class KeyboardState {
private:
bool pressed, held, released, oldState;
public:
bool IsPressed();
bool IsHeld();
bool IsReleased();
void KeyDown();
void KeyUp();
};

KeyboardState keyboard[256];

bool KeyboardState::IsPressed() {
bool val = pressed;
pressed = false;
return val;
}
bool KeyboardState::IsHeld() {
return held;
}
bool KeyboardState::IsReleased() {
bool val = released;
released = false;
return val;
}

void KeyboardState::KeyDown() {
pressed = released = false;
if (!oldState) {
pressed = !held;
held = true;
}
oldState = true;
}

void KeyboardState::KeyUp() {
pressed = released = false;
if (oldState) {
released = true;
held = false;
}
oldState = false;
}

// In windows management events:
case WM_KEYDOWN:
key = mapKeys[(const unsigned short)wParam];
keyboard[key].KeyDown();
return 0;

case WM_KEYUP:
key = mapKeys[(const unsigned short)wParam];
keyboard[key].KeyUp();
return 0;

// To use it just do

bool isAHeld =keybard[Key::A].IsHeld();
bool isAReleased =keybard[Key::A].IsReleased();

Be aware that IsPressed() and IsHeld() will reset the value, so the cycle to reset all keys on each frame is no more needed.
