Here is the data:

Classes/Streams Marketing software In this p rogramming assignment, you identify the number of potential customers for a business. The starter program outputs the number of potential customers in a u age range serentored given a file with people's data. Move the dass Person to the separate files: person, h and personucpp. Make sure you can stil with separate files. 2 During file reading, the program isntstonng the gender or yearty noome of the people, Instead, the defa values are being printed. F ix the program to correctly set the date read from The regions of the code that need to be ed are marked with: "FIXME Also set gender and yearly income" 3 Allow the user to select the potential customers gender: male". female' ar any. The program should now output potential customers with the user-spected gender and age. Update the GetUserinput tuncton to prompt the user and store the user's gender selection ate a function GetPeopleWithSpecificGender that returns only people with the user-pacitad gender. Debugging suggestion: Use a function to pnnt main's vector of Persons so that you can see who is in the vector after eachfunction cal. This techniqu may help debug the newly created function GetPeopleWithSpecificGender in addition to age and gender, alow the user to select the ower and upper range of a austomer's yearly income, Update the GetUserinput function to prompt the nd store th ser's specified range. Also, create a function GetPeoplelnincomeRange that retums only people with the user specifed yearly income.
