The end-loop marker specifies the name of the index variable, which must correspond to the name of the index variable at the start of the for-loop. Some languages (PL/I, Fortran 95, and later) allow a statement label at the start of a for-loop that can be matched by the compiler against the same text on the corresponding end-loop statement.
Unlike other for loop constructs, however, foreach loops [1] usually maintain no explicit counter: they essentially say "do this to everything in this set", rather than "do this x times". This avoids potential off-by-one errors and makes code simpler to read.
In Unicode, a Private Use Area (PUA) is a range of code points that, by definition, will not be assigned characters by the standard. [1] Three private use areas are defined: one in the Basic Multilingual Plane (U+E000–U+F8FF), and one each in, and nearly covering, planes 15 and 16 (U+F0000–U+FFFFD, U+100000–U+10FFFD).
For example, there was a proposal in 1999 to add C++-like const to the language, which was possible using the const word, since it was reserved but currently unused; however, this proposal was rejected – notably because even though adding the feature would not break any existing programs, using it in the standard library (notably in ...
For example, the contiguous range of 32 noncharacter code points U+FDD0..U+FDEF share none of the properties common to the other characters in the Arabic Presentation Forms-A block, that they are certainly not Arabic script characters or "right-to-left noncharacters", and are assigned there as a filler to this block given that it has been ...
508 Loop Detected (WebDAV; RFC 5842) The server detected an infinite loop while processing the request (sent instead of 208 Already Reported). 510 Not Extended (RFC 2774) Further extensions to the request are required for the server to fulfil it. [28] 511 Network Authentication Required (RFC 6585) The client needs to authenticate to gain ...
Devanagari is a Unicode block containing characters for writing languages such as Hindi, Marathi, Bodo, Maithili, Sindhi, Nepali, and Sanskrit, among others.In its original incarnation, the code points U+0900..U+0954 were a direct copy of the characters A0-F4 from the 1988 ISCII standard.
Iota ⍳3 by itself would produce {1 2 3}. The diaeresis ¨ or mini double-dot means repeat or over each or perform each separately so iota repeats (in human i.e., reversed terms, the APL interpreter reads 3 3 over each use iota), concisely: iota for each 3.
