    Inputing multiple characters...

    Here is my startout text RPG:

    Code:
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
        char charname;
        cout<<"Welcome to Tri-Dungeon RPG\n";
        cout<<"Please name your character: ";
        cin>> charname;
        cin.ignore();
        cout<<"Your character is named "<< charname <<"\n";
        cin.get();}
    But the thing is, when i input A or 3 it doesn't crash. It works. But when i enter multiple characters it crashes, how can you input multiple characters without it crashing? Thx for ur help.

    A char holds a single character. To hold multiple characters, you use a string. In C++, you #include <string> and use the string class. So instead of char, give the name variable the type string.

    BTW, that will only read in a single word. If you want to allow spaces in the name, you will have to use another function called getline, which reads the entire line input by the user including spaces.

    thanks for the info.
    But for some reason getline isn't working... Do you have to add another library? If so, what is it?
    It should be:

    Code:
    #include <iostream>
    #include <string>
    
    using namespace std;
    
    int main()
    {
        getline charname;
        cout<<"Welcome to Tri-Dungeon RPG\n";
        cout<<"Please name your character: ";
        cin>> charname;
        cin.ignore();
        cout<<"Your character is named "<< charname <<"\n";
        cin.get();}

    getline is a function, string is the type. It should be string charname.

    You don't need to use getline. If you just use string above, then it will work and you can read in one name (without spaces).

    After you get that working, if you want to read in a name with spaces, then you change cin >> charname to getline(cin, charname) because getline does input like cin >>.
