How do I check if input is just an empty line??
Code:input = fopen("test.dat", "r"); while (!feof(input)){ if(fscanf(input, .................... }

The same way you check to see if it's an empty line in notepad. Look at it and see what's there.

You should be able to figure out what it does, it just makes sure that there are two lines because if there is a character preceding the newline character than that line is not empty.Code:#include <stdio.h> int main( void ) { char buffer[20] = { 0 }; int a, charsread = 0; input = fopen("test.dat", "r"); while (!feof(input)) { charsread = fscanf(input, "%20s", buffer ); for( a = 0; a < charsread; a++ ) //a++ is preferred because it looks better ;) { if( buffer[a] == '\n' && buffer[a + 1] == '\n' ) { printf("Empty Line found\n"); } } } fclose(input); return 0; }

Hi!Originally Posted by -EquinoX-
Try this:
Code:char c; input = fopen("test.dat", "r"); do { c = fgetc(input); if(c != ' ' && c!=EOF) { printf("File not only empty line \n"); exit(0); } }while (c!=EOF); printf("File only empty line \n");
It depends on your definition of blank. Like I said, look at it and decide if it's blank.
