while wend control statement


This Video is all about While Loop In Qbasic. Example: Sub ExampleWhileWend Dim stext As String Dim iRun As Integer sText ="This is a short text" iRun = 1 while iRun < Len(sText) if Mid(sText,iRun,1 )<> " " then Mid( sText ,iRun, 1, Chr( 1 + Asc( Mid(sText,iRun,1 )) ) iRun = iRun + 1 Wend MsgBox sText,0,"Text encoded" End Sub. If this page has been helpful, you can support us! The Do...Loop While statement first executes the statements and then test the condition after each execution. The syntax of a While..Wend loop in VBScript is −. Loops and conditional constructs are an integral part of any programming language. The following program block illustrates … The expression is tested before the loop is executed so the loop will be executed zero or more times. A statement or series of statements to be executed during the loop. When the WEND command is executed, it returns control to the WHILE statement (where the condition is tested again). In the C# language we can use break, return and goto to change control flow in a while-loop. Computer programming language - Computer programming language - Control structures: Programs written in procedural languages, the most common kind, are like recipes, having lists of ingredients and step-by-step instructions for using them. 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. If a GoTo statement is encountered within a While…Wend loop, control passes to the location of the destination label named. When condition is true in while loop then control is given to next statement. expression: If the expression is true the following statements up to the WEnd statement are executed. 9.5 The While….Wend Loop. The structure of a While….Wend Loop is very similar to the Do Loop. The loop in the above example iterates 10 times, and after that, the value of ‘loop_ctr’ becomes 11, and hence the loop condition becomes false, and the control moves to the statement after the while when loop. In a While..Wend loop, if the condition is True, all statements are executed until Wend keyword is encountered.. Wend Statement. Each Wend matches the most recent While. e.g. We look at the two entry-controlled loops in detail to understand the difference between the two. When the WEND command is executed, it returns control to the WHILE statement (where the condition is tested again). While Condition [Statement] Wend. 3.3.1. These questions will help you to test and improve your C# programming skills. The following While...Wend counts from 1 to 100. Do...Loop While Statement. The expression result must be of type Integer. while(1) It is an infinite loop which will run till a break statement is issued explicitly. x=x+1 Wend The output will be . Control then returns to the While statement and condition is again checked. 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. The boolean condition is either true or false. When the condition evaluates to FALSE, control is passed to the statement following the WEND. int i = 0; while (i < 10) { Console.Write("While statement "); // Write the index to the screen. If it is said that print n, ten times, so it will print n ten times if a certain condition is true. As Do While is more structured than While.....Wend loop, programmers usually use Do While statements. Otherwise, the expression is false. A Python while loop behaves quite similarly to common English usage. PRINT "Press any key to continue" WHILE INKEY$ = "" WEND. When condition returns false, the control comes out of loop and jumps to the next statement after while loop. The statement block is run repeatedly as long as the expression evaluates to true (nonzero). while [Control Structure] Description. The do while construct consists of a process symbol and a condition. A WHILE..WEND statement contains an expression that controls the repetitive execution of a statement block. When the Wend statement is encountered, the next iteration starts. statements ElseIf < condition 2 > Then statements ElseIf < condition 3 > Then statements Else Statements End If. The while construct consists of a block of code and a condition/expression. [begin_label:] WHILE search_condition DO statement_list END WHILE [end_label] The statement list within a WHILE statement is repeated as long as the search_condition expression is true. Each while loop consists of a set of commands and a condition. Otherwise, control moves to the next statement following the Wend for that loop. 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 while statement evaluates expression, which must return a boolean value. If I say You need Begin or End markers if multiple statements are required in the loop. Control then returns to the While statement and condition is checked again. Remarks. Note: The important point to note when using while loop is that we need to use increment or decrement statement inside while loop so that the loop variable gets changed on each iteration, and at some point condition returns false. PRINT "Press any key to continue" WHILE INKEY$ = "" WEND. The control statement is a combination of some conditions that direct the body of the loop to execute until the specified condition becomes false. If < condition 1 > Then statements Else If < condition 2 > Then statements Else If < condition 3 > Then statements Else Statements End If End If EndIf. While...Wend loop is similar to Do While loop though not used commonly. This label may be in or outside the control of the While statement. The loop in this example uses a for loop to collect the car names from the cars array: The general syntax as follows for bash while loop: while [condition ] do command1 command2 commandN done. The purpose of the loop is to repeat the same code a number of times.
