writting a C program
Nov 14, 2008 at 3:40am
this is one of my practice quizzes for my upcoming test, i am having way too much trouble writing the code for it out, help on writing this code out will be appreciated
Write a C program that normalizes the vector vec[5], whose components
are in the file vec_in.dat (which you need to copy). The components
of the normalized vector are defined as the original components devided
by the norm of the vecor, which is: norm=sqrt(v[0]^2+v[1]^2+....).
Write the original and the normalized components on the screen and in
the output file vec_out.dat. Close the files.
Your solution should look like this (on the screen and in the output file):
Original Vector = [ 1.200000 -2.300000 0.530000 2.010000 -1.500000 ]
Normalized Vector = [ 0.329033 ............................. -0.411291 ]

I certainly won't do your homework, but try to explicit separate steps, such as
1. reading the vector
2. computing its norm
3. normalizing the vector
And repeat this divide & conquer approach until each step is small enough to make it a C statement.
BTW, you are on a C++ forum, not a C one!
At last, take time to go to a library (with books on paper) and to read some books.
You need to learn how to do things by your own, not to have other people doing your homework
