Converting strokes from C++ to C!

[kiksu]

Hi,

I have problem,that I have to change programming language from C++ to C, but i don't get how to make these strokes work in C language!
There is the following strokes, what I need to change:

std::ifstream in("file.txt", std::ios::binary);
if (in.is_open()) {
int cnt=0;

in.read(reinterpret_cast<char *>(&iSk), sizeof(int));
mas = (student*)calloc(iSk, sizeof(student));
while (cnt <= iSk) {
in.read(reinterpret_cast<char *>(&mas[cnt]), sizeof(student));
cnt++;
}
}
in.close();

I hope someone can help me,if there is some questions please write to me!

Loop up the C standard library functions

fopen
fread
fwrite
fclose

I tried and i get this one -

pf=fopen ("file.txt","r");
   if (pf == NULL) {
  perror("Mistake!");
  return;
  }
  else {
  int cnt=0;
  cnt=getc(pf);
  if(ch==EOF);
  printf("File is empty!\n");
  while (cnt !=EOF){
  printf ("%c\n",cnt);
  cnt=getc(pf);}
  }
 fclose (pf); 

Is it right?

You have your braces { } laid out strangely.
Line 9 looks wrong, looks like you are checking the wrong variable (ch not cnt) and you have a ; at the end of it.
