Learn about local static variables in C language, their definition, usage, and examples to understand how they differ from regular local variables.
(1) a static local variable defines its lifetime in the function as the entire source, but its scope remains the same as that of the automatic variable, and can only be used within the function defining the variable. After exiting the function, you cannot use it even though it still ...
initial begin //hierarchical reference to local variable $display("init2.n = %0d", init2.n); end endmodule module next; //Static variable 'n' is visible in the module 'next' initial begin $display("Statically declared 'n' in module 'next' = %0d",$unit::n); end endmodule Simulati...
Each instantiation of function template has its own copy of local static variables. For example, in the following program there are two instances: void fun(int ) and void fun(double ). So two copies of static variable i exist. 1 #include <iostream> 2 using namespace std; 3 4 template...
static local variable Putting the keywordstatic in front of a local variable declaration creates a special type of variable, a so-called static local variable. This variable keeps its value even after the method ends. The next time you call this method, the variable isn’t...
c extern int foo(); int globvar = foo(); int bar() { static int localvar = foo(); return localvar; } $ gcc localstatic.c -c localstatic.c:2: error: initializer element is not constant localstatic.c: In function ‘bar’: localstatic.c:5: error: initializer element is not ...
Generating a unique ID number is very easy to do with a static duration local variable: int generateID() { static int s_itemID{ 0 }; return s_itemID++; // makes copy of s_itemID, increments the real s_itemID, then returns the value in the copy } Copy The first time this funct...

Astaticclass is basically the same as a non-static class, but there's one difference: a static class can't be instantiated. In other words, you can't use thenewoperator to create a variable of the class type. Because there's no instance variable, you access the mem...
