Question about multi-word strings

Hey I am learning C++ from the book "C++ Primer Plus" and I am on an exercise that has me write a program to write a program to ask from a persons full name(has to be able to handle names with 2 words), age, and what grade they think they earned. The program then will print out the name, age, and the grade that is one letter lower. My entire code is this.

Code:

---

#include <iostream>
#include <string>


struct info
{


    std::string first;
    std::string last;
    int age;
    char grade;
};


int main()
{


    using namespace std;
    info student;


    cout<< "What is your first name? ";
    getline(cin, student.first);
    cout<< "What is your last name? ";
    getline(cin, student.last);
    cout<< "What letter grade do you deserve(A-C only)? ";
    cin >> student.grade;
    cout<< "What is your age? ";
    cin >> student.age;


    student.grade = char(int(student.grade) + 1);


    cout<< "Name: " << student.last << ", " << student.first << endl;
    cout<< "Age: " << student.age << endl;
    cout<< "Grade: " << student.grade << endl;
    return 0;
}

What I was wondering is there a "more correct" way to get a multi word string as input besides this?

Code:

---

getline(cin, student.first);

---

It is working for what I need to but I just do not want to develop any habits that later I will have to change.

Also another thing that I was wondering is there an better way to firgure out the final grade is besides this?

Code:

---

student.grade = char(int(student.grade) + 1);

---

If there is anything else you notice that is worth mentioning, I would be extremly thankful for anyone who would point it out.

getline is the proper way to get a line of input (that may contain spaces).

Since a char is just a small number, you should be able to just do student.grade++;

Heck,
student.grade = student.grade + 1
or
student.grade += 1
should also work.

Thanks for answering those two questions but I have one more if you have a char variable will always be treated as an interger value if its on the right side of the "="?

Depends on context, but it is an integer and can be treated as such.

ok so basically what I did is handled automatically by the compiler in this case? Think I understand this better now. Thanks.

A char is just an integer, usually one byte, possibly signed. It is only treated specially on input and output.

Does the compiler also store things like strings as a number or is this just something for characters?

A C-style string is an array of chars, i.e. numbers, ending in a zero. The C++ string class also contains an array of chars.

Oh ok Thanks for all the help. I have been learning from a book so its nice to be able to ask someone the questions about stuff the book either didnt cover or concepts I just didnt get(like pointers..... grr dont like those).
