description of what I need done (taken from assignment instructions):
"3. Allow the user to select the potential customer’s 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 user’s gender selection.
Also, create a function GetPeopleWithSpecificGender that returns only people with the
user­specified gender.
Debugging suggestion: Use a function to print main’s 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
customer’s yearly income.
Update the GetUserInput function to prompt the user and store the user’s 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[]){
vector<Person>people;
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<<"\nNumberofpotentialcustomers="<<people.size()<<endl;
return0;
}"
(sorry if the above code pasted badly, i'm too lazy to fix all the spaces, blame whoever made the pdf)
"Here is an example program execution with people.txt (user input is highlighted here for clarity):
