well, while this sounds liks a cool problem, i don't have the time to write a proggy that does this stuff right now. Let me give you some pointers (har har, get the pun!!):
start out simple. Write the functions, which are going to handle your I/O first. See that you get the information correctly from the user.
Next see if you have write a function, let's call it
code:
int displayLine(int iTry, int iRoot, int iError)
which takes three ints and returns 0 if it executed sucessful. this function, uses the three integers provided to create one line of the array, which u are supposed to print.
If you are not getting many point for how teh array looks, u might just want to do a cout on this stuff and dump it to the screen before worrying about formatting.
one good thing is that there is a cout command, which let's u set the number of decimal places, which are displayed.
After you got your I/O sorted, it is time to crank out some Math book and figure out how the newton method is done. I don't know this off-hand (I remeber newton-raphson method for finding the zero's of functions).
From the problem statement, i assume that it will be an interative algorithm. You can then write a function
code:
int Newton(int iSeed, int& iRoot, int& iError)
which will do one iteration of your algorithm and put the new root into iRoot, the new error into iError and returns 0 if it is successful.
Now you should have everything u need to write a little main loop, which uses these function stubs to ask for input, compute the rows, till the error == 0 and prints out one row at a time.
I hope that this helps a bit
