Chapter 15, Problem 4PC

Time Format

Program plan:

source.cpp:

• Include the required header files to the program.
• Define the “main()” function.
  • Get the hours and seconds from the user.
  • Check whether the hours is between 0 through 2359 and the seconds between 0 to 59.
  • Create an object for “MilTime” and pass the “hours” and “sec”.
  • Display the military hours using “getHour()” function.
  • Display the military hours using “getStandHr()” function.
  • Display the military hours using “getMin()” function.
  • Display the military hours using “getSec()” function.

Time.h:

• Define the “Time.h”.
  • In protected, declare the required variable.
  • In private, create the constructor by passing hours, minutes and seconds.
  • Make a call to the function “getHour()”, “getMin()” and “getSec()” to get hours, minutes and seconds.

MilTime.h

• Define the “MilTime.h”.
  • In private, declare the required variable.
  • In public, create the constructor by passing two integer arguments.
  • Declare a function “convert()” which convert the hours to military format.
  • Create a mutator function for time.
  • Create an accessor function for military hours and standard format.

MilTime.cpp:

• Define the “MilTime.h”.
  • Create a constructor “MilTime” which is derived from “Time” class.
  • Set “hrs” to “milHours”.
  • Set “sec” to milSeconds;
  • Call the function “Convert()”.
• Function definition for function “Convert()”
  • Declare a required variable “val”.
  • Check whether the “milHours” is greater than “1200”.
  • Subtract “milHours” by “1200”.
  • Divide “hours” by 100 and assign to variable “hour”.
  • Subtract “milHours” by “1200”and divide by 100.0.
  • Type cast the variable “val” to “int”.
• Function definition for function “setTime()”
  • Assign “hrs” to “milHours”.
  • Assign “sec” to “milSeconds”.
  • Call the function “convert()”.
