This is a list of operators in the C and C++ programming languages.. All listed operators are in C++ and lacking indication otherwise, in C as well. Some tables include a "In C" column that indicates whether an operator is also in C. Note that C does not support operator overloading.
C++20 is a version of the ISO/IEC 14882 standard for the C++ programming language. C++20 replaced the prior version of the C++ standard, called C++17 , and was later replaced by C++23 . [ 1 ] The standard was technically finalized [ 2 ] by WG21 at the meeting in Prague in February 2020, [ 3 ] had its final draft version announced in March 2020 ...
The three-way comparison operator or "spaceship operator" for numbers is denoted as <=> in Perl, Ruby, Apache Groovy, PHP, Eclipse Ceylon, and C++, and is called the spaceship operator. [2] In C++, the C++20 revision adds the spaceship operator <=>, which returns a value that encodes whether the 2 values are equal, less, greater, or unordered ...
PHP supports standard C/C++ style comments, but supports Perl style as well. Python The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [ 19 ]
C++11 extended this further, to make classes act identically to POD objects in many more cases. ^c pair only ^d Although Perl doesn't have records, because Perl's type system allows different data types to be in an array, "hashes" (associative arrays) that don't have a variable index would effectively be the same as records.

[4] [5] Some compilers, such as Microsoft Visual C++ have, at least in the past, required the header to be included in order to use these identifiers unless a compiler flag is set. [6] [7] The header <ciso646> was deprecated in C++17, and removed in C++20, [8] while <iso646.h> was retained for compatibility with C. [9]
