What does '%' mean in programming?
The % operator is one of the "Arithmetic Operators" in JavaScript, like / , * , + , and - . The % operator returns the remainder of two numbers. It is useful for detecting even/odd numbers (like to make stripes) and for restricting a value to a range (like to wrapping an animated ball around) .
A symbol in computer programming is a primitive data type whose instances have a unique human-readable form. Symbols can be used as identifiers. In some programming languages, they are called atoms. Uniqueness is enforced by holding them in a symbol table.
In computer programming, a sigil (/ˈsɪdʒəl/) is a symbol affixed to a variable name, showing the variable's datatype or scope, usually a prefix, as in $foo , where $ is the sigil. Sigil, from the Latin sigillum, meaning a "little sign", means a sign or image supposedly having magical power.
5 $ # 3 means 'flowers are really good' and II 7 # 3 5 means 'good flowers are available'. Since both the statements have 5, # and 3 in common, $ is unique to the first statement. So by striking out common words, we get the meaning of $. Was this answer helpful?
*= Multiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand. C *= A is equivalent to C = C * A.
The increment operator ++ adds 1 to its operand, and the decrement operator -- subtracts 1 from its operand. Thus − x = x+1; is the same as x++; And similarly − x = x-1; is the same as x--; Both the increment and decrement operators can either precede (prefix) or follow (postfix) the operand.
Ø (or minuscule: ø) is a letter used in the Danish, Norwegian, Faroese, and Southern Sámi languages. It is mostly used as a representation of mid front rounded vowels, such as [ø] ( listen) and [œ] ( listen), except for Southern Sámi where it is used as an [oe] diphthong.

Inserting ASCII characters
To insert an ASCII character, press and hold down ALT while typing the character code. For example, to insert the degree (º) symbol, press and hold down ALT while typing 0176 on the numeric keypad. You must use the numeric keypad to type the numbers, and not the keyboard.
The dollar sign ($) and the underscore (_) characters are JavaScript identifiers, which just means that they identify an object in the same way a name would. The objects they identify include things such as variables, functions, properties, events, and objects.
Why do we put $() dollar?
$() – dollar function
The dollar sign ( $ ) is also used as a shortcut to the function document. getElementById() . The $ is being used as an alternative since this function references a DOM element if we pass an element's id and now is used frequently in JavaScript to serve the purpose.
$$ is an escape; it is replaced with a single $. $identifier names a substitution placeholder matching a mapping key of "identifier" . By default, "identifier" must spell a Python identifier. The first non-identifier character after the $ character terminates this placeholder specification.
143: I Love You
This one is easy. I (1) Love (4) You (3).
- 1234 (1 thing 2 say 3 words 4 you (I love you))
- 143 (I love you (the number of letters in each word))
- 14344 (I love you very much (number of letters in each word))
- 1437 (I love you forever (number of letters in each word))
- 381 (I love you (3 words, 8 letters, 1 meaning))

The addition assignment ( += ) operator adds the value of the right operand to a variable and assigns the result to the variable.
Dec 14, 2020. The Python += operator lets you add two values together and assign the resultant value to a variable. This operator is often referred to as the addition assignment operator. It is shorter than adding two numbers together and then assigning the resulting value using both a + and an = sign separately.
Using += in Java Loops
The += operator can also be used with for loop: for(int i=0;i<10;i+=2) { System. out. println(i); } The value of i is incremented by 2 at each iteration.
It's just two different ways of writing the same thing. i++ is just a shortcut for i += 1 , which itself is a shortcut for i = i + 1 . These all do the same thing, and it's just a question of how explicit you want to be.
The \0 is treated as NULL Character. It is used to mark the end of the string in C. In C, string is a pointer pointing to array of characters with \0 at the end. So following will be valid representation of strings in C.
What does i += 1 mean in C++?
i += 1 produces i after incrementing (like a preincrement), while i++ produces i before incrementing. Thus, int a = 0, b = 0; cout << (a+=1) << " " << b++ << endl; prints 1 0 .
– “ö” as in blöd is like an English person saying “burn” Make the sound “a” as in the word “may” and then make your lips into an “o” shape.
The letter o with umlaut (ö) appears in the German alphabet. It represents the umlauted form of o, resulting in [œ] or [ø]. The letter is often collated together with o in the German alphabet, but there are exceptions which collate it like oe or OE.
The Finnish name for Å is ruotsalainen O ("Swedish O"), and is pronounced identically to O, which has the value [o̞].
The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. In other words, x is one of the objects in the collection of (possibly many) objects in the set A.
| Name | Read as | Example(s) |
|---|---|---|
| ≡ | definition | (a+b)2≡a2+2ab+b2 |
| ≈ | approximately equal | √2≈1.41 |
| ≠ | inequation | 1+1≠3 |
| < | strict inequality | 4<5 |
Put simply. & means the address-of, you will see that in placeholders for functions to modify the parameter variable as in C, parameter variables are passed by value, using the ampersand means to pass by reference. * means the dereference of a pointer variable, meaning to get the value of that pointer variable.
The characters “U+” are an ASCIIfied version of the MULTISET UNION “⊎” U+228E character (the U-like union symbol with a plus sign inside it), which was meant to symbolize Unicode as the union of character sets. See Kenneth Whistler's explanation in the Unicode mailing list.
- Press the Alt key and then type the four-digit Unicode value. ...
- If you're working with Microsoft Word, WordPad, Outlook, or another Microsoft app, you can type in the Unicode value and then type Alt-X.
- You can also press the Control key plus a symbol, and then the letter you want to accent.
To use an Alt code, press and hold down the Alt key and type the code using the numeric key pad on the right side of your keyboard. If you do not have a numeric keypad, copy and paste the symbols from this page, or go back try another typing method.
What does $this mean in JavaScript?
In JavaScript, the this keyword refers to an object. Which object depends on how this is being invoked (used or called). The this keyword refers to different objects depending on how it is used: In an object method, this refers to the object.
$(this) is a jQuery wrapper around that element that enables usage of jQuery methods. jQuery calls the callback using apply() to bind this . Calling jQuery a second time (which is a mistake) on the result of $(this) returns an new jQuery object based on the same selector as the first one.
The Prefix Operator
++i is called a prefix operator. This means that the value of the variable is incremented before it is used in the expression. For example, consider the following code: let i = 0;console.log(++i); // Prints 1console.log(i); // Prints 1.
What does $$ (dollar dollar or double dollar) means in PHP ? The $x (single dollar) is the normal variable with the name x that stores any value like string, integer, float, etc. The $$x (double dollar) is a reference variable that stores the value which can be accessed by using the $ symbol before the $x value.
PHP $ and $$ Variables. The $var (single dollar) is a normal variable with the name var that stores any value like string, integer, float, etc. The $$var (double dollar) is a reference variable that stores the value of the $variable inside it. To understand the difference better, let's see some examples.
That dollar sign means: we're in the system shell, i.e the program that you're put into as soon as you open the Terminal app. The dollar sign is often the symbol used to signify where you can begin typing in commands (you should see a blinking cursor there).
In Python these operators won't work. In Python variables are just labels to objects in memory. In Python numeric objects are immutable. Hence by a++ (if a=10) we are trying to increment value of 10 object to 11 which is not allowed.
The == operator compares the value or equality of two objects, whereas the Python is operator checks whether two variables point to the same object in memory.
Python also allows you to index from the end of the list using a negative number, where [-1] returns the last element. This is super-useful since it means you don't have to programmatically find out the length of the iterable in order to work with elements at the end of it.
1423 – “I want to die” (one letter in “I,” four in “want,” 2=to, three letters in “die”)
What does 721 mean?
721 = I love you (8 letters, 3 words, 1 meaning) 381 = I love you (3 words, 8 letters, 1 meaning) 721 is a form of shorthand typically used in texts or instant messaging. It also allows the speaker to say "I love you" without suffering the embarrassment felt by some (particularly men) when saying those words.
143 is based on the number of letters in each word of the phrase: I (1), love (4), you (3). The shorthand, as the story goes, dates back to the early 1900s from Minot's Ledge lighthouse off the coast of Cohasset, Massachusetts.
Text message code for I love you, 459 corresponds to each of the first letters in "I love you," I=4, L=5, and Y=9 on a cell phone dial pad.

For many years, the yellow rose was considered a symbol of infidelity and cheating. The legend obviously has many variations, but its meaning remains the same: yellow roses are a sign of betrayal and separation.
Coming up to the 18th century, the rose now symbolizes forbidden love. The flowers were used as a means of communication between lovers who were forced apart by the standards of the societies they lived in.
9 ROSES. A symbol of eternal love. You would often give this exact number of roses to those you wish to spend the rest of life with. In Chinese, nine is a hom*onym of long-lasting.
> is a symbol that means “greater than.” In math, it shows one value is larger than another (4 > 3).
Less than or equal to.
What does the += operator do?
The += operator adds the value on its right to the variable or property on its left, and assigns the result to the variable or property on its left.
modulus: An operator that works on integers and yields the remainder when one number is divided by another. In Java it is denoted with a percent sign(%).
i++ increment the variable i by 1. It is the equivalent to i = i + 1. i– decrements (decreases) the variable i by 1.
Increment in java is performed in two ways, 1) Post-Increment (i++): we use i++ in our statement if we want to use the current value, and then we want to increment the value of i by 1. 2) Pre-Increment(++i): We use ++i in our statement if we want to increment the value of i by 1 and then use it in our statement.
Today, the Union Jack is the official flag of the United Kingdom, which includes England and Wales, Scotland, and Northern Ireland. The flag for the United Kingdom emoji was added as part of Emoji 1.0 in 2015 based on Unicode's earlier, two-letter country codes.
The butterfly emoji represents the butterfly, as well as the symbolism associated with it: positive transformations, hope during a dark time, and new beginnings.
Asterisk. Meaning: You're afraid the person isn't as cool as you. The main reason people use asterisks in a text is to censor a word, for example: "I like deep-fried sandwiches so my friends call me the C*** of Monte Cristo.
This is Backus-Naur Form (BNF) notation describing the language. ::= in this context means is defined as. For example, in the Python language documentation you refer to, an identifier is defined as a letter or an underscore, followed by a letter, a digit or an underscore.
%s specifically is used to perform concatenation of strings together. It allows us to format a value inside a string. It is used to incorporate another string within a string. It automatically provides type conversion from value to string.
The Python += operator performs an addition operator and then assigns the result of the operation to a variable. The += operator is an example of a Python assignment operator. This operator is called the addition assignment operator.
What does == mean in C++?
The equal-to operator ( == ) returns true if both operands have the same value; otherwise, it returns false . The not-equal-to operator ( !=
i = i + 1 reassigns i , i += 1 increments i by 1.
