C++ How do to have the program sleep for a few seconds???

Question

I tried doing Sleep(3000) but it doesn't work and #include<windows.h> isn't allowed

Answer 1

OnlineGDB is hosted on Linux not windows so need to use #include <unistd.h>, which is the Linux header file equivalent to windows.h

Answer 2

You could use while and/or for loop. You could even use <time.h> to propperly check time per clock or seconds passed. An example, is to create a function containing this instructions.

Answer 3

it is not that hard all you have to do is to use the <windows.h> as your header file and wherever you want it to sleep you have to use the function Sleep(time in miliseconds);

An example:-

#include <windows.h>
#include<iostream>

using namespace std;

int main()
{
    cout<<"hello this text will change after a pause of 10 seconds"<<endl;
    Sleep(10000);
    cout<<"this is the new text"<<endl;

   return 0;
}

welcome in advance :)

Answer 4

Though C code works in C++, I'd suggest checking out the C++ library and have a look at std::this_thread::sleep_for().

#include <iostream>
#include <unistd.h> // PUT IT CODE

using namespace std;

int motor ;

int main()
{
    cout<<"type ON TO START 3 MOTORS"<<  "\n";
    cin >> motor ;
    
    sleep(2)  ; // SLEEP 3 SECONDS.
    
    cout << " ON  motor 1 " <<  "\n";
    sleep(2)  ;
    
    cout << " ON motor 2 " <<  "\n";
    sleep(2)  ;
    
    cout << " ON motor 3 " <<  "\n";
    sleep(2)  ;
    
    cout << " ALL ON AND Ok " <<  "\n";
    sleep(2)  ;


    return 0;
