Static block usage

[pandu19]

Hello

I'm beginner in cpp programming. I'm confused about static block usage in cpp code
so should any one explain about usage of static block.




Thanks & Regards

Static block? Do you mean static variables or static functions?

static int x; // global variable is visible only in this translation unit

static void f() // global function is visible only in this translation unit
{
}

void g()
{
    static int a; // behaves like a global visible only in this function
}

class Tmp
{
    static int b; // all objects of type Tmp will see the same b

public:

    static void sf() // function can be used without an instantiation
    {
    }
};

int Tmp::b; // b must be defined externally
