Most of the operators available in C and C++ are also available in other C-family languages such as C#, D, Java, Perl, and PHP with the same precedence, associativity, and semantics. Many operators specified by a sequence of symbols are commonly referred to by a name that consists of the name of each symbol.
However, do note that a shift operand value which is either a negative number or is greater than or equal to the total number of bits in this value results in undefined behavior. This is defined in the standard at ISO 9899:2011 6.5.7 Bit-wise shift operators. For example, when shifting a 32 bit unsigned integer, a shift amount of 32 or higher ...
two objects being equal but distinct, e.g., two $10 banknotes; two objects being equal but having different representation, e.g., a $1 bill and a $1 coin; two different references to the same object, e.g., two nicknames for the same person; In many modern programming languages, objects and data structures are accessed through references. In ...
It is often attached to a technical term to indicate that the exclusive meaning of the term is to be understood. The opposite is non-strict, which is often understood to be the case but can be put explicitly for clarity. In some contexts, the word "proper" can also be used as a mathematical synonym for "strict".
The result of shifting by a bit count greater than or equal to the word's size is undefined behavior in C and C++. [2] [3] Right-shifting a negative value is implementation-defined and not recommended by good coding practice; [4] the result of left-shifting a signed value is undefined if the result cannot be represented in the result type. [2]
The relation not greater than can also be represented by , the symbol for "greater than" bisected by a slash, "not". The same is true for not less than, . The notation a ≠ b means that a is not equal to b; this inequation sometimes is considered a form of strict inequality. [4] It does not say that one is greater than the other; it does not ...
In BASIC, Lisp-family languages, Lua and C-family languages (including Java and C++) the operator >= means "greater than or equal to". In Sinclair BASIC it is encoded as a single-byte code point token. In Fortran, the operator .GE. means "greater than or equal to". In Bourne shell and Windows PowerShell, the operator -ge means "greater than or ...
The real numbers are more numerous than the natural numbers. Moreover, R {\displaystyle \mathbb {R} } has the same number of elements as the power set of N {\displaystyle \mathbb {N} } . Symbolically, if the cardinality of N {\displaystyle \mathbb {N} } is denoted as ℵ 0 {\displaystyle \aleph _{0}} , the cardinality of the continuum is
