The define consists of a single token (one operand only, no operators), the parentheses are not needed because a single token (such as 100) is an indivisible atom when lexing and parsing. But I would recommend the following rules when it comes to macros:
Dec 9, 2010 · 345. A bracket - [ or ] - means that end of the range is inclusive -- it includes the element listed. A parenthesis - ( or ) - means that end is exclusive and doesn't contain the listed element. So for [first1, last1), the range starts with first1 (and includes it), but ends just before last1. Assuming integers:
Apr 17, 2009 · You can do something very close using a small C++ helper class. StartStopper() { start(); } ~StartStopper() { stop(); } Then in your code: StartStopper ss; // code here. When execution enters the block and constructs the ss variable, the start() function will be called. When execution leaves the block, the StartStopper destructor will be ...

The syntax is straightforward, following the same principles as property accessors. For example, in your case where an int is the key or index: public int this[int index] {. get => GetValue(index);
However, there are a lot of occurrences of array[2] and I was looking for a way to quick switch between the two. I was trying to use a preprocessor #define statement. #define array[2] array_0, array_1. int array[2]; //if define is included should become int array_0, array_1; However, this gives the following warnings/errors.
f-strings (python 3) You can avoid having to double the curly brackets by using f-strings ONLY for the parts of the string where you want the f-magic to apply, and use regular (dumb) strings for everything that is literal and might contain 'unsafe' special characters.
Apr 5, 2012 · the square brackets are the method name like Array#size you have Array#[] as a method and you can even use it like any other method: array = [ 'a', 'b', 'c'] array.[](0) #=> 'a'. array.[] 1 #=> 'b'. array[2] #=> 'c'. the last one is something like syntactic sugar and does exactly the same as the first one.
Nov 5, 2010 · A class definition is a bit different from a function/method definition. The parentheses in class definitions are for defining from which class you inherit. You don't write def in front of it, and when you inherit from 'object' which is the default you don't need the parentheses for the definition. So you can write either: class C(): Or: class C:
Mar 1, 2015 · Alternative to this would be. const int kSomeValue = 1234; For discussion about advantages of one or the other see #define vs const in Objective-C. As for brackets - in more complex cases they are necessary exactly because preprocessor makes copy-paste with #define. Consider this example: #define BIRTH_YEAR 1990.
