Do While Loop C Flowchart

Do while loop is a variant of while loopwhere the condition isn t checked at the top but at the end of the loop known as exit controlled loop. If the test expression is true codes inside the body of while loop is evaluated. It is similar to a while loop however there is a major difference between them.

Then the test expression is evaluated again.

Do while loop c flowchart. If the test expression is false the loop ends. Only then the test expression is evaluated. While condition. If the condition is true the flow of control jumps back up to do and the statement s in the loop execute again.

The while loop evaluates the test expression. The c do while loop is executed at least once because condition is checked after loop body. Do while is also a loop in c but unlike for and while this is exit control loop or down checker loop. Unlike for and while loops which test the loop condition at the top of the loop the do while loop in c programming checks its condition at the bottom of the loop.

The do and while keyword is used to create a do while loop. The c do while loop is used to iterate a part of the program several times. If the test expression is true the body of the loop is executed again and the test expression is evaluated. Just lie for loop the while loop has three parts.

Loop will terminate when the given condition will false. In while loop the condition is checked before the body is executed. A do while loop is similar to a while loop except the fact that it is guaranteed to execute at least one time. This process goes on until the test expression is false.

The while loop is a methodology to use a piece of code again and again until the given condition remains true. In c programming loop is a process of repeating a group of statements until a certain condition is satisfied. The body of do while loop is executed once. This means statements inside do while loop are executed at least once and exits the loop when the condition becomes false or breakstatement is used.

If the number of iteration is not fixed and you must have to execute the loop at least once it is recommended to use do while loop. It is the exact opposite in do while loop i e. While condition. Condition is checked after the body is executed.

The syntax of a do while loop in c programming language is. Notice that the conditional expression appears at the end of the loop so the statement s in the loop execute once before the condition is tested. This process goes on until the test expression becomes false. It means it tests the condition at the bottom of the body or before exiting from the body.
