The do while loop is also called an exit condition loop in c, c++, and java.
The break statement is used to exit a loop or switch-case.
An entry control loop places the conditional expression that terminates the loop at the start of the loop, where it is evaluated before each iteration of the loop. If the expression initially evaluates false, then the loop does not iterate at all and control passes to the next statement following the loop. An exit control loop places the conditional expression at the end of the loop, where it is evaluated after each iteration of the loop. This means that the loop always iterates at least once. Generally, exit control loops are best avoided as conditional expressions are ideally placed up front where they can be seen. This helps make code easier to read and thus easier to maintain. However, there will inevitably be cases where an exit control loop helps to express the logic more clearly. In C there are 3 ways to define a structured iterative loop, using the for, while and do-while statements. Although for and while loops are entry control loops and do-while is an exit control loop, conditional expressions may also be placed anywhere in the body of the loop itself, thus it is possible for a loop to be both entry control and exit control. However, to aid readability and maintainability, it is best to place the conditional expression up front whenever possible.
while loop and for loop are entry controlled loops as they check looping condition at the entry point. do while loop is exit controlled loop as it checks looping condition at exit point. shreeradha@yahoo.com
In short, a for loop declares an variable and assigns it a value, has an argument, and has an update. A while loop only has an argument. More Detail... in C++, which is very close to C an example while loop is; while(i
In C a structure within a structure is called nested. For example, you can embed a while loop in another while loop or for loop in a for loop or an if statement in another if statement.
Available.
the counter variable cannot be initialized in while loop before entering into the block.
C, for loops, while loops, and do while loops are control structures forFor example, the following programs are functionally identical: While loop

You don't need a 'trap' signal to exit the infinite loop shell - just use the interrupt signal (^C, for example). while true do echo -n Filename ': ' read aFile rm $aFile done
