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
44 -56 16 3 -57 -74 0 -10 50

Output:

Code: Select all

21x^8 + 92x^7 + 80x^6 + 74x^5 + 28x^4 - 71x^2 - 96x - 21
44x^8 - 56x^7 + 16x^6 + 3x^5 - 57x^4 - 74x^3 - 10x + 50

[scott1991]

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

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

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

These are the INPUT:

warning::::dont open a new thread while there r lot of threads.

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 .
think about that.
hople it helps.

last else - cout << " -"
shouldn't it be cout << "-"
