question about loops

Have you ever bothered writing those 2 loops ? I bet you have not. Your question can be clarified using only the names of the loops: Do While and While Do(usually called the while loop).

1. Do While - Do *something* while *this is true*

do
{
   //what's here
}
while(/*this is true*/)

2. While Do - While *this is true* Do *something*

while(/*this is true*/)
{
   //do what's here
}

In the Do While loop, first the loop body is executed and then the condition is checked.

In the While (or While Do as you called) loop, first the condition is checked and then runs the body loop.

Do While:

The do while loop executes the content of the loop once before checking the condition of the while.

Procedure goes like this:
. Run the code in the body of the loop.
2. Check the condition. If it's true, go to step 1. Otherwise, move on.



While:
A while loop will check the condition first before executing the content.

Procedure goes like this:
1. Check the condition. If it's true, go to step 2. Otherwise, move on.
2. Run the code in the body of the loop.
3. Go to step 1.
