Hex char to string of text?

I'm getting inoput from a binary file, in hex.
And I want it to say the first nine characters... like "0x05 0x53,0x84 " ... and so on. So how do I turn a char in hex to a string in text?

Well, it's a bit ugly, but:

Code:

---

#include <iostream>
#include <iomanip>

int main() {
    char c = 0x05;
    std::cout << "0x" << std::setw(2) << std::setfill('0') << std::hex << (int)c << std::endl;
    return 0;
}

There may be an easier way. Of course, you could always use the C functions for this.

Code:

---

printf("0x%02x\n", c);

---

What about mutiple hex numbers?
Like:
char bob[3] = {0x82,0xF4,0xED};

Well, you just do it in a loop! Repeated executing

Code:

---

std::cout << "0x" << std::setw(2) << std::setfill('0') << std::hex << (int)bob[x] << ' ';

---

should do what you need.

What if I can't use cout.

Then you shouldn't have posted in the C++ forum. And the first reply had the C version too.

If you need to use C++, but want to generate a std::string to use later, you can use stringstreams. See the FAQ for details.
