ignoring '/' when inputed by user

I'm writing code that involves people putting in dates... They must use month/day format (2 digits each... 02/01)... My output is suppose to determine what Zodiac sign they fall under.

I know I'm doing it the long way with if/else if statements, but I don't know another way.

My problem is that the user MUST according to the assignment enter the '/' between numbers. my program wants to divide... I've tried to used

Code:

cin.ignore(/)

, but that doesn't seem work... I need to be able to grab the first 2 digits and last 2 into a variable. Is

Code:

cin.get

the answer? If so, what do I put in paren to grab those numbers?

One way is to use streams:

Code:

int Month;
int Day;
char Dummy;
std::cin >> Month >> Dummy >> Day;

The / will be read into the dummy variable.
This method will NOT make any difference on 2 and 02 though. If this is important you could try to read 5 characters, 2 for month, 1 dummy, 2 for day.

If you used ignore, it would be cin.ignore(), not cin.ignore(/). You just have to assume that the character that is being ignored is '/'.

Can I limit the space that each takes up like?

cin>>Month[2]>>Dummy[1]>>Day[2];

Or would I limit it within int

int Month[2];
char Dummy[1];
int Day[2];

Code:

char Month[2];
char Day[2];
char Dummy;

std::cin >> Month[0] >> Month[1] >> Dummy >> Day[0] >> Day[1];

This isn't doing it... I was trying to get it to display... make sure that it's reading what's being inputed and I get wierd character in between the numbers

Code:

cin >> Month[0] >> Month[1] >> Dummy >> Day[0] >> Day[1];
cout<<Month<<" "<<Day;

I was trying to display the numbers back to myself to verify they went in correctly... i'll try it with some math and see if they work.


edit: didn't capitalize

Month and day is an array of characters, NOT an integer. Trying to print it like you do is dangerous since the compiler thinks it's a string, but it has no terminating NULL character.

What exactly are you trying to do, if you need the month/day as a whole number I still recomend my initial suggestion.

Here's the exact program from the assignment:

Write a complete program that tells zodiac signs. Ask the user for their birth month and day. Let the user that thye MUST enter the information as follows:
numeric month/numeric date. For example: 4/13

Given that information, tell the user which zodiac sign they are. Here's a list:

* Aries - March 21 - April 20
* Taurus - April 21 - May 21
* Gemini - May 22 - June 21
* Cancer - June 22 - July 22
* Leo - July 23 -August 21
* Virgo - August 22 - September 23
* Libra - September 24 - October 23
* Scorpio - October 24 - November 22
* Sagittarius - November 23 - December 22
* Capricorn - December 23 - January 20
* Aquarius - January 21 - February 19
* Pisces - February 20- March 20

I think I need to use logic statements so I can define month/day and where they fall... like if month = x and day is < y then you are a capricorn, etc.

Here's what I'm working with now... Lots of <b>if</b> statements to do it though...

Code:

//This program will help determine zodiac sign
#include <iostream>
using namespace std;

int main()
{
	int month,day;

	cout<<"Please enter your Birth month (2 digit form)\n";
	cout<<"Example:  February = 02\n\n";
	cin>>month;
	cout<<"\n\nPlease enter the Day of your birth (2 digit form)\n";
	cin>>day;
	if (month==01 && day<=20)
		cout<<"Capricorn\n\n";
	if (month==01 && day>20)
		cout<<"Aquarius\n\n";
	if (month==02 && day <=19)
		cout<<"Aquarius\n\n";
	
return 0;
}

I'd use some kind of structure for easy lookup of the sign. Are you allowed to use structs/STL? Perhaps your latest lecture may hint what to use to solve it?

No lecture hints unfortunately. This is an online class. I have it almost built until I come into the 8th, 9th month. Says:

illegal digit '8' for base '8'

Error for 8 and 9... I don't know how to fix that.

The leading 0 (08) means you're typing in base 8 rather than base 10. Remove the 0 and it'll be fine.

Footnote: Prefix with 0x to use base 16.

nevermind... i deleted the zero's from 08 to 8 and it works.

Thanks

ha... you typed that when I did... lol

Just so I know, though... why does it only do that with 8 and 9?

The leading 0 means that the number is base 8 (octal). Only digits 0-7 are valid in octal, like digits 0-9 are valid in decimal and 0 and 1 are valid in binary.
