Hello comerades
I am just developing a C program to create an input file, read some
part of data from the file and use them for computation. At this
time, i have been to create and read(and print to screen) values from
the input file created. The file looks like this:
1 1 1 45.98
1 1 2 34.09
1 2 1 44.09
1 2 2 65.98
2 1 1 34.99
2 1 2 74.07
2 2 1 87.09
2 2 2 66.90
All attempts to use the fourth column of data for further computation
have failed. This column is a three dimensional array of the first
three column. For example, I obtain very funny numbers as I try to
multiply the fourth column of data by say 2. Has any c programmer
faced this problem. I am very sure I am not doing something right
this is the way my code looks like
int c1,c2,c3,a,h,s;
FILE *infile;
float d[5][5][5],t[5][5][5];
float v1[5][5][5],v2[5][5][5],v3[5][5][5];
a=h=s=2;
if((infile = fopen("test.dat", "r")) == NULL)
{
fprintf(stderr,"Error opening file");
exit(1);
}
for(c1=0; c1<a; c1++)
{
for(c2=0; c2<h; c2++)
{
for(c3=0; c3<h; c3++)
fscanf(infile,"%d %d %d%f", &v1[c1][c2][c3],&v2[c1][c2][c3],
&v3[c1][c2][c3], &d[c1][c2][c3]);
printf("%d %d %d %f",
V1[c1][c2][c3],v2[c1][c2][c3],v3[c1][c2][c3];d[c1][c1][c3]);
t[c1][c2][c3]=2*d[c1][c2][c3];
/*this is where the error sets in; t[c1][c2][c3] just comes as
gabbage */
}
}
}
fclose(infile);
}
