Nested Loops

• Here is the pseudocode:

  print table header
  double rate;
  for (rate = RATE_MIN; rate <= RATE_MAX; 
       rate = rate + RATE_INCR)
  {
     print table row
  }
  

• How do we print a table row? You need to program another loop.

  int year;
  for (year = YEAR_MIN; year <= YEAR_MAX;
       year = year + YEAR_INCR)
  {
     balance = future_value(initial_balance, rate, year);
     cout << setw(10) << balance;
  }
  

• It's a good idea to print the table header as a loop as well.

  cout << "Rate     ";
  int year;
  for (year = YEAR_MIN; year <= YEAR_MAX;
       year = year + YEAR_INCR)
  {
     cout << setw(2) << year << " years";
  }
  

• Once everything is put together, you have the loop printing a single row nested in the loop that traverses the interest rates.
