How to Format a Calendar Program

[raiiiny]

I'm having some trouble with my Calendar program. Everything for the most part is working correctly, except I'm not sure how to make it so the calendar isn't so spaced out when it is outputted to the user. I'm currently using \t to space it all out correctly but it doesn't look exactly like how my professor would like it to look...

Just as a disclaimer: I'm relatively new to programming so a lot of things that I've done, probably don't make any sense, or my professor wants it to be that way.

// Calendar
/* This program stores a calendar month of dates (numbers starting at 1) in a two-dimensional array.
Some months have 31 days, others 30, and February has 28 (29 if it’s a leap year, which is a year divisible by 4). */

it doesn't look exactly like how my professor would like it to look

Are we expected to know what that means? Do you think we know who your professor is, and how he wants your output look?

[raiiiny]

I'm sorry mikeyboy you don't have to get so irritated. I simply would like an alternative to using \t....sorry I didn't ask that question exactly up to your standards.

Hey,

Sounds like you could use <iomanip>, setw() seems to be a viable alternative to \t if I understand it correctly: http://www.cplusplus.com/reference/iomanip/setw/

[MikeyBoy]

I'm sorry mikeyboy you don't have to get so irritated. I simply would like an alternative to using \t....sorry I didn't ask that question exactly up to your standards.

*Shrug* we can't read your mind. We can't possibly know what it is you're actually looking for if you don't tell us. Believe it or not, I was helping you, by trying to elicit more information from you about what you're looking for,

And hey, guess what - the moment you actually did that, someone was able to help you get what you want. Amazing how that works, huh?

So, this has been a productive thread for you - that's two things you've learned, for the price of one :)

Use std::setw() to set the width? http://en.cppreference.com/w/cpp/io/manip/setw

Something like this, perhaps (haven;t looked at the rest of the program):

void showCal(string choice, int GET_YEAR, int month[][col], int rows, int dayNumber[], string monthName [], string GET_DAY)
{
    int days;
    int numDays = 0;
    int start_day = 0;

    const int width = 4 ; // *** added ****

    // cout << "\t" << choice << "\t" << GET_YEAR << endl;
    cout << setw(width*3) << choice << setw(width*2) << GET_YEAR << "\n\n" ; // ****

    cout << "  Sun Mon Tue Wed Thu Fri Sat\n" ; // **** added

    for (int count = 0; count < SIZE; count++)
    {
        if (choice == monthName[count])
        {
            numDays += days_in_month[count];
        }
    }
    for (int c = 0; c < 7; c++)
    {
        if (GET_DAY == dayOfWeek[c])
        {
            start_day += dayNumber[c];
        }
    }
    //this loop sets the position for the starting day

    for (int i = 0; i < start_day; i++)
    {
        // cout << "\t";
        cout << setw(width) << ' ' ; // *****
    }
    //This loop displays the days
    for (month[rows][col] = (1+start_day); month[rows][col] <= (numDays+start_day); month[rows][col]++)
    {
        // cout << (month[rows][col]-start_day) << "\t";
        cout << setw(width) << month[rows][col]-start_day ; // *****
        if( month[rows][col]%7 == 0)
        {
            cout << endl;

        }
    }

    cout << endl;
}

This is the internet, you will find all kinds of people. Just ignore the boors.

I got it! I tried using setw() earlier but I was adding it in the wrong place! Haha
Thank you for your help JLBorges!
