RE: Re: RE: Re: C++ Help

You messed up your logic for the x and y axis stuff...

Should be:

input x, input y
if x==0 and y==0
then output "origin"
else if x==0 and y!=0
then output "y-axis"
else if y==0 and x!=0
then output "x-axis"
else if x > 0 and y > 0
then output "first quadrant"
else if x < 0 and y > 0
then output "second quadrant"
else if x<0 and y<0
then output "third quadrant"
else if x>0 and y<0 then output "fourth quadrant"

That is far from tedious as far as code goes...

Edit for bad include syntax <_<

RE: Re: RE: Re: C++ Help

you forgot the most important part.

I'll let you try to figure out where it is...

[QreepyBORIS]

RE: Re: RE: Re: C++ Help

Gosh, I can't figure it out, Talis (or can I?).

If you read that sentence above and you have a brain, you'd know I know what the errors would be.

Oh, snap, I read the code again and there's actually another, much more glaring error in Nipunn's code. How could you, man? I always add that in first.

Also, you should declare a namespace. It's a good practice.


Also, you should make x and y doubles, then ask for their input on the same line (as in, cin >> x >> y. You just need a space between the two numbers when you input them.

Also, you should use newlines and grammar to spice it up.

 if x==0 && y==0
    cout << "origin";

    cout << "second quadrant";
 if x<0 && y<0
    cout << "third quadrant";
 if x>0 && y<0 
    cout << "fourth quadrant" ;
&#125;

ok std::namespace
and cin both on the same line
I stole all the words from talisman/sccr
plus I forget how to newline >_> is it like std::endl or can I just cout a "\n"

[QreepyBORIS]

RE: Re: RE: Re: RE: Re: C++ Help

You can newline two ways.

Here is and example of each:

cout << "Cock goes where?\n";
cout << "Cock goes over there. -->" << endl;

Okay.

By the way, you should probably stick the namespace right under your includes. It's just easier than sticking it into every single function in the program.

And since you missed it: You forgot to return 0! You also forgot to put parentheses around your conditionals. Shame, man. :P

Re: RE: Re: RE: Re: C++ Help

#include <iostream>
using namespace std;

void main&#40;&#41;
&#123;
 double x,y;

 cout << "enter an x and a y";
 cin >> x;
 cin >> y;
 if x==0 && y==0
    cout << "origin";
 if x==0 && y!=0
    cout << "y-axis";
 if y==0 && x!=0
    cout << "x-axis";
 if x > 0 && y > 0
    cout << "first quadrant";
 if x < 0 && y > 0
    cout << "second quadrant";
 if x<0 && y<0
    cout << "third quadrant";
 if x>0 && y<0 
    cout << "fourth quadrant" ;
&#125;

Assuming you don't need parentheses around the conditional statements (which I always just put), that code'll work.

RE: Re: RE: Re: RE: Re: C++ Help

yeah... I was going for the return 0; part... otherwise any half decent compiler will rape you if you try to make it compile that code.

ok stupid conditionals parentheses >_<
silly me
anyway, even though its too late I feel the need to fix it

you can do a main without a return I believe.

[talisman]

RE: Re: RE: Re: RE: Re: C++ Help

main () isn't even a function... I thought you had to say int main(); which means it has to return an integer. Could be wrong about that.

[QreepyBORIS]

RE: Re: RE: Re: RE: Re: C++ Help

You can do void main with some compliers only. But you did not specify a data type for main...what were you thinking? :P

[GuidoHunter]

RE: Re: RE: Re: RE: Re: C++ Help

I know from experience that the compiler Jurs is using will accept void main() and that you need a function type in front of it.

Also, chicken, I'm still not sure of thes, but I would have written the conditional lines like:

if ((y==0) && (x==0)

I do that just to be safe, but again, I'm not sure exactly which parentheses are actually necessary (although I'm rather certain the outside ones are.

Thank you guys <333 I finished.

I got an 83 though because my teacher hates me (from last year) and I finished a day later.

Re: RE: Re: RE: Re: RE: Re: C++ Help

if ((y==0) && (x==0)

I do that just to be safe, but again, I'm not sure exactly which parentheses are actually necessary (although I'm rather certain the outside ones are.

Yea, you can use as many as you want, but the easiest way:

if (y == 0 && x==0)
{
}

The inside ones are not necessary.
