Bit Masking Made Easy – Convert Decimal to Binary (advanced programming)

Bit masking is an advanced programming technique. In this example, I show you how to use a bitmask in C in order to determine the bit pattern of a specific byte (a number or a character).

PROGRAMMING BOOKS
====================
If you want to learn programming in more depth (and also support this channel!) you might think of buying one of my books. I have written books on C programming, Using Pointers in C, Recursion and other programming topics. You can buy my books (paperback or Kindle) on Amazon.

Good luck! And good programming!

The ternary conditional operation returns values — it doesn’t “do” anything [reference 5:30]; however, if you need to perform work based on the result of a given condition, you can encapsulate your code in a statement expression (or is it an expression statement?)or you can encapsulate your code in a block (Blocks.h).

this was so helpful in solving the "bulbs" problem in CS50. Thanks a lot sir!

Thank you that really illustrates the idea

I'd like to see a video about UTF-8 strings in C.

You could have just written “c & mask” without the ternary conditional. That it is shorthand for the traditional if-else clause is not relevant; that it can be abbreviated to just an else clause would be interesting to note, though.

"advanced orogramming" ...you're just saying that to make me feel better aren't you.
