/* Craig Persiko - CS 110A - invest.cpp
   Sample program to demonstrate constants and if-statement.

   Investment Program
   Allows user to enter the amount of an investment.
   Investments under $50,000 earn 5% interest, and investments equal to
   or above $50,000 earn 6% interest.  The dollar amount of interest
   earned is output by the program.

  // The above values are constants: they cannot be changed


  double inv_amount, int_earned;

  // Format output to show dollars and cents:

  cout.setf(ios::fixed);
  cout.setf(ios::showpoint);
  cout.precision(2);

  cout << "\nWelcome to Investment World";

  // No curly braces are needed above because only one line is

  // executed in each case.

Welcome to Investment World
