use vectors to read a file and then print info.

[hamzams25]

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 person’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 user’s menu similar to the one below:
Enter person’s information:
Print out person’s information
Exit

If user selects “1”, the program will search person’s last name, and if found, will print out person’s information. (Search for Clinton, Trump, Obama). If not found, output a message indicate the person’s information is not found. (search Bush)


If user selects “2”, the program will print out all the person’s information have entered so far (which is stored in a vector). After prints out all the person’s information, the program will print out the menu again and waiting for user’s input.
If user selects “3”, 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

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.

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

[jacobP]

This is a forum to help with Qt issues, not a place to have other do your school assignments for you...

Start by breaking down the work you have to do :

-Have your program load the .txt correctly
-Have your program read the .txt correctly
-Once you know you read the file correctly, construct the person objects with the info you read from the file. By the looks of it your person.cpp is in very bad shape. Start by fixing that and making sure your Person class has all it's member correctly functioning before worrying about vectors.

Once all that is done, you will have easy-to-handle objects with all the info needed and writing the code that handles the user input will be much easier to think about.
