The answer is according to 16bit operating system
But if the system is 32 bit so answer would be 20 and of the system is working on 64 bit like vscode, gdb etc the answer would be 24 .you can check it out

To disregard 'alignment/padding' and to obtain the same answer as the instructor, use these flags:
GCC: `-fpack-struct`
Clang: `-fpack-struct=1`

or surround code with:
`pragma pack(1) // disable padding`
`pragma pack() // enable padding`

Fill in the blanks to declare a union holding an integer, a float and a char. Then, declare a union variable and initialize its char member.
union
values {

int i_val;

float f_val;

char c_val;

};



union
val;

val
.c_val = 'a';

what is about the concept of padding? this struct should have then in a 32-bit architecture the size of 20 bite [ 10 bits+ 2bits(padding) +8bits]

[uditnousran]

Why didn’t we consider padding concept in this question sir??

[christopherhenry]

Why u didn't used structure padding in this

if we took padding into consideration then the answer should be 20 or 24 ?
