Jul 8, 2013 · Modulus operator gives you the result in 'reduced residue system'. For example for mod 5 there are 5 integers counted: 0,1,2,3,4. In fact 19=12=5=-2=-9 (mod 7). The main difference that the answer is given by programming languages by 'reduced residue system'.

Oct 2, 2024 · Note that the result of the % operator is equal to x – (x / y) * y and that if y is zero, a DivideByZeroException is thrown. If x and y are non-integer values x % y is computed as x – n * y, where n is the largest possible integer that is less than or equal to x / y (more details in the C# 4.0 Specification in section 7.8.3 Remainder operator).

Aug 31, 2009 · You can find a table of operator precedence here. This is for the C language, but it should be similar for most other languages. There is also operator associativity. This is (basically) the order which operators of the same type are evaluated. Most of the ones you are used to will be left associative. For example: 4 * 5 * 6 * 7

This is a new operator that is coming to Python 3.8 and actually had a role in BDFL Guido van Rossum's early retirement. Formally, the operator allows what's called an "assignment expression". Informally, the operator is referred to as the "walrus operator". It allows assignment while also evaluating an expression. So this:

The ~ operator in C++ (and other C-like languages like C and Java) performs a bitwise NOT operation - all the 1 bits in the operand are set to 0 and all the 0 bits in the operand are set to 1. In other words, it creates the complement of the original number.

^ is the Python bitwise XOR operator. It is how you spell XOR in python: >>> 0 ^ 0 0 >>> 0 ^ 1 1 >>> 1 ^ 0 1 >>> 1 ^ 1 0 XOR stands for exclusive OR. It is used in cryptography because it let's you 'flip' the bits using a mask in a reversable operation: >>> 10 ^ 5 15 >>> 15 ^ 5 10 where 5 is the mask; (input XOR mask) XOR mask gives you the ...

In computer programming languages, the equals sign typically denotes either a boolean operator to test equality of values (e.g. as in Pascal or Eiffel), which is consistent with the symbol's usage in mathematics, or an assignment operator (e.g. as in C-like languages). Languages making the former choice often use a colon-equals (:=) or ≔ to ...

Feb 25, 2013 · It was also taken into use in APL in early 1960's and incorporated into PL/I at about the same time as the OR operator and, doubled, as the concatenation operator. John Warner Backus (December 3, 1924 – March 17, 2007) was an American computer scientist. He directed the team that invented the first widely used high-level programming language ...

Dec 5, 2021 · How can we write "not equal" in c? Standard C has alternate spellings macros in <iso646.h> (since C94) including not_eq.

Just to save future generations on any confusion here. It is the "conditional operator". It just happens to be a ternary operator, of which there is only one in C and C++. There are lots of unary (~, !, -) and binary (+, -, <<) operators in C/C++ as well. Neato! –
