C++ Help With Prog Closing

I just started C++ coding about 2 days ago and I'm using a book. Its a great book and I have made scripts with it but with 1 major problem. Whenever I run my prog it instantly closes. The book said if I encountered this problem I should use

Code:

cout << "Press the enter key to exit the program!" << endl;
    cin.ignore(cin.rdbuf()->in_avail()+1);

But this won't work in situations where I have to press the enter key to accept something in a script. I am currently making this script

Code:

#include <iostream>
#include <string>

using std::cout;
using std::cin;
using std::endl;
using std::string;

int main()
{
    const int GOLD_PIECES = 900;
    int adventurers, killed, survivors;
    string leader;
    
// Get the information
    cout << "Welcome to Lost Fortune\n\n";
    cout << "Please enter the following for your personalized adventure\n";
    
    cout << "Enter a number: ";
    cin >> adventurers;
    
    cout << "Enter a number, smaller than the first: ";
    cin >> killed;
    
    survivors = adventurers - killed;
    
    cout << "Enter your last name: ";
    cin >> leader; 
    // Tell the story
    cout << "\nA brave group of " << adventurers << " set out on a quest ";
    cout << "-- in search of the lost treasure of the Ancient Dwarves. ";
    cout << "The group was led by that legendary rouge, " << leader << ".\n";
    
    cout << "\nAlong the way, a band of marauding ogres ambushed the party! ";
    cout << "All fought bravely under the command of " << leader;
    cout << ", and the ogres were defeated, but at a cost. ";
    cout << "of the adventurerers. " << killed << " were vanquished, ";
    cout << "leaving just " << survivors << " in the group.\n";
    
    cout << "\nThe party was about to give up all hope. ";
    cout << "But while laying the deceased to rest, ";
    cout << "they stumbled upon the buried fortune. ";
    cout << "So the adventurers split " << GOLD_PIECES << " gold pieces.";
    cout << leader << " held on to the extra " << (GOLD_PIECES % survivors);
    cout << " pieces to keep things fair of course.\n";
    
    cout << "\n\n\n\nPress the enter key to exit the program!" << endl;
    
    return 0;
}

What should I do to keep the program from exiting??

Thanks,

add this above the "return 0;"

Code:

int nothing;
cin>>nothing;

Use this before return 0.

Code:

cin.ignore();
cin.get();

ignore() extracts the special enter character from the stream, and get() requests a character. This would not work if more than one character was in the stream (somewhat rare in tests, or little projects). You could use cin.ignore(256,' '); to be almost sure, or use <climits> to be accurate, in that case.

Thanks!
