cout 打印错误

Question

I have a variable which is divided into 3 and 5 bits, and i am able to populate to each section ie a and b.

unsigned char a:3,b:5;

How can i print the values of both the section individually. If not how can I print as a whole.

 cout << a << b ;

Please help me out.

Answer 1

union Value
{
    unsigned char char_value;
    struct BitValue
    {   
        unsigned char three_bit:3;
        unsigned char five_bit:5;
    } bit_value;
};

int main()  
{  
    Value tmp;
    tmp.char_value=207;
    cout<<(unsigned int)tmp.bit_value.three_bit<<" "<<(unsigned int)tmp.bit_value.five_bit<<" "<<(unsigned int)tmp.char_value<<endl;
    return 0;
}

Maybe this is answer.
