Which of the following is NOT true about sentinel loop? O It requires sentinel to be distinguishable from data. O It does not require user to enter in every iteration whether to continue or not. O Empty string is always the sentinel. O It does not need to know in advance how many times it will execute.
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.
