Computer Science 1 A while loop is a form of a pre - test loop, meaning that the loop condition is testing prior to executing the loop body. The loop body statements will not executed if the looping condition is not met. 2 The loop condition is a Boolean expression, returns true or false. 3 We continue looping as long as the looping condition is true. 4 The loop condition often has a sentinel value that once is reached the looping 4 The loop condition often has a sentinel value that once is reached the looping will cease. 5 The looping condition is usually associated with a counter that is incremented within the body of the loop. 6 A while() loop does not have a closing ; semi - colon. 7 A while() loop is often used to read an unknown number of records from a text or data file. We read and continue reading as long as we not reached the e.o.f.

Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
