None Of The Above 2. How Many Times Will The Following While Loop Print 'Hello'? Int J = 1; While(j. As noted earlier, C has three repetition, or looping control structures that allow you to repeat a set of statements until certain conditions are met. Note: The variable that controls the loop is called loop control variable (LCV) While Looping Control Structures The first loop that we're going to discuss about is while loop. The iteration or repetition structure repeatedly executes a series of statements as long as the condition is true. The condition may be predefined or open-ended. 'While,' 'do/while' and 'for' loop are the three types of iteration statements. A loop can either be event controlled or counter controlled.
Repetition Control Structure C++ Definition
Repetition control structure is also known as looping or iteration control structure. .Repetition is the act of repeating steps in a certain process. It consists of a branching backwards away from the normal sequence of steps towards an earlier step. The branching decision is based on a relationship between the values of known data (condition) at the time that the branching test is performed. The condition is usually based on the value of a single variable (control variable). The steps to be repeated are referred to as the loop body. Each execution of the steps is referred to as a pass or iteration. The step where the body starts is called as the loop entrance and the step where the test branches back fails is known as the loop exit, it causes the repetition to stop.
It is a process of executing one or more steps of an algorithm or program repeatedly. Repetition is needed to add a list of numbers or variables for each number and one for the total would need to be declared. For a different number of values, recoding would be required. C++ has three repetition structures that repeat statements over and over until certain conditions are met. Repetition control system is very essential in programming for most programs do repetitious tasks.
2. What are the different types of repetition control structure?
The two basic types of loops are pre-test loop and the post-test loop.
PRE-TEST LOOP The pre-test loop can be put to in VB with a 'Do' statement followed by either the keyword 'While' or 'Until'. 'Do While' means execute the statements entered in the body of the loop While a certain condition is true. 'Do Until' means execute the statements in the body of the loop until a certain condition is true. While and Until are opposite to each other, doing something Until a condition is TRUE is the same as doing something While a condition is FALSE. Do While X 10. In C++, while is a reserved word. The expression acts as a decision maker. It is called the loop condition. The statement can be either a simple or compound statement. It is called the body of the loop.

The While/Wend Loop- it is an older statement pair from previous versions of BASIC and was included in VB for compatibility. The format is:
While
Wend
The following two code segments produce the exact same results:
|intNum = Val(InputBox('Enter a number')) |intNum = Val(InputBox('Enter a number')) | |Do While intNum > 0 |While intNum > 0 | | intNumSq = intNum ^ 2 | intNumSq = intNum ^ 2 | |Print intNum; 'squared is'; intNumSq | Print intNum; 'squared is'; intNumSq | | intNum = Val(InputBox('Enter a number')) | intNum = Val(InputBox('Enter a number')) | |Loop |Wend |
There is no 'Until' equivalent of 'While/Wend'
The For/Next Loop – it uses a built-in counting procedure to repeat a series of instructions a specific number of times. Let us compare counting with Do/Loop vs. counting with For/Next. With Do While, you could set up a loop to print the numbers from 1 to 5 as follows:
intCounter = 1
Do While intCounter
