Matrix in a file. Help!

I write a matrix in a text file as it shows the example:

2 5 2 5 6
2 3 4 6 3
2 5 6 8 6

I want to find out the number of lines and columns. I've started writing the code but I can't determine the number of lines.

Code:

#include <stdio.h>

int main()

{
FILE *f;
f = fopen ("mat1.txt", "r");
int spaces=0, endl=0;
char c, d;
do {
      fscanf(f, "%c", &c);
      if ( c == ' ' )
          spaces++;
     }
while ( c != '\n' );
fseek ( f, 0, SEEK_SET );
do {
      fscanf(f, "%c", &d);
      if ( d == '\n' )
          endl++;
     }
while (!EOF);
printf("The matrix has %d columns and %d lines.", spaces+1, endl+1);
fclose(f);
return 0;
}

What did I do wrong ?

Well what's the output?

Code:

while (!EOF);

EOF is a constant. !EOF is the same as

Code:

while (0);

The matrix has 5 columns and 1 lines.
This output is for the example I gave.

Both your file reading loops need to be of this form

Code:

while ( fscanf(f, "%c", &c) != EOF ) {
  // do something with c
}

In the first loop, you could do this to get out of the loop when you see the first newline
if ( c == '\n' ) break;

user fgets() function to find out the number of lines.

Code:

    while(fgets(str,80,fp) != NULL)
        line++;

this gives you the number of lines which u have read. By keeping tack of line variable

to find out the num of col it depends on the way each file is stored

example: if your line is stored with out the space like

Code:

12345

just count the num of char in a line. or if you have like this

Code:

1 2 3 4 5

use this tokenize the string
