You may know about strtok in C.

Ex.

char str[] = "studentdetails.txt";
char delims[] = ".";
char *result = NULL;
result = strtok( str, delims );
while( result != NULL ) {
    printf( "%s\n", result );
    result = strtok( NULL, delims );
}

You can use a strtok() function.

char str[] ="This is a sample string, just testing.";
char *p;

printf ("Split \"%s\" in tokens:\n", str);

p = strtok (str," ");

while (p != NULL)
{
    printf ("%s\n", p);
    p = strtok (NULL, " ,");
}
return 0;

I have used a space... just use "." instead

better use `strtok_r()` for safety (and readability) reasons. – The Paramagnetic Croissant Jun 28 '14 at 06:55

The word is you rather then u. If it's worth writing an answer then it's worth using real words rather than text speak. – David Heffernan Jun 28 '14 at 07:39
The word is "than" and not "then" in your first sentence. If it's worth writing a comment, then its worth using proper grammar than not using one. sorry couldn't help myself. Cheers. :) – Jay Nirgudkar Jun 28 '14 at 07:44
