Reading from a txt file into a two dimension array in C

kponenation · 11-26-2005, 05:35 PM

I'm trying to read from a txt file into a two dimension array. The text file contains following data.

Code:

0 0 0 1 0 0 1 0 1 0 0 1
1 0 1 0 1 0 1 0 1 0 0 0
0 0 0 0 0 0 0 1 0 0 0 0
1 1 0 1 0 1 0 1 1 1 1 1

I want to create a two dimensional array (in this case 4X12 array) by reading the txt file.
Can anyone give me a hint on how to do this?

Thanks

my code looks something

Code:

if (fp == NULL) exit(EXIT_FAILURE);
     for (i=0; i<r; i++)
         for (j=0; j<c; j++){
             fread(a[i][j], 1, c, fp);
                                 }
                       
   }

of course it doesn't compile.

something like this

Code:

man fopen
man fgets
man fscanf
man fclose

These should help you. It's not al all difficult.

I used fscanf to solve the problem...
Problem solved!!
