Exercise 8-1: Print a checkerboard (8-by-8 grid). Each square should be 5-by-3 characters wide. A 2-by-2 example follows : +-----+-----+ +-----+-----+ +-----+-----+ Exercise 8-2: The total resistance of n resistors in parallel is: 1 / R = 1 / R 1 + 1 / R 2 + 1 / R 3 + ... + 1 / R n Suppose we have a network of two resistors with the values 400 and 200 . Our equation would be: 1 / R = 1 / R 1 + 1 / R 2 Substituting in the value of the resistors we get: 1 / R = 1 / 400 + 1 / 200 1 / R = 3 / 400 R = 400 / 3 So the total resistance of our two-resistor network is 133.3 . Write a program to compute the total resistance for any number of parallel resistors. Exercise 8-3: Write a program to average n numbers . Exercise 8-4: Write a program to print out the multiplication table. Exercise 8-5: Write a program that reads a character and prints out whether it is a vowel or a consonant. Exercise 8-6: Write a program that converts numbers to words. Example: 895 results in "eight nine five." Exercise 8-7: The number 85 is said "eighty-five," not "eight five." Modify the previous program to handle the numbers 0-100 so all numbers come out as we really say them. For example, 13 is "thirteen," and 100 is "one hundred." |
