// C Primer Plus
// Chapter 9 Exercise 3

// Write a function that takes three arguments: a character and two integers.
// The character is to be printed. The first integer specifies the number of
// times that the character is to be printed on a line, and the second integer
// specifies the number of lines that are to be printed. Write a program that
// makes use of this function.
