Pascal has two forms of the while loop, while and repeat. While repeats one statement (unless enclosed in a begin-end block) as long as the condition is true. The repeat statement repetitively executes a block of one or more statements through an until statement and continues repeating unless the condition is false. The main difference between ...
Additionally, in C# if a block consists of only a single statement, the braces may be omitted. C# is case sensitive while Visual Basic .NET is not. Thus in C# it is possible to have two variables with the same apparent name, for example variable1 and Variable1. Visual Studio will correct (make uniform) the case of variables as they are typed in ...
end – one more than the index of last element in the slice len – the length of the slice (= end - first) step – the number of array elements in each (default 1)
Generally, it may be put only between digit characters. It cannot be put at the beginning (_121) or the end of the value (121_ or 121.05_), next to the decimal in floating point values (10_.0), next to the exponent character (1.1e_1), or next to the type specifier (10_f).
A possible variant is to allow more than one while test; within the loop, but the use of exitwhen (see next section) appears to cover this case better. In Ada, the above loop construct (loop-while-repeat) can be represented using a standard infinite loop (loop - end loop) that has an exit when clause in the middle (not to be confused with the ...
However, infinite loops can sometimes be used purposely, often with an exit from the loop built into the loop implementation for every computer language, but many share the same basic structure and/or concept. The While loop and the For loop are the two most common types of conditional loops in most programming languages.
This API is a part of .NET Framework 3.0. A Windows Forms application is an event-driven application supported by Microsoft's .NET Framework.Unlike a batch program, it spends most of its time simply waiting for the user to do something, such as fill in a text box or click a button.
However a while loop will test the condition before the code within the block is executed. This means that the code is always executed first and then the expression or test condition is evaluated. This process is repeated as long as the expression evaluates to true. If the expression is false the loop terminates. A while loop sets the truth of ...
