getline

[ichijoji]

I'm working on an assignment and I'm trying to have the user enter a name, like this:

    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

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:

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:

#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:

#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.
