The meaning in computing is similar. It distinguishes a single value like an integer or float from a data structure like an array. This distinction is very prominent in Perl, where the $ sigil (which resembles an 's') is used to denote a scalar variable and an @ sigil (which ...Fri, 24 Apr 2026 04:22:00 GMThttps://softwareengineering.stackexchange.com/questions/394525/what-are-the-scalar-fields-and-composite-fields-in-javaThe terms 'scalar type' or 'scalar field' are usually used to contrast them with compound types/fields. A compound type is easiest to define and it is a type that contains multiple distinct elements. These elements can have the same type, in which case the compound is an array or a list, or different types, in which case the compound is typically a struct or a class. A scalar type is a type ...Thu, 19 Mar 2026 14:09:00 GMThttps://softwareengineering.stackexchange.com/questions/445775/recommended-generic-approach-to-checking-scalar-field-presence-in-protobuf-3There are several questions related to presence field tracking of scalar fields in protobuf 3, but I didn't find any with generic default approach recommendation.Wed, 22 Apr 2026 09:54:00 GMThttps://softwareengineering.stackexchange.com/questions/361392/if-you-follow-the-rule-of-zero-how-will-you-debug-the-construction-of-an-objectMost noticeable is if the destructor is called as part of a deletion on dynamic memory (delete). In the disassembly, one will see an actual function call to an address associated with some_type::scalar deleting destructor. Once a module (EXE or DLL) has been loaded into the process space, one can set a breakpoint at its disassembly address.Sat, 11 Apr 2026 16:55:00 GMThttps://softwareengineering.stackexchange.com/questions/348783/why-exactly-does-java-not-allow-numeric-conditionals-like-if5-if-c-does0 Well, every scalar type in C, pointer, boolean (since C99), number (floating-point or not) and enumeration (due to direct mapping to numbers) has a "natural" falsey value, so that's good enough for any conditional expression.Sat, 18 Apr 2026 18:34:00 GMThttps://softwareengineering.stackexchange.com/questions/356847/paradigm-for-handling-list-of-things-or-single-elements@KilianFoth: I don't think this applies here. "Composite design pattern" would require to wrap the passed parameter in an additional class hierarchy, but additional wrappers is exactly what the OP tries to avoid. Moreover, in Python one can already use a list or a scalar in exchange when calling a function, that is syntactically ok.Tue, 14 Apr 2026 08:09:00 GMThttps://softwareengineering.stackexchange.com/questions/139747/what-is-meant-by-a-primitive-data-typeIt kind of depends on the language. For example, in languages like C and C++, you have a number of built-in scalar types - int, float, double, char, etc. These are "primitive" in the sense that they cannot be decomposed into simpler components. From these basic types you can define new types - pointer types, array types, struct types, union types, etc. Then you have a language like old-school ...Sun, 19 Apr 2026 12:06:00 GMThttps://softwareengineering.stackexchange.com/questions/207308/java-why-do-we-call-an-array-a-vectorThe most famous vector space is R^n, the set of "arrays" of numbers with element-wise addition and multiplication. The set of real functions is also a vector space, but usually people don't think of functions as arrays. An array of characters wouldn't be a vector space, since there is no obvious choice of addition and multiplication. In mathematics jargon, an array is a tuple or a finite ...Sat, 18 Apr 2026 16:18:00 GMThttps://softwareengineering.stackexchange.com/questions/266540/passing-parameters-that-need-to-be-copied-by-value-or-const-reference@rwong: using "const reference" for function parameters in C++ is not more or less idiomatic than just passing parameters by value. It is typically (but not exclusively) used for passing "big" objects to avoid unnecessary copying, but in the example above, a copy is made in both cases.Thu, 16 Apr 2026 18:29:00 GMThttps://softwareengineering.stackexchange.com/questions/458882/is-there-a-reason-replace-conditional-with-table-isnt-a-standard-refactoringfor speed you have to use low level arrays, not collections like lists and maps. Also, you have to avoid creating objects, unless there is a scalar optimization done by JIT.Wed, 22 Apr 2026 14:40:00 GMT
