What loop would work best to write and complete the bullets below?
- Initializes a variable number=200;
- Initializes a variable count=0;
- Subtracts an integer of your choice from number to get the new number during each step of the loop, until number is less than 10.
- Updates count to keep track of how many steps are needed.

If the number of iterations is known in advance, use a FOR loop.
If the number of iterations is not known in advance, but determines by dynamic calculations, use a WHILE loop.
"until number is less than 10" sounds clearly like the number of iterations is determined dynamically.
