calling a function from static function

Question

Hi,

how can i call a function which computes with input parameters from an another static function.

say,

class X
{
   static void xyz();

   static int pqr(int, int);
};

void X::xyz()
{
...pqr(10,20);

}

int X::pqr(int t1, int t2)
{

  return t1*t2;
}

Answer 1

You have to call instance methods off an instance of the class. Otherwise, just call it off the class.

X::pqr(10, 20)

Answer 2

Your question is very vague, but it looks like you just need to do something like this:

void X::xyz()
{
    int foo = X::pqr(10, 20);
}

int X::pqr(int t1, int t2)
{
    return t1*t2;
}

Answer 3

1) Call it just like pqr(10, 20);

2) You have an error in xyz() definition. It should be

void X::xyz()

Note: you don't need static keywords in the definition of the function, only in the declaration.

Answer 4

Change the following line:

static X::void xyz()

to this:

void X::xyz()
