Type of Loop in C Programminig

Type of Loop

We can classify the loop into two categories. They are:

1].    Pre-Tested Loop: When the control statement is placed at the beginning/top of the loop body is called Pre-Tested or Entry Controlled loop.

These types of loop first check the given condition then execute the body of a loop.

  

Counter=Start Value

Loop(condition)

{

            Statement 1

. . . . . . . . .

Statement N

Counter Update

}

Example: - for loop, while loop

           

2].    Post-Tested Loop: When the control statement is placed at the end/bottom of the loop body is called Post-Tested or Exit Controlled loop.

This type of loop first executes the body of a loop then check the given condition.

Counter=Start Value

Loop

{

                  Statement 1

                  . . . . . . . . .

Statement N

Counter Update

 } (condition)

Example: - do…while loop

 The execution of loop includes the following four steps:

1].    Initialize the loop variable.

2].    Test the condition using loop variable with the end value.

3].    Execute the statements within the loop body.

4].    Update the loop variable.
