COUTing a BYTE with Dev C++
Author
Hi,
For the given example below:
#include <iostream>
using namespace std;
int main()
{
BYTE number;
number = 65;
cout << number << endl;
}
MSVC will output 65 as expected (my expectations anyway) while Dev C++ will output 'A'
How can I get the first behavior using Dev C++? I don't want to use an int for number because in my real program I perfom some bitwise computations which will be wrong using a 32 bit int but works with an 8 bit BYTE.
Thanks,
Darryl
typedef unsigned char BYTE;
that should do it.
you might want to make a header file of your own of the typedefs you want.

Still outputs 'A' and not 65. BTW I looked through the headers and found that's the way it is already defined as an unsigned char. I imagine the problem is with iostream cout treating it as a char.

Well, DUH! An unsigned char (BYTE is just a typedef, it's not something that exists on its own) is a character. You know, a letter. Cast to unsigned int if you want a numerical value.
cout << static_cast<unsigned int>(number) << endl;
i should learn how to read.... [rolleyes]
if BYTE is an unsigned char then it makes sense that COUTting 65 would produce 'A'. 65 is the ASCII value for 'A'. try to cast it with (int).
so... cout << (int) number << endl;

I hear what you guys are saying, HOWEVER, using MSVC cout << BYTE outputs the number and not the character and I was hoping to somehow duplicate that behavior without cast. Basically how is MS defining BYTE or cout such that cout << BYTE outputs the value and not the character.
Guess I will just have to do the cast.

If so, MSVC's behaviour is incorrect. If you are using VC6, it is not surprising.
