weird error..., I have no idea about this one...

Code:

---

FILE *f = fopen(filename, "r");
while(fgetc(f)<=0x20);
while(fgetc(f)!=0x0A);
int rows = 0;
int collumns = 0;
int companies = 0;
char current = 0x00;
char old = 0x00;
string currentcomp = "";
string lastcomp = "";
bool checkcomp = true;
while(current!=EOF) {
 current = fgetc(f);
 if(checkcomp) {
  if((current==0x09) || (current==0x0A)) {
  checkcomp=false;
  if(currentcomp!=lastcomp) {
    collumns++;
    lastcomp=currentcomp;
  }
  currentcomp="";
  rows++;
  }
  else {
  currentcomp.append((char*)&current);
  }
 }
 if(current==0x0A) {
  checkcomp=true;
 }
}

That is my code... The weird thing is, I want to do a ++ on companies instead of collumns in my code, but if I use the int companies I get wrong result, renaming the var doesn't work, the only thing that works that I've figured out is to use the collumns var... I don't get this, please help...

current should be and int.

Why? fgetc returns a char what I know of? And I just discovered that my code works if I add another integer (a dummy integer) below that int companies... I don't understand this...
