Programming Assignment 4 Assignment Overview

This assignment will give you more experience on the use of lists and files.

Part 1:  Name Search [75 points]

Write a program that reads the contents of the following two files into two separate lists. 

 GirlNames.txt – This file contains a list of the 200 most popular names given to girls born

in the United States from the year 2000 through 2009. 

 BoyNames.txt – This file contains a list of the 200 most popular names given to boys born

in the United States from the year 2000 through 2009.

The user should be able to enter a boy’s name, a girl’s name, or both, and the application will

display messages indicating whether the names were among the most popular. 

Here is a sample run of the program:

Enter a boy’s name, or N if you do not wish to enter a boy’s name: Jacob

Enter a girl’s name, or N if you do not wish to enter a girl’s name: Amal

Jacob is one of the most popular boy’s names.

Amal is not one of the most popular boy’s names.

Part 2: Population Data

The file USPopulation.txt contains the midyear population of the United States, in thousands,

during the years 1950 through 1990. The first line in the file contains the population for 1950,

the second line contains the population for 1951, and so forth.

 Write a program that reads the file’s contents into a list. The program should display the

following data: 

 The average annual change in population during the time period

 The year with the greatest increase in population during the time period

 The year with the smallest increase in population during the time period

Here is a sample run of the program:

The average annual change in population during the time period is 2,443.88

The year with the greatest increase in population was 1955

The year with the smallest increase in population was 1967
