use vectors to read a file and then print info.

Hi, I have written part of this code but I am having trouble with some things that I dont know are missing. The requirement of the code is below:

Your program must include the following:
Implement all the class methods defined above
Must initialize the class object variable with initial value in the default constructor
Your program will read a file contains personâ€™s info. The file has the following format:

FirstName LastName Sex BirthYear BirthMonth BirthDay

The file name must (sample file: personsInfo.txt personsInfo.txt) be passed in when you start the program using argc, argv: main (int argc, char* argv[])
After reading the file, your program will have an userâ€™s menu similar to the one below:
Enter personâ€™s information:
Print out personâ€™s information
Exit

If user selects â€œ1â€, the program will search personâ€™s last name, and if found, will print out personâ€™s information. (Search for Clinton, Trump, Obama). If not found, output a message indicate the personâ€™s information is not found. (search Bush)

If user selects â€œ2â€, the program will print out all the personâ€™s information have entered so far (which is stored in a vector). After prints out all the personâ€™s information, the program will print out the menu again and waiting for userâ€™s input.
If user selects â€œ3â€, the program will exit. Class: Class section name (CS-106-02 or CS-106-03) Your program submission:
Pdf file contains all of the following:

What I have so far is below. I would appreciate it if you guys could help me understand and finish the code.

PersonInfo.txt

Code:

Hillary Clinton F 1947 10 26
Donald Trump M 1946 06 14
Bernie Sanders M 1941 09 08
Barack Obama M 1961 08 04
Melania Trump F 1970 04 26
Michelle Obama F 1964 01 17

Okay so after working on the program and trying my best to fix all compiler issues I got to my best but I am having trouble on how I read my file using a vector in the program, and also what I need in some of the functions in the person.cpp file.

Attaching code below:

Pleae guide on how to fix it.

Code:

#include <cctype>
#include <iostream>
#include <vector>
#include <string>
#include "Person.h"
using namespace std;
 
void printMeFirst();
 
void promptUserForInput( vector<Person> &people )
{
    string firstName;
    /*string lname;
    string sex;
    int byear;
    int bmth;
    int bday;*/
 
    cout << "Enter the first name: ";
    cin >> ws;
    getline( std::cin , firstName );
 
    while( !isalpha(firstName[0]) ) 
    {
        cout << "Invalid Name!\n"
             << "Re-enter your name: ";
        getline( std::cin , firstName );
    }
   }
 
void printInformation(const vector<Person> &people)
{
    for( const auto &person : people ) 
    {
        person.printPerson();
    }
}
 
 
int main(int argc, char *argv[])
{
	printMeFirst();
 
	std::vector<Person> people;
    int choice = 0;
 
     while( people.size() < 30 && choice != 3 ) 
     {
        std::cout << "Menu\n\n";
        std::cout << "1. Enter Personal Information\n"
                  << "2. Print personal information\n"
                  << "3. Exit\n"
                  << "Enter your choice: ";
        std::cin >> choice;
 
 
        if( choice == 1 ) 
        {
            promptUserForInput( people );
        }
        else if( choice == 2 ) 
        {
            printInformation( people );
        }
        else if( choice == 3) 
        {
            std::cout << "\nGoodBye";
        }
        else 
        {
            std::cout << "\nInvalid Choice\n";
        }
    }
 
	if (argc != 2 )
	{
	    std::cout << "usage " << argv[0] << " fname\n";
	    return 1;
	}
	else
	{
	    std::cout << "The program will print the follwoing data " << argc << " as entered\n";
	    std::cout << "The name enter was " << argv[0] << std::endl;
            std::cout << "The info is " << argv[1] << std::endl;
	}

the FILE that i have to make the program read is in the original post at the very top. Take a look at that
