An absent referent is, in semantics, a sign of a non-existent referent - nothing, null, vacuum, void.

The Semantics ended in 1996.
Journal of Semantics was created in 1982.
Some people dont know the sentence for semantics.
Semantics refer to the meaning of words and how they are interpreted within a particular context or language.
Journal of Web Semantics was created in 2003.
Natural Language Semantics was created in 1993.
semantics = words; syntax = how they're used
Semantics is how we say something. Pragmatics is how we do something.
The only way to swap two values using call by value semantics is to pass pointer variables by value. A pointer is a variable that stores an address. Passing a pointer by value copies the address, the value of the pointer, not the pointer itself. By passing the addresses of the two values to be swapped, you are effectively passing those values by reference. Both C and C++ use pass by value semantics by default, however C++ also has a reference data type to support native pass by reference semantics. By contrast, Java uses pass by reference semantics by default. In C, to swap two variables using pass by value: void swap (int* p, int* q) { int t = *p; *p = *q; *q = t; } In C++, to swap two variables using pass by reference: void swap (int& p, int& q) { std::swap (p, q); } Note that C++ is more efficient because std::swap uses move semantics; there is no temporary variable required to move variables. With copy semantics, a temporary is required. However, with primitive data types, there is a way to swap values without using a temporary, using a chain of exclusive-or assignments: void swap (int* p, int* q) { *p^=*q^=*p^=*q; }
