Do While Loop In Flowgorithm

When the expression is false the loop ends. Loops within a method we can alter the flow of control using either conditionals or loops. Then the test expression is evaluated again.

A computer program does this by having a loop that adds or multiplies each successive value onto the accumulator.

Do while loop in flowgorithm. Function main declare integer start declare integer stop declare integer increment assign start getvalue starting assign stop getvalue ending assign increment getvalue increment call whileloop start stop increment call doloop start stop increment call forloop start stop increment end function getvalue string name declare integer value output enter name value input value return integer value function whileloop integer start integer stop integer. To visualize how this works try adding some numbers in your head say 12 7 9 and 10. This process goes on until the test expression is false. The while loop and the do loop are two powerful concepts that allow your program to do the same task multiple times.

If the test expression is true codes inside the body of while loop is evaluated. The loop statements while do while and for allow us execute a statement s over and over. Like a conditional a loop is controlled by a boolean expression that determines how many times the statement is executed. While shape default appearance.

A while loop evaluates a boolean expression and then if true executes a block of statements. Example the example to the right shows a do statement that accepts only a valid age as input. This svg file uses embedded text that can be easily translated using a text editor. After the statements are executed the while statementt rechecks the expression.

The while loop evaluates the test expression. When the test expression is false while loop is terminated. However these are not the only loop structures that professional programmers use on a regular basis. A do loop is similar to a while loop except that the block of statements is executed at least once before the expression is checked.

There is a third structure called the for loop. The source code of this svg is valid. This vector image was created with an unknown svg tool. Flowgorithm while loop flowchart.

How while loop works. The example to the right prints the numbers from 1 to 100. Counting loops and accumulators page 3 an accumulator is a variable that the program uses to calculate a sum or product of a series of values.
