Launching a Script from C++

Question

What I want to do is create a program to prompt the user for input. If they select yes I want to terminate the rest of the program. If they select no I want to immediately run a script. If there is no input for 5 minutes I want the script to automatically run. The only reason I want to use the script or batch file is I previously created it and it is already done.

The problems I am having is I am not sure how to declare the file system and file so it can be called. Then, I am not sure how to call the script to run. I am also not sure how to count down the 5 minutes to auto launch the script when ready. Below is my file in all it's current form.

//Program Name Apex Database Backup
//Written 8/3/2016
#include <iostream>
#include <cstdlib>
#include <fstream>
#include <string>
#include <windows.h>
#include <stdio.h>
using namespace std;
int main()
{
    //Declarations
    bool yes;
    bool no;
    char yesOrno;
    string open;
    FILE *C$;
    //Prompt the User for Input
    cout << "Are You Currently Loading Out? If Not This Program Will Execute in 5 Minutes. " << endl;
    cout << "You Will Lose Your Connection to Apex! " << endl;
    cout << "Enter yes or no: " << endl;
    //Get User Input
    cin >> yesOrno;
    //Open the File
    public FILE *DatabaseBackup.bat fopen(*C$)
        //Process the Selection
            if (no)
            {
                ShellExecute (DatabaseBackup.bat);
            }   

    return 0;
}

A character variable only holds 1 character. The words "yes" and "no" consist of more than one character. You will either need the user to enter 'y' or 'n'; or use `std::string`. — Thomas Matthews, Aug 10 '16 at 15:09
You never initialize your Boolean variables. The statement "`if (no)`" will depend on the random value in memory. Undefined behavior, anything could happen. — Thomas Matthews, Aug 10 '16 at 15:11
Why write a program for this? Can't you just use `read -p "Do you want to cancel?" -N 1 -t 300"` (or the equivalent for your shell) in your script? — Toby Speight, Aug 10 '16 at 15:58

I'm not sure what you mean by "declare the file system". If you want to open a file, take a look at C++ File IO

Then, I am not sure how to call the script to run

Running the script is a OS related function. See this answer on how to do this.

I am also not sure how to count down the 5 minutes to auto launch the script when ready.

You need to use a timer/clock with a signal/interrupt.
