Noob Q: How to read a value of a byte in binary?

Hi Everyone, I'm a noob a programming and I've been desperately trying to read a single byte of a file in binary. But whenever I look online all I can find is.

Code:

---

#include <iostream>
#include <fstream>
using namespace std;

ifstream::pos_type size;
char * memblock;

int main () {
  ifstream file ("example.bin", ios::in|ios::binary|ios::ate);
  if (file.is_open())
  {
    size = file.tellg();
    memblock = new char [size];
    file.seekg (0, ios::beg);
    file.read (memblock, size);
    file.close();

    cout << "the complete file content is in memory";

    delete[] memblock;
  }
  else cout << "Unable to open file";
  return 0;
}

I get that and how it can be used with write() to copy a file, but what I need is to read the value of a, specific byte and maybe copy it to an array or int. How do I do that?

Please help.

Code:

---

char c;
file.read (&c, sizeof(char));

Of course you may want to seek to the proper byte position that you wish to read first.

Thanks Valaris! I think I can use this.
