  3. cin
#include <iostream>
using std::cin;
using std::cout;
using std::endl;

int main()
{
   int widthValue = 4;
   char sentence[ 10 ];

   cout << "Enter a sentence:" << endl;
   cin.width( 5 );

   cin >> sentence;
   cout << sentence << endl;

   return 0;
}

Enter a sentence:
This is a sentence.
