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 :)
