1) static member functions do not have this pointer.
For example following program fails in compilation with error “`this’ is unavailable for static member functions “
#include<iostream> class Test {
static Test * fun() {
return this ; // compiler error
}
}; int main()
{ getchar ();
return 0;
} |
2) A static member function cannot be virtual (See this G-Fact)
3) Member function declarations with the same name and the name parameter-type-list cannot be overloaded if any of them is a static member function declaration.
For example, following program fails in compilation with error “‘void Test::fun()’ and `static void Test::fun()’ cannot be overloaded “
#include<iostream> class Test {
static void fun() {}
void fun() {} // compiler error
}; int main()
{ getchar ();
return 0;
} |
4) A static member function can not be declared const, volatile, or const volatile.
For example, following program fails in compilation with error “static member function `static void Test::fun()’ cannot have `const’ method qualifier ”
#include<iostream> class Test {
static void fun() const { // compiler error
return ;
}
}; int main()
{ getchar ();
return 0;
} |
