If you want to use more than one character, you have to use an array of characters (also known as a string).

#include <iostream> 
using namespace std; 

int main(void) 
{ 
   char userName[21]; // Lets you have up to 21 characters for a name.

   cout << "Please insert your name" << endl; 
   cin >> userName; 

   cout << "Hello and welcome " << userName << " to this really lame program" 
}

What if they supply more than 20 characters (null terminator!)?

Easier and safer to use a string:

#include <iostream>
#include <string>

using namespace std; 

int main() 
{ 
   string userName;

   cout << "Name? >" << flush;
   getline(cin, userName); // get everything until the newline

   cout << endl;

   cout << "Hello and welcome " << userName << " to this really lame program" << endl;
}
