We have used filestream in c++ to write data to files. I have completed the steps asked in comment form and final code is given below.

#include <iostream>
// To use files 
#include<fstream>
using namespace std;
int main()
{
        int choice;
        int biden = 0, trump = 0, bugs = 0;
        int vc = 0;
//      declare file_stream and open auditTrail.txt in append mode
        fstream auditTrail_file;
        auditTrail_file.open("auditTrail.txt", ios::out | ios::app | ios::in);
        fstream tally_file;
        do {
                cout << "\n\n\nEVOTE\n-----" <<
                        "\n1.Joe Biden" <<
                        "\n2.Donald Trump" <<
                        "\n3.Bugs Bunny"
                        // 4. Print current tally[hidden admin option]
                        // 5. Print audit trail[hidden admin option]
                        // 6. mess with the vote[hidden hacker option] E.C.
                        // 7. END THE ELECTION
                        <<
                        "\n\n Your selection? ";
                cin >> choice;
                if (choice == 1)
                {
                        biden++;
                        vc++;
                        cout << "\nThanks for voting!";
                }

                if (choice == 2)
                {
                        trump++;
                        vc++;
                        cout << "\nThanks for voting!";
                }

                if (choice == 3)
                {
                        bugs++;
                        vc++;
                        cout << "\nThanks for voting!";
                }
        
                if ((choice < 1) || (choice > 7)) cout << "\nPlease enter 1-3";
                
                
                // write what happened to FILES
                // Tally.txt (overwrite) biden x trump x bugs x
        //open in truncate mode everytime to overwrite previous content
                tally_file.open("Tally.txt", ios::out | ios::trunc | ios::in);
                tally_file<<biden<<" "<<trump<<" "<<bugs;
                tally_file.close();
                // auditTrail.txt ios::app (everything typed) 1 2 3 3 56 -12 4
        //append user input to auditTrail_file 
                auditTrail_file<<choice<<" ";
        } while (choice != 7);

        cout << "\n\nRESULTS:\n--------" <<
                "\nTotal Votes Cast This Election: " << vc <<
                "\nJoe Biden: " << biden <<
                "\nDonald Trump: " << trump <<
                "\nBugs Bunny: " << bugs;

        cout << "\n\n";
        system("pause");        // leave this out if using newer DEV C++
        return 0;
}

Sample Output:

Tally.txt after it : 2 3 0

auditTrail.txt: 1 2 2 2 1 7
