c - reading a file using getc and skipping a line if it starts with semicolon -

while((c = getc(file)) != -1) {     if (c == ';')     {         //here want skip line starts ;        //i don't want read more characters on line     }     else     {                         {                 //here stuff                }while (c != -1 && c != '\n');//until end of file     } } 

can skip line using getc if first character of line semicolon?

your code contains couple of references -1. suspect you're assuming eof -1. that's common value, required negative value — negative value fit in int. not bad habits @ start of career. write eof checking eof (and don't write eof checking -1).

int c;  while ((c = getc(file)) != eof) {     if (c == ';')     {         // gobble rest of line, or until eof         while ((c = getc(file)) != eof && c != '\n')             ;     }     else     {                 {             //here stuff             …         } while ((c = getc(file)) != eof && c != '\n');     } } 

note getc() returns int c declared int.
