After the cin>>this number; the '\n' remains in the stream and is picked
by the next cin.get(). If you want to pause you must enter 2 cin.get():

#include <iostream>

int main()
{
 using namespace std;
  
 int thisisanumber;
 
 cout<<"Please enter a number:";
 cin>>thisisanumber;
 cin.get();
 
 cout<<"You entered: "<<thisisanumber;
 cin.get();

 return 0;
}
