While loops and for loops in flowcharts when code is generated for a flowchart rational rhapsody recognizes flowchart elements that represent while loops and generates the appropriate code.

While loops are a way we can easily represent a process that includes many repeated steps. There are various ways of preparing structured flowchart like by using condition case or for loop. Only then the test expression is evaluated. For starters this flowchart will help you.

C for loop syntax. You will understand it once we see some programs. When you look at the flowchart you can see that we loop through a command as long as or while a condition is true. Flowchart example for repeat loop.
