What does 'unsigned temp:3' mean? [duplicate] http://stackoverflow.com/questions/2950029/what-does-unsigned-temp3-mean this question This construct specifies the length in bits for each field. The advantage of this is that you can control.. sizes of the fields inside. In your case size of op is 32 bits that is sizeof op is 4 . The size always gets rounded up to.. xxx yy construct. That means struct A unsigned a 4 4 bits unsigned b 4 4 bits same group 4 4 is rounded to 8 bits unsigned..
