while-loop

A while loop within bash allows you to execute a statement a given number of times, or until a certain condition is met.

At this point, the break statement causes program execution to break out of the while loop, skipping the else clause.

With a while loop set up to read from stdin, the various components of the dots file are extracted.

When you want a group of activities to run multiple times, until some condition no longer holds true, you can use a while loop activity.

The developers who originally created the 11-page while loop had left the company by the time we had to clean it up.

The routing between the general step (with no name) and While Loop contains logic that corresponds with the loop condition.

Double clicking on the while activity in the editor enables you to see the sub flow inside the while loop.

Each time through the while loop, the next row in the resulting data set is accessed until the last row is reached.

Once you understand the if statement, the while loop is fairly simple to understand, as well.

The upper half of this figure shows the three modeling elements to represent a while loop, a do-while loop, and a for loop.

The WHILE-LOOP associates a condition with a sequence of statements enclosed by the keywords LOOP and END LOOP, as shown in Listing 7.

A Java do loop is similar to the Java while loop, except that the while test happens at the bottom of the loop.

Modifying the condition of a While loop, when the instruction pointer is in the condition.

A while loop then iterates through the dataset, storing the information in a convenient array for later display.

BuildCanary then goes back to the top of its while loop and waits for the next message.

Both threads increment a variable in a while loop and run for a set time.

At the bottom of the while loop, you read another directory entry and process it.

In this example, the code in the body of the do. While loop is executed until the variable quit is true.

The while loop is a perfect example to close with, as it combines a loop with a condition.

And " Discover Python, Part 5" introduces the concept of compound statements in Python, and the if statement and the while loop.

A while loop will rarely include the number of iterations -- unless it is a for loop in disguise.

If you clicked to expand a while loop, the editor showed just the contents of the while loop.

With improved phase estimation method, a carrier signal phase with phase noise can be estimated, while loop SNR also increases.

A while loop is a loop that repeats the included activities while some condition is satisfied.

The controlling expression of an if statement or while loop evaluates to a constant.

The system task named While Loop points to an activity set that contains tasks corresponding to the ones in the while loop (Figure 12).

Some models are decomposed into multiple levels, such as a While loop within a local subprocess, within a While loop.

In this way, the FileNet process acts in the same manner as a while loop, even though loops are not supported.

Thus you need to wait until you're finished parsing the document (you've broken out of the while loop).

Instead, the program enters a while loop waiting for new connections.

When the condition evaluates to false, the loop terminates and the next activity after the while loop runs.

Until then, the function blocks in a while loop.

Normally, functional languages eschew the while loop, because most of what while does can be done instead with recursion.

The while loop is used to iterate over this small number of properties and process the appropriate member on object .

Listing 5 shows an example of an SQL procedure with a WHILE loop.

The %MACRO_FUNCTION of Listing 4 shows six insert statements executed 40 times using a while loop.

If the expression evaluates to false, execution continues at the first statement after the do-while loop.

The WHILE loop scans the input array; when an element begins with the required area code, it is added to the output array.

Notice how this method accounts for possible weak references in the queue with the do-while loop.

The following code processes elements by using a While loop.

The while-loop-condition is evaluated before each iteration of the loop.

The diagram for the while loop is shown in Figure 6.

Exit While can be used only inside a While loop.

Substep 3-2 is to run a while loop for each item in the list.

Unlike the while statement, a do-while loop is executed once before the conditional expression is evaluated.

This method then waits in a continuous while loop that is periodically interrupted at the desired PWM switching frequency.

The obvious issue is that the NULL check must be part of the while loop.

We'll diagram the while loop shown in Listing 3.

This starts the second trip through the while loop, where the variable i becomes 25.

The while loop has three major pattern-matching sections.

The contents of the new while loop are expanded for view.

Figure 6 shows the contents of the while loop (Manufacturing Loop).

With capture kicked off and your captureProbe set to the default value, you will always enter your while loop.

The output from the "while" loop appears similar to the following.

If you want to fiddle with counters, use the while loop instead.

The while loop in Listing 12 ensures that spurious wake-ups are handled properly.

Based on the instance state when the while loop completes, the appropriate branch will be taken, and thus the correct e-mail will be sent.

Note the use of recursion to avoid the while loop entirely.

Decrement the count and end the while loop.

Figure 7 shows the visual flow and Figure 8 drills down to illustrate the flow inside the while loop.

While loop because the strong reference keeps it from being garbage collected.

Going a step further, look at the structure of the code inside the while loop.

For this purpose, I have used a do-while loop that continues dividing the value integer by 256 until the value drops below 1.

The while loop is used when you want the loop to execute and continue executing while the specified condition is true.

Listing 8 shows an example of using an iterating WHILE-LOOP.

Obviously, since this is a snapshot in time, the line could be any line inside the while loop, such as line 16, 17, or 18.

To see that the program gives the correct answer, you need to look at the condition in the while loop

The while loop (like the for loop introduced later in this article) supports three additional statements

(Generally, though, you would have these hosts in a text file and read them in using a while loop. )
