Homework 5-19-2008

1. Do Temperature Project, which is Project 7 (3rd, 2nd ed.) or Project 3 (1st ed.).

Average income by gender

Write a program to calculate average income by gender based on the following data, where F stands for female and M for male.

F 62,000
M 25,000
F 38,000
F 43,000
M 65,000
M 120,000
F 80,000
M 30,100

You should be able to allow users to type in a whole line such as F 80,000 followed by next line M 30,100.

Without any change made to your program, your program should be able to process a new set of data, such as follows:

M 52,000
M 35,000
F 48,000
M 33,000
F 75,000
F 110,000
F 90,000
M 30,100

Homework 3-24-2008

1. Based on your study of Display 3.8, write a code to find the max and min of a list of number.
For example, given 1,3,5, and9, the max is 9 and the min is 1.
Your program should be able to process a list of any length.

2. Write a program to generate the series 1, 1, 2, 3, 5, 8, 13, ...
The series has a property that the third number is the sum of the first and second numbers. For example, 2=1+1, 3=1+2, and 5=2+3.

Do Project 5 of Chap. 1 on Page 56.

Write a program that starts with a line of text and then outputs that line of text with the first occurrence of "hate" changed to "love". For example, a possible sample output might be

The line of text to be changed is:
I hate you.
I have rephrased that line to read:
I love you.

Hint: You may consider use the methods: indexOf(A_String) and substring(Start, End) in your program.
