       ten numbers should display on a line. You will have to choose some
       way to output a newline after every tenth number.
       There are several different ways to count! 
         a. Create a counter variable. Add one to it each time you
            output an number. Using a decision structure, if you
            reach 10 output a newline and start your count over.
         or
         b. In a decision structure, use modulus to see if you have
            reached a number evenly divisible by 10
       Your output should look similar to this
