Use of getc()/putc() for reading/writing chars, floats, etc. from binary files?

Can getc()/putc()/fgetc()/fputc() be used to read/write chars and floats rather than ints only from binary files? If so, how?

Yes. you can read more about it here http://www.cplusplus.com/reference/clibrary/cstdio/getc.html

Yes you can use it, but I won't suggest it. Its a whole lot easier to use fread() and fwrite() to read/write to/from binary files.

// fgetc example
float f = 0;
unsigned char buf[sizeof(float)];
FILE* fp = fopen("myfile.dat", "rb");
// read a float
for(i = 0; i < sizeof(float); i++)
   buf[i] = fgetc(fp);
// move the contents of buf into the float variable
f = *(float *)buf;

Here is the same thing using fread

float f;
FILE* fp = fopen("myfile.dat", "rb");
// read the float
fread((char *)&f, sizeof(float),1,fp);

fread() is a lot less typing, lot less error prone, and more straight-forward.

Thank you very much, I didn't realize it would be that complicated to read with fgetc(). You're right, fread() is much better :)
