Can we remove parentheses around arguments in C macros definitions?
Here’s a relatively dumb example, but it does have a different result: #define Streq(s1, s2) (strcmp((s1), (s2)) == 0) #define MyStreq(s1, s2) (strcmp(s1, s2) == 0) #define s1 “foo”, “blah” int main() { Streq(s1, “blah”); // Compiles and compares equal. MyStreq(s1, “blah”); // Compiler error. Too many parameters. }
List of all Unicode’s open/close brackets
There is a plain-text database of information about every Unicode character available from the Unicode Consortium; the format is described in Unicode Annex #44. The primary information is contained in UnicodeData.txt. Open and close punctuation characters are denoted with Ps (punctuation start) and Pe (punctuation end) in the General_Category field (the third field, delimited by … Read more
parsing nested parentheses in python, grab content by level
You don’t make it clear exactly what the specification of your function is, but this behaviour seems wrong to me: >>> ParseNestedParen(‘(a)(b)(c)’, 0) [‘a)(b)(c’] >>> nested_paren.ParseNestedParen(‘(a)(b)(c)’, 1) [‘b’] >>> nested_paren.ParseNestedParen(‘(a)(b)(c)’, 2) [”] Other comments on your code: Docstring says “generate”, but function returns a list, not a generator. Since only one string is ever returned, … Read more
Parenthesis/Brackets Matching using Stack algorithm
Your code has some confusion in its handling of the ‘{‘ and ‘}’ characters. It should be entirely parallel to how you handle ‘(‘ and ‘)’. This code, modified slightly from yours, seems to work properly: public static boolean isParenthesisMatch(String str) { if (str.charAt(0) == ‘{‘) return false; Stack<Character> stack = new Stack<Character>(); char c; … Read more
Remove Text Between Parentheses PHP
$string = “ABC (Test1)”; echo preg_replace(“/\([^)]+\)/”,””,$string); // ‘ABC ‘ preg_replace is a perl-based regular expression replace routine. What this script does is matches all occurrences of a opening parenthesis, followed by any number of characters not a closing parenthesis, and again followed by a closing parenthesis, and then deletes them: Regular expression breakdown: / – … Read more
What do the parentheses around a function name mean?
In the absence of any preprocessor stuff going on, foo‘s signature is equivalent to int foo (int *bar) The only context in which I’ve seen people putting seemingly unnecessary parentheses around function names is when there are both a function and a function-like macro with the same name, and the programmer wants to prevent macro … Read more
When do extra parentheses have an effect, other than on operator precedence?
TL;DR Extra parentheses change the meaning of a C++ program in the following contexts: preventing argument-dependent name lookup enabling the comma operator in list contexts ambiguity resolution of vexing parses deducing referenceness in decltype expressions preventing preprocessor macro errors Preventing argument-dependent name lookup As is detailed in Annex A of the Standard, a post-fix expression … Read more
Advanced JavaScript: Why is this function wrapped in parentheses? [duplicate]
There are a few things going on here. First is the immediately invoked function expression (IIFE) pattern: (function() { // Some code })(); This provides a way to execute some JavaScript code in its own scope. It’s usually used so that any variables created within the function won’t affect the global scope. You could use … Read more
PHP is confused when adding and concatenating
Both operators the addition + operator and the concatenation . operator have the same operator precedence, but since they are left associative they get evaluated like the following: echo ((“sum:” . $a) + $b); echo (“sum:” . ($a + $b)); So your first line does the concatenation first and ends up with: “sum: 1” + … Read more
