    step 1     Fill an array num[100] with numbers from 1 to 100
    step 2     Starting with the second entry in the array, set all its multiples to zero.
    step 3     Proceed to the next non-zero element and set all its multiples to zero.
    step 4     Repeat step 3 till you have set up the multiples of all the non-zero elements to zero
    step 5     At the conclusion of step 4, all the non-zero entries left in the array would be prime numbers, so print out these numbers.
