DO-WHILE
========
Syntax:
	initialization;
	do
	{
		statement-1;
		statement-2;
		update;
	}
	while(condition);


while:
=====
initialization
while(condition)
{
	statements;
	update;
}

loop entry control ==> while
loop exit control ==> do-while

class DoWhileLoop{
    public static void main(String[] args)
    {
        // initialization for do while
        int i = 10;
        do{
            System.out.println(i);
            --i;
        }while(i >= 1);
    }

Assignment:
===========
1) WAP TO CHECK WHETHER THE GIVEN NUMBER IS PALINDROME NUMBER OR NOT.
HINT:
	if(reverse == number)
		palindrome
	else
		not a palindrome
2) WAP TO COUNT THE NUMBER OF DIGITS OF A NUMBER USING DO-WHILE
