The do..while Loop

The general format is as follows :

                do

{

                                statements;

                                :

                                :

                 }             while(condition);

e.g.

                do

                 {

                                cout << x;

                 }             while( x < = 10);

The do.. while loop is exactly like while loop, with single difference. Here testing is done after implementing the statements inside the loop and if the condition evaluates to true then we enter the loop again ,while in while only after the expression is checked we enter the loop.  We can say do loop is implemented at least once.
