What is while loop ?

It is a loop and also known as entry controlled loop. While loop first test the conditions, when the conditions are true than body of the loop (block of statements associated with loop) is executed and the condition is rechecked by increment or decrement in conditional values. This process is repeated until the condition become false, when the condition is false than execution of the program will jump to the next statement.

while  (condition)

{

                ……………..

                ……………..

}
