Here's a lil surprise for your friend (and you). Run it and see what conclusions you can draw:

 #include <iostream>
#include <string>
#include <vector>

using namespace std;

//Elementary functions(s) void requestValue();

//Optional helper function(s) void wait_for_enter();

//Elementary globals.
vector<double> theVector;
double theVal;

int main()
{
   requestValue();
   
   //Process data here.
   
   wait_for_enter();
   return 0;
}

////////////////////////////////////////////////////////////// void requestValue()
{
   cout<<"Enter the value (double precision accepted) => ";
   cin>>theVal;
   while(!cin.fail() )
   {
      theVector.push_back(theVal);
      cout<<"Enter the next value => ";
      cin>>theVal;
   }
}

////////////////////////////////////////////////////////////// void wait_for_enter()
{
  cout << "press <enter> to continue...\n";
  // Reset failstate, just in case.
  cin.clear();
  string line;
  getline( cin, line);
}

Obviously requestValue() is what your friend is interested in.
