while loop

 

1.while Loop:

One of the most used loop statements in programming is the while statement. While a specific condition is true, the while statement instructs the compiler to repeat the series of statements. The computer stops repeating the condition as soon as it turns false and moves on to the next sentence.

                            

The condition is stated at the top of this loop. Prior to processing the while body, the while statement tests the expression's value. The while body is then executed by the computer. One or more statements may be included in the while body. There is no need for a bracket if the statement is a single sentence. Brackets are required when there are multiple statements.
