Thank you!

Thank you!

Happy to hear!

You're very welcome!

You are welcomed!

me too lol its need alot of almonds for that 😜😜

I understood the 2nd compliment but the 1st one was never explained

The number and his complement must equal 0, if we applied the same rule for binary, we will end with number like, 111111 ,so we add 1(the second complement) to make it 0. Note: after adding 1, the left most 1 is discarded.

Glad it helped!

Yes, you're right. A bit is a simple representation of 0 or 1. it's a two-state device. Either 0, or 1. I am not sure how a transistor works, though. When you combine 8 bits, you get a Byte. Now you have 256 possible combinations. Here's one combination 00010010 and here's another one: 00000001. Each combination is determined to represent a character, for example "A" or "4". That's how bits are combined into Bytes that are combined together to represent all of the required characters in all languages.

@@morsagmon9309 thank you so much sir....im also confused in term that an integer can store 65536 numbers how is it possible? although we know that integer can store 2 bytes which is equal to 16 bits means 16 zeros or ones. but what is 65536 numbers??

@@basharathussain5720 16 bits offers 65536 combinations: 0000000000000001 0000000000000011 0000000000000010 0000000000001011 0000011010110001 0011111111110001 ... ... ... If you have 16 bits, you can combine 2^16 combinations (2 to the power of 16) = 65536. If you have 2 bits only, you can combine 4 combinations (2^2 = 4). Here they are: 00 11 01 10

@@morsagmon9309 sir i have an assignment in unversity and im in tense and so confused.....because of not understandin guestions.

Question #01 An Array has a mix of 0s and 1s representing False and True Boolean values. Write function AllTrue() that returns 1 when all the entries in the array are true, and 0 when at least one of the entry in the array is false. Do Not Use Selection Structures. Question #02 An Array has a mix of 0s and 1s representing False and True Boolean values. Write function AnyTrue() that returns 0 when all the entries in the array are false, and 1 when at least one of the entry in the array is true. Do Not Use Selection Structures. Question #03 Allow the user to input the xy co-ordinates for n number of points in a two-dimensional co-ordinate system. Write a function to evaluate if all those points exist on the same straight line. You can use 2 single dimension arrays of length n. Question #04* Write a program that uses a function decoder(). Write the decoder() is such a way that it accepts 3 Boolean inputs, selects one of the 2 output bits, and writes a 0 or 1 (as provided by the user) on the selected bit. Question #05* Write a program that uses a function decoder(). Write the decoder() is such a way that it accepts 4 Boolean inputs, selects one of the 2 output bits, and writes a 0 or 1 (as provided by the user) on the selected bit. Question #06* Write a program that uses a function decoder(). Write the decoder() is such a way that it accepts variable length (e.g. 3, 4, 5) Boolean inputs, selects one of the 2 output bits, and writes a 0 or 1 (as provided by the user) on the selected bit. *An  × 2 decoder is an electronic device. Its name is derived from the fact that it has  number of input lines and 2 output lines. Out of these 2 outlines only one is selected based on the Boolean inputs on  lines.

As a developer, the more you understand how things work under the cover - the greater your toolbox to write efficient solutions to various problems. For example, in the following Blog post, I explain how to take advantage of bits and bytes for a highly efficient and convenient technique: bit-wise enumerations: www.morsagmon.com/blog/Excel-VBA-Bit-Wise-Enumerations Similarly, if a scientist wants to develop a drug to handle immune issues, he needs to understand how the immune system works (not they really do, but that is another discussion...).

Hi. Most people should not care. A programmer should understand how things work, and sometimes may even need to implement a program that makes use of the bits & bytes of things. It's like a gardener that needs to understand about soil quality, pollination, etc. - not just stick a plant in the dirt and pour water...

sir you are great! thank you so much sir

Most welcome
