop will always get executed at least once.
