    Please Help?

    Okay. So I'm pretty new to C++ Programming, and my class I'm taking isn't teaching the material well enough for me to understand. Well, for this, I have written code for a game show program that outputs its high scores to a .txt file (called High_Scores.txt). I need to write another program with two for ( ) loops that re-writes to the high score document, and reset the high scores with the user's input. I have no idea how to do this. Could you guys please help me out, or point me in the right direction? The only requirement it has is that it needs two for ( ) loops, and resets the high score document. Here is my code for the quiz show program:

    Code:
    /* 
    
     
    
    The Great Quiz Show Game 
    
     
    
                by 
    
     
    
             Your Name 
    
     
    
    */ 
    
     
    
    // Include the libraries 
    
    #include <iostream> 
    
    #include <string> 
    
    #include <fstream> 
    
     
    
    //Use the standard namespace 
    
    using namespace std; 
    
     
    
    // Declare global variables 
    
    int Guess; 
    
    int Winnings; 
    
     
    
    //Define the Question class 
    
    class Question 
    
    { 
    
    private: 
    
       string Question_Text; 
    
       string Answer_1; 
    
       string Answer_2; 
    
       string Answer_3; 
    
       string Answer_4; 
    
       int Correct_Answer; 
    
       int Prize_Amount; // How much the question is worth 
    
    public: 
    
       void setValues (string, string, string, string, string, int, int);

       ifstream Input_High_Scores;
       Input_High_Scores.open("High_Scores.txt");
    
       for (int i = 0; i < 5; i++)
       {
    		Input_High_Scores >> High_Score[i];
    		Input_High_Scores >> High_Score_Name[i];
       }
       Input_High_Scores.close ();
    
    if (High_Score[4] == 0)
    {
    
    	   //Initialize local variables

    What do you mean "you don't know how to reset the table".

    You already have all the bits you need.

    > //Initialize local variables
    and
    > // Output the high scores to a file
    are the essential bits.

    On a code presentation note, double-spacing the entire file makes it pretty unreadable.

    Oh, and choose a decent topic title
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Okay. Thank you for the info. And sorry about the double-spacing and all. I'm new to the site, and that's how I write my code until it's complete.
