    Functions and Creating Files

    Im working on a project that is supposed to let the user enter a title and some text and the program is supposed to create the file and then give the user the option to view it, i am very lost at the moment and any help would be great

    void CreateText(void);

    int main()
    const int Max=80;
    char filename[Max]="c:\Text1.dat";
    char text[Max]="c:\Text1.dat";
    void CreateText(void);


    void CreateText(char filename[],char text[])
    char Text1;
    ofstream Text1_file;;
    cout<<" Enter the Title of the File.";
    cout<<" Enter the Text of the File.";
    return 0;

    It's pretty straightforward, just open an output file. If it doesn't exist then the program will attempt to create it.
    #include <iostream>
    #include <fstream>
    #include <string>
    using namespace std;
    int main() 
      char ch;
      string fileName, fileContents;
      ifstream readFile;
      ofstream writeFile;
      cout<<"Enter a file to create (ex. somefile.txt): ";
      getline ( cin, fileName ); ( fileName.c_str() );
      if ( writeFile.good () ) {
        cout<<"File opened\nEnter a string to place in the file: ";
        getline ( cin, fileContents );
        cout<<"Would you like to view the file? (y/n): ";
        if ( ( ch = cin.get() ) == 'y' ) {
 ( fileName.c_str() );
          getline ( readFile, fileContents );
        else if ( ch == 'n' )
          cout<<"Have a nice day!\n";
          cout<<"Invalid input\n";
        cerr<<"File could not be opened\n";
      return 0;
    My best code is written with the delete key.

    Prelude's code is excellent.

    For those using Borland:

    #include <conio.h>


    add a getch(); statement preceding return 0; at the end of main().

    (Just in case you want to play with it...)

    Some may not be aware...
