Then piss-poor practices won't hurt you at all. Unless they spread to other areas, of course.

(Toggle Plain Text)

getline (cin,mystring);

so effin simple.......(isnt it?)

Kilo · Nov 28th, 2005, 4:19 PM

i was told not to recommend that lol.. nothing from the conio library!

DaWei · Nov 28th, 2005, 5:05 PM

"getline" isn't from the conio library....

Ooble · Nov 28th, 2005, 5:15 PM

Is that specific getline from iostream or string?

B3TA_SCR1PT3R · Nov 28th, 2005, 5:21 PM

according to my calculation its from....iostream

Just to summarize information in this thread (:p):

std::cin stops reading the input stream when a space, or newline character is encountered.

A useful alternative to an array of chars in C++ is the std::string class.
This class can be used by including the <string> header file.

Remember that string is part of the standard library.

A useful string function is

(Toggle Plain Text)

getline(sourceOfInput, stringVariable)

and example might be:

(Toggle Plain Text)

std::cout << "Enter fullname: ";
getline(cin, name);

getline() has an optional third argument, which is char. The function will read up to (not including) that character.

this allows me to have a file like:

test.txt

(Toggle Plain Text)

bread:
cheese:
eggs:
milk:

and a getline function like this

(Toggle Plain Text)

getline(inFile, stringVariable, ':');

This is all non-working, example code.

First, sorry for my previous statment (im a little slow

)

Second, why am i having so much trouble opening a specific file by STRING???

MyCode:

(Toggle Plain Text)

cout << "file name to scan?";
getline(cin,s_fileIn,'\n');

s_fileIn.append(".txt");

FileIn.open(s_fileIn,ios_base::in);   //line 58

ERROR:

(Toggle Plain Text)

c:\Documents and Settings\knowell\Desktop\DataSearch\DataSearch\main.cpp(58): error C2664: 'void std::basic_ifstream<_Elem,_Traits>::open(const char *,std::_Iosb<_Dummy>::openmode,int)' : cannot convert parameter 1 from 'std::string' to 'const char *'
        with
        [
            _Elem=char,
            _Traits=std::char_traits<char>,
            _Dummy=int
        ]

are you wanting to get input from the user and write that to the file?, if so:
[php]
cout << "file name to scan?";
getline(cin,s_fileIn);
ofstream myfile (s_fileIn);
if (myfile.is_open())
{
getline(cin,mystring);
myfile << mystring << endl;
myfile.close();
}
else cout << "Unable to open file";
[/php]

(untested code)
