what is the deference between for,while and do while loop

Answer 1

For and while loops are equivalent (though they have a different synthax), but you should generally use a for loop when you know how many times you will loop, and a while loop otherwise.

With a do while loop, you are garanteed to loop at least once as the condition is checked at the end of the loop rather than at the beginning like in a for or while loop.

Answer 2

Do while works at least once.
" While" loop works only if the condition of it is true.

Answer 3

while loop means like: "while this is happening, do this "

for loops means: "for this to happen, do this "
do while loop means:"do this, while this is happening "

i hope that kinda helps :)

Answer 4

do while loop will run once even if the condition is false but in case of for & while loop condition should be true to run the loop.

for loop is used when you know the number of times the loop will run & while is used when you don't know how many times the loop will run

Answer 5

tnx

Answer 6

For is the easy way

And while is same but it checks before run
Do while is opposite
