i guess because c# is strongly typed
Or...
if (true) ++count;
....which is arguably an order of magnitude more readable anyway.
Afterall, I'm still not sure if you wrote the number 1 or the letter l.

Gee, you must be an ex-C hack like me!
C was one of the few languages that got ints and bools confused. You
couldn't do that in Pascal, either!
C# is strongly typed: booleans and integers are different things. I
prefer it, but that's just me. :)
Let me give you more background.
I wanted to count bits on type byte, and I found a c routine: http://www.caam.rice.edu/~dougm/twiddle/BitCount.html
int count = 0;
int tmpbits = bits;
while (tmpbits) {
if (tmpbits & 1) ++count;
tmpbits >>= 1;
}
return count;
but to turn it into a c# method requires:
int cbits(byte b)
{
int count = 0;
int tmpbits = b;
while (tmpbits>0)
{
if ((tmpbits & 1)==1) ++count;
tmpbits >>= 1;
}
return count;
}

If requires a condition that evaluates to either true or false. 1 does not
evaluate true or false. You can either go with your second line, or:
if(true) ++count;
For us former C/C++ developers, we can also do:
if(Convert.ToBo olean(1)) ++count;
Convert.ToBoole an(short/int/long/double/decimal) overloads return true if
the value is non-zero, otherwise false.

I see where you're coming from now.
So the ole bit count eh? Here is what I used recently for a chess
engine in C#.
public int BitCount(UInt64 bitboard)
{
int count;
for (count = 0; bitboard != 0; bitboard &= bitboard - 1;) count++;
return count;
}
This is one function I was hoping would be implemented by the framework
because the JIT compiler could output the faster x86 instructions for
bit counting if the application was running on a CPU that supported
those instructions.

no, because that's infinitely worse.
for example, if I intend to do if(i == x) but wrote if( i = x ), in your
scenario, it will still run, but will become a hard to track bug.

Worse? Not at all, if( i = x ) won't even compile as the expression is of
type int and if expects a bool.

No, that's exactly what Daniel was saying. In the kind of situation the
OP was talking about (where if(1) compiles), for instance in C, you get
the type of problem Daniel mentioned.

is C++ smart enough to automatically use "bits" for bool or will
a bool have the size of a charcter (byte).
2) The index of a vector is it an integer (4 byte) or a "long long"

Is the bool type actually an Int32 with 0 as false and non zero as true? The

What do you make of this? I cannot tell for sure but it almost seems as
the the transition thunk to get back from the native bool method to the managed
caller is looking at eax and, if any bit is set, normalizing it to 0x00000001.
If it wants to normalize the value then it should only operate on the al
register since that's all that the native bool method uses to hold the return
value.
Is this a known VC 7.1 bug? Is there a hotfix...

hi, there
I am using a big, sparse binary array (size of 256^3). The size may be
changed in run time. I first thought about using the bitset but found
its size is unchangeable. If I use the vector<bool>, does each element
takes 4 bytes instead of 1 bit? I am using gcc3.4.4. There is a
bit_vector which is kind of old so I wont use that. Any other choices?
Thanks ahead.

I have code which says
#define MYBOOL int
This code is very old. people who have written is not avaible. I was
thinking what could be reason.
1) bool datatype was not available that time (10 years back: correct me
if i am wrong)
2) int was word aligned (16bit and 32bit). Writter of above code doesnt
want to give choice to compiler.

Hi
My C# app is being called from a callback from an unmanaged DLL. One of
the parameters of the callback is of type BOOL. I am using PInvoke to
marshal this to a (managed) bool. The problem is that no matter if we
pass TRUE or FALSE, the bool is always marshalled as true.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
