    My program works but only one problem...

    http://rapidshare.de/files/17827852/awesome.rar.html

    1. scroll down and click FREE

    2. download it

    3. extract anywhere

    4. run it

    5. specify the file type and contents

    6. come back here.



    As you have noticed, it does not allow spaces. I don't know what could be wrong...


    Code:
    #include <fstream>
    #include <iostream>
    #include <string>
    
    using namespace std;
    
    string fileName;
    string fileCont;
    
    using namespace std;
    
    int main()
    {
    cout<<"What filename should we use? ";
    cin>>fileName;
    cin.ignore();
    cin.get();
    cout<<"What content should we statch into the file? ";
    cin>>fileCont;
    cin.ignore();
    ofstream file (fileName.c_str());
    file<<fileCont;
    cin.get();
    return 0;
    }

    Any help would be greatly appreciated.


    Never mind the double using namespace std; 's, it was an error.

    cin >> reads until the next space.

    use
    Code:
    getline(method, targetvariable, delimiter);
    
    // method = cin, by example
    // targetvariable = variable to store input
    // delimiter(optional) = '\n' or another cstring character.

    When I use that it works perfectly, but when I remove cin.ignore() and cin.get() it doesn't show anything in the file.


    And when I don't I need to hit enter three times.

    Leave cin.ignore() after each use of cin>> (e.g. the filename), but don't use cin.ignore() after a call to getline (e.g. the file content). The ignore() ignores the trailing newline from when the user types an answer and hits enter, but getline automatically ignores that newline for you, so you only want to call ignore() explicitly after cin >>.

    Then, add a cin.get() to the end of your program to keep it open.
