What is false loop?

A while loop checks the condition (well, the expression) behind the while before each iteration and stops executing the loop body when the condition is False . So while False means that the loop body will never execute.

Whats the difference between a loop and a while loop?

For loop vs While loop The difference between for loop and while loop is that in for loop the number of iterations to be done is already known and is used to obtain a certain result whereas in while loop the command runs until a certain condition is reached and the statement is proved to be false.

What is difference between Do and loop?

A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement….Here is the difference table:

while	do-while
while loop is entry controlled loop.	do-while loop is exit controlled loop.

What is difference between while loop and do while loop and for loop?

The loop iterates while the condition is true. When the condition becomes false, the program control passes to the line immediately following the loop….Output.

While Loop	Do-While Loop
The while loop may run zero or more times	Do-While may run more than one times but at least once.

Do-While and while loop are same true and false?

Explanation: do-while loop is exit controlled loop whereas while loopis an entry controlled loop.

Which statement is false about while loop?

while loop is a posttest loop and the limit condition is checked at the end of each execution of the loop. Hence option ‘e’ is also false.

What is the difference between while loop and for loop in Python?

for loops is used when you have definite itteration (the number of iterations is known). while loop is an indefinite itteration that is used when a loop repeats unkown number of times and end when some condition is met.

What is the difference between while loop and do-while loop in Java?

The while loop in java executes one or more statements after testing the loop continuation condition at the start of each iteration. Therefore, the do-while loop guarantees one execution of the loop logic whereas the while does not. …

What is the difference between for and while loop in Python with example?

What is the difference between for loop and while loop in Javascript?

while — loops through a block of code once; then the condition is evaluated. If the condition is true, the statement is repeated as long as the specified condition is true. for — loops through a block of code until the counter reaches a specified number.
