What is the size of this Structure

Fri May 08, 2009 7:09 am

Assuming 32 bit compiler, Unsigned int will take 4 bytes

Code:
Struct mystruct
{
   unsigned int bit0 : 1;
   unsigned int bit0 : 1;
   unsigned int bit0 : 1;
   unsigned int bit0 : 1;
   unsigned int bit0 : 1;
   unsigned int bit0 : 1;
   unsigned int bit0 : 1;
   unsigned int bit0 : 1;
}a;

I have the doubt,whether the sizeof structure is 1 byte or 4 byte?
Is sizeof(a)=1 or sizeof(a)=4?

I have compiled the progrma and printed the sizeof(a).It is 1 byte.Not 4 bytes. Why is this so..
