Can any loop that is written as a for loop be written as a while loop?

Question

I am talking about C#, I don't know if that matters or not.

Answer 1

yes... as the previous answerers said... but

there are reasons to use for instead of while!

first is remembering that this is a finite loop (aid to the programmer)

second is for can be optimized to use registers for the variable 'i', depending on what is in the loop, this can change the behavior form chunk chunk chunk to whizzzzzz.

third, the c language for statement can do a lot more than the normal (set;test;increment)... it's very cool and can easily be used instead of while.... even if you aren't incrementing by a number!

Answer 2

Yes but a for loop runs for a finite number of times whilst a while loop runs for an infinite number of times - often relying on an event to stop it

Answer 3

No difference4. They both use counters.

Only differnce is, you might forget the counter in a while loop, since it isnt required.

The For loop requires the counter to be defined when it is declared, and wont compile otherwise, so your less apt to make an endless loop.

Answer 4

Yes, but then it will be called a for while loop... X

Answer 5

yes you can, but if you'll need to create a counter variable and use that in the while statement

Answer 6

ya u can but the thing is that you have to give the increment/decrement operation at the ending stage of the while means........

for(i=0; i<50; i++)
{..........
........
.......}

instead you have to do is to.......
while(i<50)
{..........
.........
.........
i=i+1;
}

something like that.....
