ABYSS

Yes, we can create an object of the Base class.If we make a class as abstract then we can't create an object of that class.we can create only pointer of that class this is because to provide one interface to access and so that runtime time polymorphism can implement.

What is the requirement of compile time overloading?

Mamta

• Sep 14th, 2017

Compile time overloading or static binding or early binding means to have same method name with different arguments. Example
sample(int a)
sample(int a, int b)
sample(char a)
sample(int a, char b)
sample(int a, char b, string c)

All of these are example of compile time overloading.

Actually?size of class having no variable but only 1 function is determined by the variables size declared in that fuction. So the size of the class will be the total size of variables which have been declared in that member function.

Sumit

Size would be one.because class doesnt have any data and a member function.what member function return it doesnt matter.and small unit is 1 in memory so it size will be 1.
