I need help on coding this program

[wanderevil]

Create a program that will ask the user to input his/her birth month and birth date. The program should display the ZODIAC SIGN and its description based on his/her input month and date.

Use the table of Zodiac Sign below:
AQUARIUS - January 20 – February 18
PISCES - February 19 – March 20
ARIES - March 21 – April 19
TAURUS - April 20 – May 20
GEMINI May 21 – June 20
CANCER June 21 – July 22
LEO July 23 – August 22
VIRGO August 23 – September 22
LIBRA September 23 – October 22
SCORPIO October 23 – November 21
SAGUITTARIUS November 22 – December 21
CAPRICORN December 22 – January 19

Sample Output:
Enter your Birth month: 12
Enter your Birth date: 03
** Your Zodiac Sign is SAGUITTARIUS..

(And the description of SAGUITTARIUS)

and also the program should continue asking the user if he/she wants to test another input.

what codes should i use? i don't even know where to start..thanks guys!!

[HiteshVaghani1]

Rough idea
take input date and month.

cin>>date;
cin>>month;

if((month == 1 && date >= 20) || (month ==2 && date <= 18))
cout <<" Your Zodic Sign is SAGUITTARIUS..";
else if(condition for PISCES)
.
.
.
and so on;

[kbw]

That seems straightforward enough. What's the problem?

[wanderevil]

i'll try that..thanks but how about when the program should continue asking the user if he/she wants to test another input?

[wanderevil]

the problem is i can't start coz i don't know what to use..i'm thinking of else if and also do while..

[viliml]

Well then do it!

[TheIdeasMan]

Have we got another troll? If so my second one today.

If not, then demonstrate you can do something, (anything) for your self.

[dem7w2]

Since the program may possibly have to run again aka LOOP then you'll need a looping mechanism. I'm sure you can figure out if you play around with it. That's the quickest way to learn.

[wanderevil]

guys, i'm having a problem

i already made the code but there is this problem

the output is:
enter birth month: 300
enter birth date: 31
invalid input

but when i tried this:
enter birth month: 12
enter birth date: 300
your zodiac sign is CAPRICORN

how do i fix this?

#include <iostream>
using namespace std;
int main()

{
    int month,date;
    cout<<" Enter your birth month:";
    cin>>month;
    cout<<" Enter your birth date:";
    cin>>date; 
    
    if (( month == 1 && date >= 20) || ( month == 2 && date <=18))
    {
         cout<<" Your zodiac sign is AQUARIUS\n";
         
    }
    else if (( month == 2 && date >= 19) || ( month == 3 && date <= 20))
    {
         cout<<" Your zodiac sign is PISCES\n";
    }
    else if (( month == 3 && date >= 21) || ( month == 4 && date <= 19))
    {
         cout<<" Your zodiac sign is ARIES\n";
    }
    else if (( month == 4 && date >= 20) || ( month == 5 && date <= 20))
    {
         cout<<" Your zodiac sign is TAURUS\n";
    }
    else if (( month == 5 && date >= 21 ) || ( month == 6 && date <= 20 ))
    {
         cout<<" Your zodiac sign is GEMINI\n";
    }
    else if (( month == 6 && date >= 21 ) || ( month == 7 && date <= 22 ))
    {
         cout<<" Your zodiac sign is CANCER\n";
    }
    else if (( month == 7 && date <= 23 ) || ( month == 8 && date <= 22))
    {
         cout<<" Your zodiac sign is LEO\n";
    }
    else if (( month == 8 && date >= 23 ) || ( month == 9 && date <= 22 ))
    {
         cout<<" Your zodiac sign is VIRGO\n";
    }
    else if (( month == 9 && date >= 23 ) || ( month == 10 && date <= 22))
    {
         cout<<" Your zodiac sign is LIBRA\n";
    }
    else if (( month == 10 && date >= 23 ) || ( month == 11 && date <= 21))
    {
         cout<<" Your zodiac sign is SCORPIO\n";
    }
    else if (( month == 11 && date >= 22 ) || ( month == 12 && date <= 21))
    {
         cout<<" Your zodiac sign is SAGUITTARIUS\n";
    }
    else if (( month == 12 && date >= 22 ) || ( month == 1 && date <= 19 ))
    {
         cout<<" Your zodiac sign is CAPRICORN\n";
    }
    else
    {
        cout<<" INVALID INPUT";
    }
         system("pause");
}

[dem7w2]

You need to add another condition

  else if (( month == 12 && date >= 22 && day <= 31) || ( month == 1 && date <= 19 ))

You'll have to do that on every month. Some will be <= 30, others <= 31 depending on the month. And Feb is <= 28.

Also none of them can be negative. Instead of declaring day and month as type int, use unsigned int.

i.e.
unsigned int month, day;

[wanderevil]

Oh, thanks and btw, how can i put a yes/no question?

example output:

Enter birth month: 12
Enter birth date: 12

Your zodiac sign is SAGUITTARIUS..

Do you want to continue? [Y/N]
y

then it will go back to enterering birth month and date..

[dem7w2]

Well what type is 'y' and 'n' ? That's the type you want to use. As for looping back up your program, use a looping mechanism.

[wanderevil]

i don't know how to loop back to the enter birth month/date..and should i declare y and n as an integer? sorry kinda newb

[dem7w2]

Check the do-while tutorial in my link I just posted.

As for the y/n question – well you'll have a variable called something like answer and you will:

cin >> answer;

answer should either be 'y' or 'n' (or 'Y' or 'N').

You'll declare answer at the top. As for its type, I'll give you a multiple choice.
A) int
B) float
C) string
D) char

[wanderevil]

There is a problem with your code..when i input 'n' which means no..it still continues to entering the date/month..

EDIT: typo

[Hippogriff]

Change
while (!((ans=='n')&&(ans=='N'))){
to
while (!((ans=='n') || (ans=='N'))){

The first one means it has to be n 'and' N. The second one means it has to be n 'or' N.

I would also either give ans some sort of starting value or change it to a do-while loop so that it works correctly the first time.

[HiteshVaghani1]

while (!((ans=='n')&&(ans=='N'))) will never false..
use
while (!((ans=='n') || (ans=='N')))

[wanderevil]

thanks guys!!!

[wanderevil]

I would like to add..

what if the person inputs neither y/n..so i need to display INVALID INPUT. Please try again.
