I have to admit this: This is the single tutorial I ever watched on KZbin till date where I understood 100% without putting any stress on my head. No words to describe the excellence of this masterpiece.

[@diptisarkar4849]

i came across this channel just some time ago and the videos were so good that i fell in love with them and watched all the 9 videos in this playlist only to come to the comment section to find that the creator has passed away. It is such a shame that he is not with us anymore. i am probably too late to say this, but RIP. WE LOVE YOU.

[@SatishSingh-mk7jq]

You are the best there has been on youtube ! RIP for fellow viewers, at 20:00 , when he is explaining how a stored signed integer is interpreted by the system to print it... he takes 2's complement. i.e. in order to store the -ve integer, you convert it to 2's complement and store it... As WELL AS,.... in order to print it .. again it converts that stored 2's complement to (once more) 2's complement of itself. Hence 2's complement operation is applied both direction while storing as well as fetching for NEGATIVE integers

[@vivekanandhiremath423]

1 can be represented in 4 bit binary as (2's complement) 1111 15 is also represented as 1111. So, how does CPU differentiate between 15 and -1 when it gets values from memory?

[@varunaggarwal1995]

1111 is not the real value of -1(it is kind of representation to represent -ve stuff), here most significant 1 is used to represent that it is a signed integer, to calculate real value of -1 calculate 2's complement of remaining 3 bits(leave out the MSB) which is 001. So, MSB represents sign and later digits when 2's complemented represents magnitude.

[@sirnawaz]

Good tutorial. However, pedantically speaking: - In C (and C++), a byte is NOT necessarily 8 bits. It could be other than 8 bits as well. That is the reason why these two languages have defined a macro called CHAR_BIT whose value happens to be 8 on most machines but there are machines where it is different from 8. Interesting, isn't it? Note that a byte is defined to be "the basic addressable" unit which means its size depends on the size of the execution character set on a given machine. - sizeof is NOT a function, it is a *compile-time* operator (though in C99, it is a runtime operator as well). Please let me know if you've any doubt/concern/question. I'd like to help you to improve the content of these tutorials. :-)

[@mycodeschool]

Sarfaraz Nawaz bit and byte are units. It has nothing to do with a programming language or machine architecture. 1 byte = 8 bits just the way 1 Kilo-meter = 1000 meters.

[@sirnawaz]

mycodeschool Not really. The size of a byte depends on the machine, hence in C and C++, the size of a byte is defined to be implementation-defined, which is why C and C++ compilers are "required" to define a macro called CHAR_BIT. Otherwise, if 1 byte is always 8 bits, then such a macro would not be required by the language specification. Have a look at the wikipedia (at least) before you comment further. It says, "The C standard requires that the char integral data type is capable of holding at least 256 different values, and is represented by at least 8 bits (clause 5.2.4.2.1). Various implementations of C and C++ reserve 8, 9, 16, 32, or 36 bits for the storage of a byte.[10][11] The actual number of bits in a particular implementation is documented as CHAR_BIT as implemented in the limits.h file. Java's primitive byte data type is always defined as consisting of 8 bits and being a signed data type, holding values from −128 to 127." en.wikipedia.org/wiki/Byte I don't trust Wikipedia usually but this information is 100% accurate! I'm sure you're surprised to know that byte is NOT necessarily 8 bits. (I know that is what is taught in colleges...even in IITs and IIITHs..but they're WRONG!).

[@sirnawaz]

+Nick G . 1 byte == 8 bits is true for most systems. However, it is not true for all systems, and the two languages C and C++ definitely do NOT define "1 byte" to be "8 bits". In these languages (and at machine level), a byte is defined to be smallest "addressable"' unit and thus it does not restrict the number of bits in it to be 8. It could be 9 as well. In fact, there existed some systems where 1 byte == 9 bits. Please do some research before commenting further. stackoverflow.com/questions/5516044/system-where-1-byte-8-bit

[@NoOne-ky1er]

C/C++ might had been different in definition of 1 byte. But 1 bit does have a physical significance as 0 or 1. When flip-flop stores a data, we call it bit.

[@sirnawaz]

@@NoOne-ky1er What is the relevance of that with regards to what I said here?
