Exercises
1. Write a program to generate and display a table of n and n2, for integer values of n ranging from 1 through 10. Be sure to print the appropriate column headings.
2. A triangular number can also be generated for any integer value of n by this formula:
triangularNumber = n (n + 1) / 2
For example, the 10th triangular number, 55, can be calculated by substituting 10 as the value for n into the previous formula. Write a program that generates a table of triangular numbers using the previous formula. Have the program generate every fifth triangular number between 5 and 50 (that is, 5, 10, 15, ..., 50).
3. The factorial of an integer n, written n!, is the product of the consecutive integers 1 through n.
