c - found extra whitespace while using fscanf -

i have file:

hello:12312 bye:333 hey:22 

so read using fscanf

 file *file = fopen( argv[1], "r" );          if ( file == 0 )         {             printf( "could not open file\n" );         }         else         {              while(fscanf(file, "%[^:]:%d", word, &integer) != eof)             {                 printf("word: %s, integer: %d\n", word, integer);             }              fclose( file );         }  

and got:

word: hello, integer: 12312 word: bye, integer: 333 word: hey, integer: 22 

so apparently there whitespace except first word, why happening?

from fscanf():

all conversion specifiers other [, c, , n consume , discard leading whitespace characters before attempting parse input.

and \n remain input stream after "%d".

to correct add leading space format speicifer skip whitespace:

while(fscanf(file, " %[^:]:%d", word, &integer) == 2) { } 

changed != eof == 2 prevent accepting lines of format "hello:" or "hello".
