Using bitwise operators in switch case

Question

I have enum,
enum ENUM_MSG_TEXT_CHANGE {COLOR=0,SIZE,UNDERLINE};

void Func(int nChange)
{
switch(nChange)
{
case COLOR:break;
case SIZE:break;
case COLOR|SIZE: break
}

}

case SIZE: and case COLOR|SIZE both gives value 1, so I am getting error error C2196: case value '1' already used. how to differenciate these two cases in switch case?

Answer 1

Start the enumeration with COLOR=1

Answer 2

Try this

enum ENUM_MSG_TEXT_CHANGE { COLOR = 1, SIZE = 2, UNDERLINE = 4, ITALIC = 8, UGLY = 16, PRETTY = 32, AWESOME = 64 };
