  1. In Topic: I have a Date class how can I make two of it's function work prope

    Posted 30 Apr 2012

    I figured out that function, but do you have any suggestion for this function.
    I think my if statements are not coded well that is why it is not working specially for the month of februar and for the leap years.
    [void Date::SetDate(int requestedyear, int month, int day )
{
     if (requestedyear < 0)
     {
        cout<<"Sorry we do not have data for this year.";
        return;
     }

    else
        year = requestedyear;



    if (month > 12 || month < 0 )
    {
        cout<<"Invalid month entry."<<endl;

    }

        numOfmonth = month;



    if (month ==2)
    {
        if(year%400==0&&year%4==0)
    {
        if (numOfmonth = 2)
        {
            numOfday = 29;
        }

    }

    else if(year%100)
    {
        if (numOfmonth == 2 && numOfday == 29)
        {
            --numOfday;
        }

    }
    else if (day > 28)
        cout << " Invalid day entry for month of February.";

    }
    else if (month == 9 || month == 4 || month == 6 || month == 11 )
    {
        if (day > 30)
        cout << " Invalid day entry.";

    }
    if ( day > 31 )
    cout<<"Invalid day entry."<<endl;

        else
        numOfday = day;

}
]

    Adanceoneday function does not have argument I could not pass the argument of the AdvanceDays to the Advanceonedays if you have any suggestions I would be very glade.

    This should be obvious to you if you think about it.

    Suppose you have a button and each time you press the button it rings a bell 1 time. What would you do if you want to ring the bell 3 times?

    It is sample I should press it three times but I think it not the case. Do you mean I should call the function three times. 
    [void Date::AdvanceDays(int n)
{
    Date da;
    da.AdvanceOneDay(); //if I pass n in the Advanceongday function it gives me an error. 
}
]

    Right now I am testing my code but two functions are not working properly;

    Why are they not working properly? Ask specific questions.

    I think my if statements are not coded well that is why it is not working 
    [void Date::SetDate(int requestedyear, int month, int day )
{
     if (requestedyear < 0)

        return;
     }

    else
        year = requestedyear;



    if (month > 12 || month < 0 )
    {
        cout<<"Invalid month entry."<<endl;

    }

        numOfmonth = month;



    if (month ==2)
    {
        if(year%400==0&&year%4==0)
    {
        if (numOfmonth = 2)
        {
            numOfday = 29;
        }

    }

    else if(year%100)
    {
        if (numOfmonth == 2 && numOfday == 29)
        {
            --numOfday;
        }

    }
    else if (day > 28)
        cout << " Invalid day entry for month of February.";

    }
    else if (month == 9 || month == 4 || month == 6 || month == 11 )
    {
        if (day > 30)
        cout << " Invalid day entry.";

    }
    if ( day > 31 )
    cout<<"Invalid day entry."<<endl;

        else
        numOfday = day;

}

    Since you know in advance of compile time that all you are 'tracking' is words with length 1 to 10 characters long ...

    you could just use an array of 10 int's initialed to 0

    int word_len[ 11 ] = { 0 } ; // not going to use index 0

    Then all you need is something like this:
    cout << "Enter a word ('END' to end) : " << flush;
while( cin >> word && word != "END" )
{
   if( word.size() && word.size() < 11 )
      ++word_len[ word.size() ];
   cout << "Enter a word ('END' to end) : " << flush;
}

    thank you very much it helped me a lot.

    Create a vector containing 10 zeros. Then instead of writing an if for every number between 1 and 10, simply check that the number is between 1 and 10 and then increase the number in the vector at the appropriate index (i.e. if the entered number is 1, increase the_vector[0], if it is 2, increase the_vector[1] etc. - clearly you don't need if statements for that).

    Thanks for your reply, could you please give me some more explanations.
    this is the mean assignment
    Write a program that reads in a list of words from the user until the user enters the word “END”.
    Then, display a list of word lengths, from 1 to 10, and how many words of each length were entered.
    For instance, after the user had typed 20 words, the output might look something like:
    Length 1 words: 2
    Length 2 words: 3
    Length 3 words: 5
    Length 4 words: 6
    Length 5 words: 3
    Length 6 words: 2
