Can we use if statement in while loop?
And to answer your questions, yes it’s perfectly valid to nest if statements in a while loop.
Why is if loop used?
An if statement is a good choice here because it allows us to control which statement is printed depending on which outcome occurs. Our if statement’s condition should be an expression that evaluates to TRUE or FALSE . If the expression returns TRUE, then the program will execute all code between the brackets { } .
Which type of loop is while loop?
While Loop is a type of loop that is used when you don’t know exactly how many times the code will repeat. It’s based on a condition, so the instruction inside the while should be either a boolean value (True/False) or an operator that returns a boolean (<,>,==, etc.).
What is the difference between for and while loop?
Two of them are for and while loop. The difference between for and while loop is that the for loop is used when the number of iterations is known and the while loop is used when the number of iterations is not known.
Why are while loops useful?
“while loops” execute blocks of code over and over again.
What is while and for loop?
The for loop is a repetition control structure that allows the programmer to efficiently write a loop that needs to execute a specific number of times. The while loop is a repetition control structure that executes target statements as long as the given condition is true. The for loop can be used when the number of iterations is known.
What is an example of while loop?
A while loop is a control flow structure which repeatedly executes a block of code indefinite no. of times until the given condition becomes false. For example, say, you want to count the occurrence of odd numbers in a range. Some technical references call it a pre-test loop as it checks the condition before every iteration.
