Combining Two Strings into One Variable in C++

Question

I am en process of writing a simple program that assigns given student names into groups of whatever interval requested. Currently, I am focusing on the function that reads the name of the students. Here is the code:

class student
{
public:
    string nameFirst;
    string nameLast;
};

student typeName()
{
    student foo;
    cout << "Type in a student's first name: ";
    cin >> foo.nameFirst;
    cout << "Type in that student's last name: ";
    cin >> foo.nameLast;
    cout << "\n";
    return foo;
}

Since I cannot use getline(), I am forced to create two strings, one for each section of the student's full name. How can I rewrite this code to allow for it to take the full name without creating two variables and without using getline()? Or, if such isn't possible, how can I use a method within the class to combine the two strings into one?

Using >> as you have, parsing stops when whitespace is encountered, so any names with spaces will be truncated. If you don't care, then you can recombine the words into a single name with nameFirst + ' ' + nameLast. Otherwise, you may want to use e.g. get() to read into a character array until a newline is encountered (a poor imitation of getline(), so you can handle surnames like "Von Muellerhoff". More generally, to learn what std::strings can do, see en.cppreference.com/w/cpp/string/basic_string — Tony Delroy

There's also iterators: foo.name.assign(istreambuf_iterator<char>(cin.rdbuf()), istreambuf_iterator<char>()); (as apposed to the preferred std::getline() of course). — David G

You can just use

cin >> foo.nameFirst >> foo.nameLast;

cin >> will parse stops at white spaces, so you can just input the full name in one line split by space like James Bond.

To combine two strings into one:

string fullName = foo.nameFirst + " " + foo.nameLast;
