for loop to while loop

Question

I am using a for loop to print the backwards alphabet in uppercase but I would like to know how to do the same thing with a while loop, which I am

Answer 1

for (initialization; condition; increment) {

}

is same as:

{
    initialization;
    while(condition) {
       // body
       increment;
    }
}

The outer block creates a block scope for the initialized parameter, that we get in a for loop also. But, if you are declaring your for-loop variable outside the loop, then you can omit that outer block.

Now you can map your for loop to the while loop.
