Bit Fields In C & C++

[@hindiistoriess]

Thank you 🙏🏻 for explaining in detail... Now I understood fully about bit fields

[@treyquattro]

I appreciate the work you put into these videos and your professorial style. The videos are a great resource for newbies and also as a refresher for some of us who like to keep our memories refreshed!

[@CppNuts]

Thanks man!!

[@janupenaganti4951]

I have started my career in Embedded Systems, this topic is really helpful for me. Thank you!!

[@nishantgarg5324]

Nice illustrate. Keep it up.

Thanks Dude!!

[@sabanaafrose7293]

Superb... Keep doing... The way you explained the flow and the sequence ... Everything made me hit like ..if I could I would hit it many times.... Thank a lot

[@ViratKohli18_Lovers]

You explained it very well sir. I understood everything about bit field.

[@CppNuts]

That's great!!

[@pandemade3875]

Thank you so much! This really helps me understand bit field in more detail! Thank you!

[@CppNuts]

Glad that it helped.

8:51 sir, Why structural packing doesn't work in the above example it still give 8 bytes of size
On adding #pragma pack(1)

[@shibisaketh]

unsigned int day : 5;
unsigned int month : 4;
int year : 22;
So can reduce the size again.
Size : 4

[@CppNuts]

Yes you can further use the same int for 1 Bit because 5+4+22 = 31 and int is 32 bits.

Congratulations from Brazil.

Thanks man!!

It was very helpful and I request to upload a tutorial regarding forward declaration in c++ in details and with depth analysis.thanks .

I am trying my best to upload as much as i can but i will keep this suggestion in my mind thanks dude!! :)

struct date {
unsigned char day : 5 ;
unsigned char month : 4 ;
unsigned char year ;
} ;
printf("sizeof struct date : %d
",sizeof(struct date)) ; // output is 3
i'm using gcc default compilation .

[@CppNuts]

Year one byte
Day + month is 2 bytes, because 5+4 is 9 bits which is more than one byte.

[@justcurious1940]

@@CppNuts Thank u for replying, my confusion was that the size of( struct date) is not a power of 2 or a multiple of 2, I thought that objects in C always occupies a space in memory that is either a power of 2 or a multiple of 2.

[@CppNuts]

That is multiple of biggest data member in class or struct.

[@justcurious1940]

@@CppNuts yes, Thank u I get it now.Great video by the way, so much information gained.

[@shiwanisingh3152]

Very helpful sir
Thank you sir

[@CppNuts]

Most welcome!!

[@shivamsaxena5854]

#include
#include
struct d0
{
char vo : 3;
int v1 : 7;
};
int main()
{
printf("%d", sizeof(struct d0));
return 0;
}
I thought that I shall get 4 bytes as output as 32 bits (size of larger data type i.e; int) are enough to store 3 bits of char and 7 bits of int data type, But instead, I'm getting 8 bytes as output.
Please tell me why I am getting so?
Please answer @CppNuts

How will allocate 16 bytes or 32 bytes in bit fields or large size?
I need this very much.Please explain

[@CppNuts]

Please explain more, couldn't understand your question?

[@mdirshadalam2617]

@@CppNuts Is there any restriction for allocating bit in bit fields?
Means, how many bits to allocate in bit field or no restriction.

[@CppNuts]

Yes it is max of the type used. For more check this stackoverflow.com/questions/14553632/maximum-size-of-a-bit-field-in-c-or-c

[@_shubham_kumar]

Great video. But I don't understand why we can't have static variables with bit fields?

[@CppNuts]

Why do you want that?

[@mukundshahiitr7113]

Nice explaination☺☺

[@CppNuts]

It's my pleasure

[@SYALUS3]

Very good explanatuion... But one doubt actually we couldn't use that saved memory. Then why....

[@CppNuts]

Notice that when we didn't use bit fields size was 12 but when we used bit fields then size became 8.
