This loop allows using three statements first is the counter initialization next is the condition to check it and then there is an increment decrement operation to change the counter variable.

Flowchart do while loop example. The purpose of a while loop is to execute a statement or code block repeatedly as long as an expression is true. Syntax of do while loop. The while loop the most basic loop in javascript is the while loop which would be discussed in this chapter. If the test expression is evaluated to false the while loop terminates.

C for loop syntax. Initially i 1 test expression i number is true and factorial becomes 1. C for loop flowchart. If an action or decision node has an exit transition with a guard as well as a second exit transition and there is also a transition that brings the flow back to the original decision point ibm rational rhapsody recognizes that these elements represent a while loop and generates the appropriate code.

For starters this flowchart will help you. Variable i is updated to 2 test expression is true factorial becomes 2. While i 5 console writeline c for loop. Here is a simple example of how a while loop works.

Here s how while loop works. Once the expression becomes false the loop terminates. You will understand it once we see some programs. The body of the loop is executed at least once because the condition test follows the body.
