Null coalescing operator. The null coalescing operator is a binary operator that is part of the syntax for a basic conditional expression in several programming languages, such as (in alphabetical order): C# [ 1] since version 2.0, [ 2] Dart [ 3] since version 1.12.0, [ 4] PHP since version 7.0.0, [ 5] Perl since version 5.10 as logical defined ...
String literal. A string literal or anonymous string is a literal for a string value in the source code of a computer program. Modern programming languages commonly use a quoted sequence of characters, formally "bracketed delimiters", as in , where is a string literal with value. Methods such as escape sequences can be used to avoid the problem ...
Naming convention (programming) In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers which denote variables, types, functions, and other entities in source code and documentation . Reasons for using a naming convention (as opposed to allowing programmers to choose any ...
Stack Overflow. Stack Overflow is a question-and-answer website for computer programmers. It is the flagship site of the Stack Exchange Network. [ 2][ 3][ 4] It was created in 2008 by Jeff Atwood and Joel Spolsky. [ 5][ 6] It features questions and answers on certain computer programming topics. [ 7][ 8][ 9] It was created to be a more open ...
C ( pronounced / ˈsiː / – like the letter c) [ 6 ] is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems code (especially in kernels [ 7 ...
Equality is used in many programming language constructs and data types. It is used to test if an element already exists in a set, or to access to a value through a key.. It is used in switch statements to dispatch the control flow to the correct branch, and during the unification process in logic programmi
For example, suppose that a program defines two types, A and B, where B is a subtype of A. If the program tries to convert a value of type A to type B, which is known as downcasting, then the operation is legal only if the value being converted is actually a value of type B. Thus, a dynamic check is needed to verify that the operation is safe.
Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [ 70] and metaobjects ). [ 71] Many other paradigms are supported via extensions, including design by ...
