12. Iteration (while loop)

• The world's first "real program" running on a stored-program computer (David Wheeler, Cambridge, May 6, 1949)

  
  // calculate and print a table of squares 0-99:
  int main()
  {
      int i = 0;
      while ( i < 100 ) {
          cout << i << '\t' << square( i ) << '\n';
          ++i ;    // increment i
      }
  }
  
  

  • No, it wasn't actually written in C++ :-)
