The condition/expression is evaluated, and if the condition/expression is true, … In the example above, you see a press any key prompt that waits until the user presses a key. For example, run echo command 5 times or read text file line by line or evaluate the options passed on the command line for a script. The loop is not executed at all if the expression is false at the start. If condition is true, all statements in statementblock are executed until the Wend statement is encountered. WHILE..WEND Statements. The loop in this example uses a for loop to collect the car names from the cars array: When the condition evaluates to FALSE, control is passed to the statement following the WEND. Otherwise, control moves to the next statement following the Wend for that loop. 15WHILE.BAS . . If the condition is False, the program continues directly following the Wend statement. Tant que la condition est vraie, les instructions sont exécutées en boucle (attention à ne pas créer une boucle infinie). The structure of a While….Wend Loop is very similar to the Do Loop. This Video is all about While Loop In Qbasic. The expression is tested before the loop is executed so the loop will be executed zero or more times. 9.5 The While….Wend Loop. We can think of control flow (how statements are encountered) like a river. If the expression is false (zero) initially, the statement block is not run. So you need to know how to use them efficiently to produce scalable and quality. Sub exemple() Do While [CONDITION] 'Instructions Loop End Sub. Standard: ECMAScript 1st Edition (ECMA-262) La définition de 'while statement' dans cette spécification. Method 2. Simple while Loops¶. Remarks. If the condition is True, the loop is executed until the program finds Wend and then jumps back to the While statement. The while statement evaluates expression, which must return a boolean value. If the While condition is true, you stay in the loop. Standard: Définition initiale: Compatibilité des navigateurs. Otherwise, the expression is false. Something must change the tested variable, or the while loop will never exit. If it is said that print n, ten times, so it will print n ten times if a certain condition is true. When condition returns false, the control comes out of loop and jumps to the next statement after while loop. The output will be . Overview. Ce tableau de compatibilité a été généré à partir de données structurées. La définition de 'while statement' dans cette spécification. Syntax. while expression, statements, end evaluates an expression, and repeats the execution of a group of statements in a loop while the expression is true.An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). The boolean condition is either true or false. If condition is still True, the process is repeated. In a While..Wend loop, if the condition is True, all statements are executed until Wend keyword is encountered.. The syntax of a While..Wend loop in VBScript is −. expression: If the expression is true the following statements up to the WEnd statement are executed. In most computer programming languages, a while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. While constructs are terminated not with an End While but with a Wend.. If this page has been helpful, you can support us! If you have read the previous chapter, about the for loop, you will discover that a while loop is much the same as a for loop, with statement 1 and statement 3 omitted. As Do While is more structured than While.....Wend loop, programmers usually use Do While statements. Each Wend matches the most recent While. For the rules regarding label use, see Section 13.6.2, “Statemen Return In this program we exit the ReturnIf5 method, and its inner while-loop, when a certain value is reached. Check out 15 C# Questions – For, While Loops and If Else Statements. While counter < 20 counter = counter + 1 Wend Note that this information is readily available in the documentation; just press F1.The page you link to deals with Visual Basic .NET, not VBA. Control then returns to the While statement and condition is checked again. VBScript For-Next Loop. While...WEnd statements may be nested. The do while construct consists of a process symbol and a condition. The while loop can be thought of as a repeating if statement. If the condition is still True, the loop is executed again. When the WEND command is executed, it returns control to the WHILE statement (where the condition is tested again). The purpose of the loop is to repeat the same code a number of times. If the expression evaluates to true, the while statement executes the statement(s) in the while block. If it is not True, execution resumes with the statement following the Wend statement. For and While are the general loop control statements used in C programming, along with Do-While loop. The following program block illustrates … In do- while loop, do-while is a condition that appears at the end of the loop. it takes the following form: While condition Statements Wend The above loop means that while the condition is not met, the loop will go on.
