Hi Everyone,
I am trying to read two text files swY40p10t3ctw45.col.txt and solution.txt
and compare them, the first text file has a bunch of values listed like:
y[1,1,1,1]
y[1,1,1,2]
y[1,1,1,3]
y[1,1,1,4]
y[1,1,1,5]
y[1,1,1,6]
y[1,1,1,7]
y[1,1,1,8]
and so on..
and I am trying to compare it with a text file that looks like:
C0001 1.0000000
C0215 1.0000000
C0817 1.0000000
C0078 1.0000000
where the C0001 is the first variable down from the top of the list and C0215 is the 215 th variable down from the list. So I want to find from the first list the 215th and output y[#,#,#,#} and the solution value 1.00000 or whatever is right of the C0215.
The problem I am having is that I can build my current C code below, but I when I debug it I get "UNC paths are not supported. Defaulting to Windows directory, Cannot open file"
below is my code:
/*
** FILE SOURCE6.C
**
** ASSOCIATED FILES TO BE READ:
** File swY.col
** File solution.txt
************************************************** **********************
** The file is opened for reading. Each line is successively fetched
** using fgets command. The string is then divided up and put into a matrix.
** Matrix will be of 4 dimensional
************************************************** **********************
** Note that fgets returns NULL when there are no more lines in the file.
************************************************** **********************
** In this file swY.col consists of various decesion variables.
************************************************** **********************
** Typical data in swY.col might be: y[1,1,1,1]
************************************************** **********************
** y[1,1,1,1] = y[d,t,k,i]=y[day,test,type,started at]
************************************************** **********************
** SO WE READ THE LINE FROM THE TEXT FILE, THEN WE CONVERT THE INTERGER
** VALUES TO VALUES IN THE MATRIX SO IF decesion variable is y[1,2,4,5]
** THEN THAT LOCATION IS [1,2,4,5] in the matrix
**
** In this file solution consists of various solution values for a column.
************************************************** **********************
** Typical data in solution.txt might be: C0001 1.00000000000
************************************************** **********************
** It would be desirious to read in the say C001 and know it value in a matrix
************************************************** **********************
** LATER THE ASSOCIATED DECESION VARIABLE WILL BE LINKED TO THE SOLUTION VALUE
** AND THEN OUTPUT WILL BE ADJUSTED AND PUT TO A WORD FILE OR ANOTHER TXT FILE.
