thanks in advance

Create a program that takes a number and counts how many times it can be divided by 2 before it is smaller than 1. You will need to create a single int variable and stores a number in it that will be used and a second int variable as a counter. Then you will use a While loop and the counter to count how many times it divides (Don't forget to make the 2 a 2.0 when you divide). Finally print both the original number and the number of times it divided in a suer friendly format (as in make a sentance saying what each number you print is). The print statement MUST use the 2 variables or no credit will be awarded.
