    [RESOLVED] C++ Class Military to Standard Time

    basically my program lets the user inputs military time( in hour, minute, and seconds). I need to convert this to standard time and have am/pm at the end. Here is what I have so far.

    I have a 3 files, time.h, time.cpp (defines functions), and main.cpp (testing). I have a problem in my main function under main.cpp. I don't understand how to set the parameters of the two time objects; t and test. When i do test( hr, min, sec) it shows random numbers when it prints out in standard time.

    Can someone help me! Thanks.

    (HEADER FILE called Time.h)

    #ifndef TIME_H
    #define TIME_H

    class Time
    {
    public:
    Time(int=0, int=0, int=0);
    ~Time();
    int hour; // valid values are 0 to 23
    int minute; // valid values are 0 to 59
    int second; // valid values are 0 to 59
    void setTime( int, int, int ); // function that checks if inputs are valid
    void printUniversal(); // prints in HH:MM:SS format
    void printStandard(); // prints in HH:MM:SS AM/PM format
    static int count; //counter
    };

    #endif

    ------------------------------------------------------------------------------------------------------

    (File that contains definitions- Time.cpp)

    #include <iostream>
    #include <iomanip>
    #include <ctime>
    #include "Time.h" //header file that contains the Time class file
    using namespace std;

    int Time::count = 10;

    Time::Time(int hr, int min, int sec)
    {
    hour = hr; minute = min; second = sec;
    count++;
    }


    Time::~Time()
    {
    count--;
    }

    void Time::setTime( int hr, int min, int sec )
    {
    hour = ( hr >= 0 && hr < 24 ) ? hr : 0; // checks if hour input is valid
    minute = ( min >= 0 && min < 60 ) ? min : 0; // checks if minute input is valid
    second = ( sec >= 0 && sec < 60 ) ? sec : 0; // checks if seconds input is valid
    }

    void Time:rintStandard()
    {
    cout << ( ( hour == 0 || hour == 12 ) ? 12 : hour &#37; 12 ) << ":"
    << setfill( '0' ) << setw( 2 ) << minute << ":" << setw( 2 )
    << second << ( hour < 12 ? " AM" : " PM" )<< sizeof(Time);
    }


    void Time:rintUniversal()
    {
    cout << setfill( '0' ) << setw( 2 ) << hour << ":"
    << setw( 2 ) << minute << ":" << setw( 2 ) << second;
    }


    ---------------------------------------------------------------------------------------------------------------

    (Where I implement the functions- main.cpp)

    #include <iostream>
    using namespace std;
    #include "Time.h"


    int main()
    {
    int hour, minute, second;

    Time t(); //t is the time object //(PROBLEM!!!-Dont understand how to write the correct parameters)
    Time test(); //test is also a time object //(PROBLEM!!!-Dont understand how to write the correct parameters)
    //Time *tp = new Time;
    //Time *tarray = new Time[5];



    cout << "Enter hour in military time ";
    cin >> hour;
    cout << "Enter minute ";
    cin >> minute;
    cout << "Enter second ";
    cin >> second;



    cout << "\nThe standard time is ";
    t.printStandard(); //(PROBLEM!!!- I have the number 12 appearing right after AM and i can't get rid of it. )
    cout << "The universal time is ";
    test.printUniversal();
    cout << endl;
    return 0;
    } // end main

    Thanks VictorN for replying.

    I was able to figure out the parameters and get rid of the 12 (due to the unnecessary sizeof(Time)). I made a very silly mistake and was calling the function before inputting variables.
