Combining Random Gen/ Text file

[Wi3ard]

What I am trying to figure out how to combine the text file I created and the Random Gen/Array



#include <iostream>
#include <iomanip>
#include <string>
#include <ctime>
#include<fstream>

void displayLargestNum();
void appendRandomNum(string);
void exit();
void CreateFile();
void printFunc(int[]);
void fillFunc(int[]);

int main()
{
menu();
string FileName;
//createFile();
//makeRandomNum();

system("pause");
return 0;
}

{
int choice;
