Template Pointer Type....

[Nadeem Afroz]

Hello Folks...

Just going through the templates... found one good question worth sharing

C++ allows the syntax type

template <class T>
T * ptr;

can this ptr be used to point to types likes int variable or float variable

ex: int i =10;
ptr = &i;

If this can be done plz share the syntax of doing it...
Comments will be appreciated...

Hi,

I'm not quite sure what you're looking for here...but anyways...
The *ptr can point out T-objects, the T object can be an int, float or Whatever just as long as you specify it when you use the template.

i have created
template <class T>
T * ptr;

main()
{
int i =10;
//Here i want to assign the address of i to ptr & display value using ptr

float j = 20.23;
//here i want to assing the address of j to ptr & display value using ptr

return 0;
}

Hi,

I hope I understood your question correctly. What you're trying to do is declare a template<class> , och then point it out with a template<class> pointer.

Is that correct?

Hi,

Not quite sure I'm afraid...I think you have to override some operator, don't quite remember...sorr y.

C++ allows the syntax type

template <class T>
T * ptr;

NO... It doesn't. This is not a valid template definition. Are you trying to do this:

template<typename T>
class MyClass
{
 T* m_Ptr;
};

If so, the syntax would be:

float i = 10;
MyClass<float>* c;
c.m_Ptr = &i;
