Thread: C++ Strings with spaces

Ok, i found this that works with spaces on the FAQ:

Code:

#include <iostream>
#include <string>

int main()
{
  std::string line;

  std::cout<<"Enter a string: ";

  if ( getline ( std::cin, line ) )
    std::cout<<"You entered \""<< line <<"\""<<std::endl;
}

and it works fine, but, i wanted to use it without the std:: for this program
(Simple i know):

Code:

#include <iostream>
#include <string>
using namespace std;

string pass;
string user;

int main()
{
    cout<<"What is your username?(12 characters max): ";
    cin.getline ( user, 12, '\n' );
    cin.ignore();
    cout<<"What is your password?(12 characters max): ";
    cin.getline ( pass, 12, '\n' );
    cin.ignore();
    if (user == "The Master" && pass == "I am master")
    {
             cout<<"Access is granted.\n";
             cout<<"Press enter to end user authentication.";
             cin.get();
    }
    else
    {
    cout<<"Access denied";
    cin.get();
}
}

however when i do that, i get the following error from my compiler(Dev-C++):
11 C:\Dev-Cpp\Tutorial\Inproved user authentication.cpp no matching function for call to `std::basic_istream<char, std::char_traits<char> >::getline(std::string&, int, char)'

Along with a similar error for line 14, (The 11 is the line number).
Both these errors seem to pertain to cin.getline which of course works fine if i use C strings instead. Ok, please tell me if there is a shorter code for the strings with spaces code, and if so how to use it. Thanks

I think to save it to a string vs a char* you want to use

Code:

getline(cin,pass,'\n');

vs

Code:

cin.getline()

Ok, thanks this works perfectly:

Code:

#include <iostream>
#include <string>
using namespace std;

string pass;
string user;
std::string line;
int main()
{
    cout<<"What is your username?: ";
    getline ( cin, user, '\n' );
    cout<<"What is your password?: ";
    getline ( cin, pass, '\n' );
    if (user == "The Master" && pass == "I am master")
    {
             cout<<"Access is granted.\n";
             cout<<"Press enter to end user authentication.";
             cin.get();
    }
    else
    {
    cout<<"Access denied";
    cin.get();
}

}

Thanks alot, i'm new to programming or i probably would have figured that out by myself... well back to the tutorials lol
