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;
}

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.

You have to call instance methods off an instance of the class. Otherwise, just call it off the class.
X::pqr(10, 20)

The qualification is not even needed if you are calling from within the class context (which includes the definition of other static class member functions)
Change the following line:
static X::void xyz()
to this:
void X::xyz()

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;
}

The class qualification is not needed as
X::xyz is already within the class context.

@David: True - the class qualification is redundant but harmless - I guess it depends on your preferred coding style.
void X::xyz()instead ofX::void xyz()?
