I need to calculate the % of Grand Total on Microsoft Excel, but can't for the life of me remember how to do that. Help would be
vagabundo [1.1K]

Answer:

You need to first use the Sum function to add up all the costs of September.

Then divide each September cost by the grand total that you got. After that format the last column to be percentages.

Look at the attached file for the formulas used.

How each programming language differs in terms of constructs, techniques, use and requirements?
Anuta_ua [19.1K]

Programming languages are (designed to be) easily used by machines, but not people.

Natural languages (like English) are easily used by humans, but not machines.

Programming languages are unambiguous, while natural languages are often multiply ambiguous and require interpretation in context to be fully understood (also why it’s so hard to get machines to understand them). Natural languages are also creative and allow poetry, metaphor and other interpretations. Programming does allow some variation in style, but the meaning is not flexible.

Lojban (Wikipedia) is an artificial language designed to try to bridge the gap between these two types of languages. It is specifically unambiguous yet something that a human can pronounce and even speak meaningfully. It can be considered a somewhat successful experiment yet limited in functionality in some ways in both domains (and not a real substitute for a normal programming language, but perhaps useful as an interface).

Natural languages consist of sentences, usually declarative sentences expressing information in a sequence. Programming languages typically are not declarative but procedural, giving instructions to the machine to do something (like commands in natural languages). Rarely, programming languages are declarative, such as Prolog, where statements are given to the computer, then the evaluation consists of finding possible solutions that match those statements (generate a list of words based on possible combinations of letters as defined just by letter-combining rules, for example).

The vocabulary of natural languages is filled with conceptual terms. The vocabulary of programming languages is generally only ‘grammatical’/functional ‘words’ like basic comments, plus various custom-named things like variables and functions. There are no words like you’d look up in a dictionary to express something like ‘love’ or ‘happy’ or ‘sing’.

The grammatical structures vary in more ways than are easy to list here. But some of the most obvious factors are that words don’t have separable parts in programming languages (like English cat-s to form a plural) [=no morphology], and that via brackets, line breaks or other markers, embedding tends to be overtly and clearly marked on both sides for the parser in programming languages, whereas spoken languages usually only have one word (like “that”) linking embedded sentences, and sometimes no word at all. This is another reason that parsing human languages is so hard on a computer.

You could also look at Hockett’s design features and see which apply to programming languages: What is the difference between human and animal language?

In a very general sense, programming languages aren’t used for bidirectional communication and may not properly be considered “languages” in the same sense as natural languages. Just looking at Hockett’s features, they’re completely distinct in being written only, do not involve interchangeability between the speaker and hearer, do not have ‘duality of patterning’ meaning multiple layers of structure as sounds vs. phrases (phonology vs. syntax), and are not transmitted culturally (well, maybe). It’s just very hard to even try to make the comparison.

Most fundamentally, it is worth asking if programming languages even have meaning, or if they are just instructions. This is similar to the Chinese room thought experiment— given a book of instructions for how to translate Chinese, but without actually understanding it, would a human (or computer) with that book be considered to “know” Chinese? Probably not. A computer doesn’t “know” anything, it just does what the instructions tell it to. Therefore, programming languages have no semantics/meaning. They just are instructions, which translate into electronic signals, nothing more.

Uses of the following button in a keyboard: Prt SC, Home, Shift, Tab, Pg Up.​
creativ13 [48]

Answer:

This Print Screen key is used to take the screenshots of all that is appearing on the screen, and this can then be pasted in paint and saved in some location of the computer.

The Home key takes the cursor from the current position to the top left, or the start of the file.

Shift: There are two shift keys. And they are used to print the character in the capital. And when the caps lock is busy it can be used to print in lower case. It is also used together with arrow keys to select a part of the text.

Tab: This key moves the cursor from the current location to the location which we know as tab stops ( and the very next one).

Pg Up:​ The page up is being used for scrolling up, and the distance to which limit the scrolling will take place depends upon the application you are working on.

Explanation:

Please check the answer.
