This homework will count towards your grade. It is very important that 
you follow the instructions very carefully. 

Homework: page 337, problem 9; page 339, problem 22. 

Note: there is an error for problem 22 in page 339, the i+j should be 
the exponential of (-1). It is NOT (-1)*i+j !!!
And there is an error for problem 9 in page 337, the function prototype should be
double row_ave(double x[][NCOLS], int row); 

For the problem 9, use the following text file as the input data file:

the hw8 directory in your acms20210hw directory. These exercises should 
be named in the following way before submission:

The data file power1.dat must also be copied from your hw8 directory to the homework 8

Important: REPLACE the "yourNetID" in the above command by your NetID !!!

your homework at any time before the deadline: the old files will be 
replaced by the new files.
