Using code from standard library to stop output from exiting in Turbo C++

Question

Many of folks here are telling me to stop using clrscr(), getch() etc. and I have started learning C++ with the standard library and now that I want to follow the standard library how would I stop the output from immediate exit after run?

include <iostream.h>
include <conio.h> // Instead of using this

    void main(){
        cout << "Hello World!" << endl;
        getch(); // Instead of using this
        }

Answer 1

Just replace getch() with cin.get() like this:

include <iostream>

using namespace std;

void main()
{
    cout << "Hello World!" << endl;
    cin.get();
}

For more details see get() function documentation. Just for reference you may do this, for example, to wait until user pressed a specific character:

void main()
{
    cout << "Hello World!" << endl;
    cout << "Press Q to quit." << endl;
    cin.ignore(numeric_limits<streamsize>::max(), 'Q');
}
