Common examples of array slicing are extracting a substring from a string of characters, the "ell" in "hello", extracting a row or column from a two-dimensional array, or extracting a vector from a matrix. Depending on the programming language, an array slice can be made out of non-consecutive
Dynamic arrays are available as "slices", denoted []T for some type T. These have a length and a capacity specifying when new memory needs to be allocated to expand the array. Several slices may share their underlying memory. [37] [61] [62] Pointers are available for all types, and the pointer-to-T type is denoted *T.
In mathematics and in computer programming, a variadic function is a function of indefinite arity, i.e., one which accepts a variable number of arguments.Support for variadic functions differs widely among programming languages.
The term string also does not always refer to a sequence of Unicode characters, instead referring to a sequence of bytes. For example, x86-64 has string instructions to move, set, search, or compare a sequence of items, where an item could be 1, 2, 4, or 8 bytes long. [26]
In computer programming, an anonymous function (function literal, expression or block) is a function definition that is not bound to an identifier.Anonymous functions are often arguments being passed to higher-order functions or used for constructing the result of a higher-order function that needs to return a function.

A bitwise AND is a binary operation that takes two equal-length binary representations and performs the logical AND operation on each pair of the corresponding bits. Thus, if both bits in the compared position are 1, the bit in the resulting binary representation is 1 (1 × 1 = 1); otherwise, the result is 0 (1 × 0 = 0 and 0 × 0 = 0).
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 x = "foo", where , "foo" is a string literal with value foo. Methods such as escape sequences can be used to avoid the ...
A vertical slice doesn't necessarily affect every component in the software. For example, if the solution contains a web service, it would live in the same "floor" as the UI, and a feature like "supporting login/logout in webservice" that involves only the web service does not require a change in the UI, but the business and database access layers.
