  • *****Exercise 4.1 Generate a multiplication table

    Recommendation:

    Exercise 4-1. Write a program that will generate a multiplication table of a size entered
    by the user. a table of size 4, for instance, would have four rows and four columns. the
    rows and columns would be labeled from 1 to 4. each cell in the table will contain the
    product of the corresponding row and column numbers, so the value in the position
    corresponding to the third row and the fourth column would contain 12.
