Determine number of columns in a file

I want to determine the number of columns in the file with :

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

it is a text file,I can determined the number of lines using the function gets () for the number of columns,but unable to determine column in file.

/

Code:

---

* Read the file to find the number of lines * /
        while (fgets (string, max_size, file)! = NULL) 
          / * Fgets () reads a string until the newline * /
          line + +; / * on the number of newline * /
   
        printf ( "row =% i", line);
     
        nl = line;
     
        / * Read the file to find the number of columns * /
        rewind (file);
        while ((c = getc (file))! = atoi ( "n"))
          if (c! = atoi ( "")) + + column; 
        nc = column;

If you know fgets () Function retrieves a character then Just put this function in a loop, your characters repeated one after the other until the '\ n' End of line and the number of columns also repeated in loop.

with strlen () it does not work, and I suppose that a space is counted as a character, so it forced me to subtract the number of space ...

Code:

---

/ * Read the file to find the number of lines * /
        while (fgets (string, max_size, file)! = NULL)   
          / * Fgets () reads a string until the newline * /
          nl + +; / * on the number of newline * /
        printf ( "row =% i \ n", nl);
     
        / * Read the file to find the number of columns * /
        rewind (file);
        while ((nc = getc (file))! = '\ n')
          if (nc! = '') nc + +; 
        printf ( "column =% i \ n", nc);

You can create a file called column.dat that contains the text
22 23 24
25 26
by entering the following commands

Code:

---

clear
    file = "temp.dat"
    rmfile(file);
    write(file, "22 23 24 ")
    write(file, " 25 26")
    close(file)

---

If you then enter

Code:

---

ncols("temp.dat", "int")

---

O-Matrix will respond
{ 24, 23 }
because column.dat has three integers in its first row and two in its second row. If you continue by entering ncols("column.dat", "char")
O-Matrix will respond
{ 26, 24 }
because column.dat has five characters in its first row and three in its second row (there is one space between each of the numbers).
