Looping Exercises

From WLCS

Objective:

  • To become well-learned in the way of the while loop

Resources:

Directions:

  • For each of the following sequences, first prompt the user for a number N
  • Use while loops to generate the following sequences
  • Powers of 2
    • Print out the first N terms of the sequence
    • 1, 2, 4, 8, 16, 32, 64, 128, ...
  • Fractions Sequence
    • Print out the first N terms of the sequence
    • 1/1, 1/2, 1/3, 1/4, 1/5, ...
  • Summation up to N
    • Use a loop to add up all the numbers from 1 up through N
    • Example: N = 3 would total 6
    • Example 2: N = 10 would total 55
  • Fibonacci Sequence (HINT: use multiple variables)
    • Print out the first N terms of the sequence
    • 0, 1, 1, 2, 3, 5, 8, 13, 21, ...
  • Factorial Sequence (HINT: use multiple variables)
    • Print out the first N terms of the sequence
    • 1, 1, 2, 6, 24, 120, ...
