    getline

    I'm working on an assignment and I'm trying to have the user enter a name, like this:
    Code:
        cout << "please enter this student's full name:\n>";
        cin.getline(search.name,strlength);
    This seems ok to me, but I get this error:
    lab4.cpp:185: invalid conversion from `int (*)(char*)' to `int'
    lab4.cpp:185: initializing argument 2 of `std::basic_istream<_CharT,
    _Traits>& std::basic_istream<_CharT, _Traits>::getline(_CharT*, int) [with
    _CharT = char, _Traits = std::char_traits<char>]'
    185 is the getline line, and strlength is a global const int. I'm using gcc on a redhat linux 9, does anybody know what might be causing this?

    Make the name member a std::string and use
    Code:
    std::cin >> search.name;
    This is why it's always best to use the standard, it makes a lot of tasks easier.

    Isn't the syntax for cin.getline
    cin.getline( *buffer_name, int_length, "charTOstopAT") as in:
    Code:
    cin.getline( *buffer, 256 , '\n' )
    ?

    You should probably show more code, like the declaration of search.name and strlength, as well as what headers you are including. Also, I assume you are using g++ to compile.

    This code seems to work just fine:
    Code:
    #include <iostream>
    using namespace std;
    
    const int strlength = 80;
    
    int main()
    {
        char name[strlength];
        cout << "please enter this student's full name:\n>";
        cin.getline(name,strlength);
    }
    Incidentally, the standard string version of that code is this:
    Code:
    #include <iostream>
    #include <string>
    
    int main()
    {
        std::string name;
        std::cout << "please enter this student's full name:\n>";
        std::getline(std::cin, name);
    }

    Nope! haha I'm an idiot, g++ compiles it just fine.
