****Assignment

Classes/Streams - Marketing software

In this programming assignment, youll identify the number of potential customers for a business. The starter program outputs the number of potential customers in a userentered age range given a file with peoples data.

1. Move the class Person to the separate files: person.h and person.cpp. Make sure you can still compile with separate files.

2. During file reading, the program isnt storing the gender or yearly income of the people. Instead, the default values are being printed. Fix the program to correctly set the data read from file.

The regions of the code that need to be fixed are marked with: FIXME Also set gender and yearly income

3. Allow the user to select the potential customers gender: male, female, or any. The program should now output only potential customers with the userspecified gender and age.

Update the GetUserInput function to prompt the user and store the users gender selection.

Also, create a function GetPeopleWithSpecificGender that returns only people with the userspecified gender.

Debugging suggestion: Use a function to print mains vector of Persons so that you can see who is in the vector after each function call. This technique may help debug the newly created function GetPeopleWithSpecificGender.

4. In addition to age and gender, allow the user to select the lower and upper range of a customers yearly income.

Update the GetUserInput function to prompt the user and store the users specified range. Also, create a function GetPeopleInIncomeRange that returns only people with the userspecified

yearly income.

The main should now look like the following code:

intmain(intargc,char*argv[]){ vectorpeople; boolhadError=false; intageLowerRange=0; intageUpperRange=0; stringgender=""; intyILowerRange=0; intyIUpperRange=0;

hadError=ReadPeopleFromFile(argc,argv,people); if(hadError){

return1;//indicateserror }

GetUserInput(ageLowerRange,ageUpperRange,gender,yILowerRange, yIUpperRange);

people=GetPeopleInAgeRange(people,ageLowerRange,ageUpperRange); people=GetPeopleWithSpecificGender(people,gender); people=GetPeopleInIncomeRange(people,yILowerRange,yIUpperRange);

cout<<" Numberofpotentialcustomers="<

return0; }

Here is an example program execution with people.txt (user input is highlighted here for clarity):

Openingfilepeople.txt. Age=20,gender=male,yearlyincome=25000 Age=25,gender=male,yearlyincome=45000 Age=23,gender=male,yearlyincome=30000 Age=16,gender=male,yearlyincome=7000 Age=30,gender=male,yearlyincome=55000 Age=22,gender=female,yearlyincome=27000 Age=26,gender=female,yearlyincome=44000 Age=21,gender=female,yearlyincome=37000 Age=18,gender=female,yearlyincome=17000 Age=29,gender=female,yearlyincome=62000
