String Counter

I'm trying to get the program to print the string in one solid line and show how many strings are in the line, its for a study program im working on that will end up comparing the users answer to the stored answer. If anyone has any tips or advice it would be greatly apppreciated.

The code, so people don't have to download it themselves:

Code:

#include <cstdlib>
#include <iostream>
#include <string>

using namespace std;

int main(int argc, char *argv[])
{
    int nos = 0;   // Number of strings
    int nsc = 0;   // Number  of strings counted
    
    string nui = "";  // Collection of all strings
    ++nsc; // When a string is added to nui add 1 to nsc
    
    string ui;     // Users input
    cout << "Type something" << endl;   
    
    while ((nos > nsc) && ui += nui)    // While nos > nsc and ui has another word to add to the nui
    {                                   // continue checking for new strings in ui if ui += nui it partialy works.
          cin >> ui;                    // Users Input
          ++nos;                        // add +1 to nos for each word input
          ui += nui;                    // add new word to nui
    }
    // Print out the results
    cout << "You typed - " << nui << " - and it had - " << nsc << " - words in it." << endl;
    
    system("PAUSE");
    return EXIT_SUCCESS;
}

Vague questions rarely get good answers.
