Question

I am making a command-line c++ application and I want text to be on a sort of timer because there is a lot of text. I already know how to make it so they have to press enter, but I want it to be automatic. What would be the simplest way to do this.

Example Output:

Welcome to the Calculator Game!
(1 second later) Do you want to play(Yes or No)?

The easiest thing is just to use `sleep(milliseconds)’. Most operating systems have varous ways of doing timers as well.

Even better if you are using C++11, use something like this:

#include <iostream>
#include <chrono>
#include <thread>

int main()
{
    std::cout << "Hello waiter" << std::endl;
    std::chrono::milliseconds dura( 2000 );
    std::this_thread::sleep_for( dura );
    std::cout << "Waited 2000 ms\n";
}

If you’re not using C++11, then try the following:

#include <time.h>

void sleep(unsigned int mseconds)
{
    clock_t goal = mseconds + clock();
    while (goal > clock());
}
