C/C++ :: Quiz Show Game - Reset File To Original

I've been taking a C++ class, and for a project we need to do, we have to create a simple quiz show game while putting the high scores and names inside a .txt file. We have lessons we can look at to complete it while learning. But at the end there's always a challenge that we should complete to show that we've actually learned the information. For the challenge, we needed to take the information in the .txt file and reset it to its original information. So say there's 5 people preset that have high scores, then a person plays the game and the program asks if they'd like to reset the list. If the user inputted 'y' or any key that needed to be pressed, the program would reset the .txt to its original information.

This is the code that creates the program.

// Include Libraries
#include <iostream>
#include <string>
#include <fstream>
// Include standard namespace
using namespace std;
// Declare Global Variables
int Guess;
int Winnings;

It works how I need it to and there aren't any problems, necessarily, but I want to know if there's any, more efficient, ways of completing this task. Like if there's any already made function of resetting a file.

This is the code that resets the file. As you can see, it just uses the information earlier in the code inside the if statement. Is there any pre-made function or method of resetting a file?

cout << "Would you like to reset the high scores list? (y or n): ";
cin >> ask;

if (ask == 'y')
{
High_Score[0] = 25000;
High_Score[1] = 12000;
High_Score[2] = 7500;
High_Score[3] = 4000;
High_Score[4] = 2000;
