6. Problems with procedural approach

• However,

  • Program contains too many small steps.

  • Program requires up to 4 variables to handle each date: month, day, year, and serial_date.

  • No protection of any kind exists to prohibit illegal date modifications:

  
          int month = 2;
          int day = 31;    // the day is outside of allowable range for February
          int year = 2010;
