A while loop is an entry controlled loops that execute only if a given condition evaluates to true. Ruby uses the while keyword to define the while loop. An infinite loop is a loop that never ends itself, i.e.
The while loop is an entry-controlled loop. In an entry-controlled loop, the condition is checked first and if the condition is true then the statements within the loop body are executed. While in an exit-controlled loop, the condition is checked after executing the loop body. The do......
Java while LoopJava's while loop is an entry-controlled iterative statement. It has the following syntax in a Java program: while (booleanExpression) Statement //single or a block enclosed in { and } Java's while loop keeps executing the booleanExpression and Statement repeatedly until the ...
The while loop is an entry-controlled loop.The purpose of a while loop is to execute a statement or code block repeatedly as long as an expression is true. Once the expression becomes false, the loop terminates.Flow ChartThe flow chart of while loop looks as follows −Syntax...
There are two kinds of loops- entry controlled loop and exit controlled loop.A while loop in C++ is an example of an entry-controlled loop wherein the condition is checked at the entry of the loop. The loop runs until the condition is true, and the statements/ block of code inside the...
Note:the "for" loop is anentry controlled loop, which means that first, the evaluation of the loop condition happens, and then the iteration will start. So, if the condition fails at the start, then the loop will not execute even once. ...
The while loop is an entry-controlled or top-tested loop as the loop control or test appears in the beginning of the loop. The flowchart of the while loop is given in fig. The execution of the while loop proceeds as follows: Initially, test expression expr is evaluated. If it evaluates...

An example of such a scenario would be when you want to exit your program depending on the user input. For and while loops are examples of an entry controlled loop, as the test condition is checked before entering the loop body. Read Do While Loop: Definition, Example & Results Lesson ...
loop is called exit controlled loop, whereas awk while loop is called as entry controlled loop. Because while loop checks the condition first, then it decides to execute the body or not. But theawk do whileloop executes the body once, then repeats the body as long as the condition is ...
