hmm... for question number 1.. .. u can understand more easliy with the following examlple
#include<stdio.h> // 1. #include<stdio.h> #pragma pack(1) struct value { int a; int bit3: 4; int bit4: 4; }; #pragma pack() int main() { struct value bit; printf("%d",sizeof(bit)); system("pause"); return 0; } here size is 40 bits.(take int of 4 bytes).. so 5 bytes... if you don't use pragma directives... compiler assignes location as multiple of 4 for fast processing.. google it you'll find for question number 2: all your structure elements are signed so bit 1 cannot take any int value as it has got only 1 bit.. so if you declare bit1 as unsigned you will get fine output.. in bit3 and bit4 ..you will get fine answer if value from(0 to 7) i hope you got it for question number 3; ya you can use bit fields in union..
