Use

Code: Select all

``while(scanf("%d%d%d%d%d%d%d%d%d",&d8,&d7,&d6,&d5,&d4,&d3,&d2,&d1,&c)==9)``
remove

Code: Select all

``system("PAUSE");``
And check the cases.
Input:

Code: Select all

``````21 92 80 74 28 0 -71 -96 -21

I cant get the program to even process 9 ones. It just closes. Does anyone know why? code is the same as above with the system("PAUSE") removed and ==9 added just before the last bracket of the while(where jan said). Cheers. Scott

### Re: 392...Polynomial Showdown

Hi midra...
I hope you would have solved it by now... Anyway i ran your code on some i/o.

In the first term of output (whichever it is), there should be no spaces between '+/-' sign and the term.

These are the INPUT:

Code: Select all

Hope it helps.

P.S: Forgive me if i had said something wrong
I am not totally useless, because I can still be used as a bad example

### Re: 392 - Polynomial Showdown PE -- plz help

for this input

Code: Select all

``````0 0 0 0 0 0 1 0 0
``````
ur program gives

Code: Select all

``````x^2_
``````
here I replace space character with '_';
so ur program gives an extra space .
hople it helps.
It is tough to become a good programmer.
It is more tough to become a good person.
I am trying both...............................

### Re: 392 - Polynomial Showdown (Presentation Error)

Code: Select all

``````if(p[8] != 0)
{
if(p[8] == 1) cout << "x^8" ;
else if(p[8] == -1) cout << "-x^8" ;
else if(p[8] > 0) cout << p[8] << "x^8" ;
else cout << " -" << fabs(p[8]) << "x^8" ;
c++;
}``````
last else - cout << " -"
shouldn't it be cout << "-"
