Outermost parentheses are dropped: M N instead of (M N). Applications are assumed to be left associative: M N P may be written instead of ((M N) P). [19] When all variables are single-letter, the space in applications may be omitted: MNP instead of M N P. [20] The body of an abstraction extends as far right as possible: λx.M N means λx.(M N ...
The body of the function starts on line 2 since it is indented one level (4 spaces) more than the previous line. The if clause body starts on line 3 since it is indented an additional level, and ends on line 4 since line 5 is indented a level less, a.k.a. outdented.
Code page 1021 (CCSID 1021), [1] also known as CP1021 or CH7DEC, [2] is an IBM code page number assigned to the Swiss variant of DEC's National Replacement Character Set (NRCS). [3] [4] [5] The 7-bit character set was introduced for DEC's computer terminal systems, starting with the VT200 series in 1983, but is also used by IBM for their DEC emulation.
Parentheses can be nested, and should be evaluated from the inside outward. For legibility, outer parentheses can be made larger than inner parentheses. Alternately, other grouping symbols, such as curly braces { } or square brackets [ ], are sometimes used along with parentheses ( ). For example:
Starting after the second symbol, match the shortest subexpression y of x that has balanced parentheses. If x is a formula, there is exactly one symbol left after this expression, this symbol is a closing parenthesis, and y itself is a formula. This idea can be used to generate a recursive descent parser for formulas. Example of parenthesis ...
The erase–remove idiom cannot be used for containers that return const_iterator (e.g.: set) [6] std::remove and/or std::remove_if do not maintain elements that are removed (unlike std::partition, std::stable_partition). Thus, erase–remove can only be used with containers holding elements with full value semantics without incurring resource ...
The most vexing parse is a counterintuitive form of syntactic ambiguity resolution in the C++ programming language. In certain situations, the C++ grammar cannot distinguish between the creation of an object parameter and specification of a function's type.
