C Programming Tutorial 2-10: Bitwise Operators

[himerius2007]

int x = 193;

int y = x ^ 0xf0;

Y is: 49

Thank you very much.Pretty helpful as I'm interested in embedded C

May not use bitwise unless you're programming for embedded?

Bullshit, you try making a SDL Window using double buffers and no boarders without using a bitwise OR (or any function using multiple flags at once for that matter)

Thank you so very much! Makes so much sense now! :) Thank you!

Thanks a lot. This was really helpful.

great job now i can score more in tommorow test

Great tutorial...especially noting where and when these operations are used in the programming world. Embedded programming is where I want to go.

Exclusive OR slide...seems y = 62 /* 0011 0001 */ should be 49? bit 6(32), bit 5(16) and bit 0(1)

these are used in exams on uni's :(

What if a variable's value cannot be held in a single byte?

How then are the comparing bits lined up between the memory location of two variables when using these operators?

Wow, thanks for the tutorial. Currently learning Objective-C and helped cleared up a lot of things!

great tutorial xD

Thank you for this video. Clears away some of the fog.

Just wanted to say thanks. Your video did for me in 10 minutes what the book titled "Deitel & Deitels C How To Program" couldn't do in 20 pages.

[GamingJediPwns]

Thank you, that really helped.

bear in mind you can also use bitwise ops in the following fashion.

variable |= 10; // logical OR with 1010 (binary)

variable ^= 10;

variable >>= 2; //shift

etc...

[0121ryanh117]

I use bitwise ops for emulation.

[xfx1118]

Very helpful, but some exampled would have been nice, simple things like altering letter case by changing the 6th bit...

thanks

I get it now! thanks a bunch
