bitset

Member Function	Description
all	It returns true when all bits are 1. It returns false, if one or more bits are 0.
any	It returns true when at least one bit is 1. It returns false, if all the bits are 0.
count	It returns the total number of bits set to 1.
flip	It toggles the value of all the bits, or it toggles a single bit at the specified position.
none	It returns true when all bits are 0. It returns false, if one or more bits are 1.
reset	It sets the value of all the bits to 0 or at the specified position.
set	It sets the value of all the bits to 1 or at the specified position.
size	It returns the number of bits.
test	It tests whether the bit at a specified position is o 1.
to_ullong	It returns the sum of the bit values as an unsigned long long.
to_ulong	It returns an unsigned long that would generate the sequence of bits contained if used to initialize the bitset.
to_string	It returns a string representing the bits.

// the value of text is number eleven in binary: L"1011"

Program3.cpp

#include <bitset>

Sys::BoolArray

Wintempla provides the Sys::BoolArray class to efficently store an array of bools, the size of the array can be set at run time and can handle bigger arrays than bitset .

Wintempa proporciona la clase Sys::BoolArray para almacenar en forma eficiente un arreglo de bools, el tamaño del arreglo se puede fijar en el momento de ejecución y puede manejar arreglos más grandes que bitset.

Program1.cpp

Sys::BoolArray data(10);
for (size_t i = 0; i < data.GetBitCount(); i++)
{
data.SetBit(i, i%2 == 0);
}
data.Show(hWnd, L"Value");

Program2.cpp

Sys::BoolArray data(18);
for (size_t i = 0; i < data.GetBitCount(); i++)
{
data.SetBit(i, i%3 == 0);
}
wstring text;
data.GetString(text);
::MessageBox(NULL, text.c_str(), L"BoolArray", MB_OK);

Program3.cpp

Sys::BoolArray data(L"000011110001");
data.Show(hWnd, L"1");
const int count = data.GetActiveBitCount();
wchar_t text[32];
_snwprintf_s(text, 32, _TRUNCATE, L"Number of Ones = %d", count);
::MessageBox(NULL, text, L"BoolArray", MB_OK);
data.SetAllToOne();
data.Show(hWnd, L"2");
data.SetAllToZero();
data.Show(hWnd, L"3");
data.FlipBit(3);
data.Show(hWnd, L"4");

Program4.cpp

Sys::BoolArray data(24);
data.SetInt8(0, 120);
data.SetInt8(1, 92);
data.SetInt8(2, -40);
wchar_t text[64];
_snwprintf_s(text, 64, _TRUNCATE, L"%d, %d, %d", data.GetInt8(0), data.GetInt8(1), data.GetInt8(2));
::MessageBox(NULL, text, L"BoolArray", MB_OK);

Program5.cpp

Sys::BoolArray a(L"1011101110011");
Sys::BoolArray b(16);
b.CopyBits(a, 2, 8);
b.Show(hWnd, L"b");
