    class TIME, help please

    Okay guys, here is the class i use:

    class TIME {
    public:
    TIME();
    void AddSecond();
    void SetTime(int, int, int);
    void GetTime();
    void PrintTime();
    private:
    int hour;
    int min;
    int sec;
    };

    So i have to write console application in MVS 6, which uses this class and shows time with autoincrement each second.

    So i need to write something like this Pascal statement:

    repeat
    ....
    PrintTime;
    AddSecond;
    delay(1000);
    until keypressed.

    Can someone help me ?

    any one who have interesting solution post here or mail me to the-saint@mail.bg

    class TIME, help please

    Okay guys, here is the class i use:

    #include <string.h>
    #include <iostream.h>
    #include <stdio.h>
    #include <dos.h>
    #include <conio.h>

    class TIME {
    public:
    TIME(); // constructor
    void AddSecond(); // sec++
    void SetTime(int, int, int);
    void GetTime();
    void PrintTime();
    private:
    int hour;
    int min;
    int sec;
    };

    TIME::TIME()
    {
    hour = 0;
    min = 0;
    sec = 0;
    }

    void TIME::SetTime(int h, int m, int s)
    {
    if (h>=0 && h < 24) { hour = h; }
    if (m>=0 && m < 60) { min = m; }
    if (s>=0 && s < 60) { sec = s;}
    }

    void TIME::GetTime()
    {
    cout << "Enter Time in 24-hr format: ";
    cout << "\n hour: ";
    cin >> hour;
    cout << "\n min: ";
    cin >> min;
    cout << "\n sec: ";
    cin >> sec;
    if ((hour<0) || (hour >23) || (min<0) ||
    (min>59) || (sec<0) || (sec>59))
    {
    cout << "\nError detected!\n" ;
    }
    }

    void TIME::PrintTime()
    {
    cout << (hour<10?"0":"") << hour << ":"
    << (min <10?"0":"") << min << ":"
    << (sec <10?"0":"") << sec << endl;
    }

    void TIME::AddSecond()
    {
    if (sec == 59)
    {
    sec = 0;
    if (min == 59)
    {
    min = 0;
    if (hour == 23)
    hour = 0;
    else
    hour++;
    }
    else
    min++;
    }
    else
    sec++;
    }

    int main()
    {
    char ch[2];
    // main program
    TIME t;
    t.GetTime();
    do
    {
    t.PrintTime();
    t.AddSecond();
    scanf("%c", ch);
    }
    while ( 1 != 0);
    return 0;
    }

    So i have to write console application in MVS 6, which uses this class and shows time with autoincrement each second.

    So i need to write something like this Pascal statement:

    repeat
    ....
    PrintTime;
    AddSecond;

    >Can someone help me ?

    With what ? What exactly is your question ? What is the part your are having problems with ? I could not access your code, got a 404. Does it compile ? Does it run ? Does it produce the desired result ?

    When in doubt, read the FAQ.
    Then ask a smart question.

    I think your class could do with some work.

    GetTime() gets from keyboard and enters whatever was got into class private members with scant regard for limits. ok if it detects an error you get a message but thats it. You should check the values before they are stored in the class private members. Only stroe if correct.
    SetTime() has a similar problem. If time out of bounds it is ignored rather than either an exception being thrown or a default value (say 0) being entered instead both of which are preferable to ignorance.
    Free the weed!! Class B to class C is not good enough!!
