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.
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.



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

Lab 9*9

Write a program to generate the following table of arithmetic expressions

Lab Fibonacci numbers

Do Project 3.3 (1st ed.) or Project 6 (2nd ed. & 3rd ed.) Fibonacci numbers.
List the first 100 numbers and the ratio of
a number to its previous number, such as 1/1 = 1, 2/1 = 2, 3/2 = 1·5, 5/3 = 1·666..., 8/5 = 1·6, 13/8 = 1·625, 21/13 = 1·61538....

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.

Lab Finding the max of three numbers

Write a program to decide the max number of the three input number.
