B. #
Explanation:
Every preprocessing directive must begin with the # character.
For example:
#define : Used to define a macro
#ifndef : Conditional evaluation of macro
#include : Used to include other preprocessor header file as part of the code

//statement and function
};
main()
{
classname objectname;
}
implementation of class in c++
#include<iostream>
class test // class declaration
{
public: // access modifier
void fun3() // Method definition
{
cout<<" hello :";
}
};
void main() // main function
{
test ob;// creating object
ob.fun3(); // calling function
}
In this program we declared a class "test " in class test. We giving public access modifier .The public access modifier define that variable and function are accessible outside the class and in main method we create the object ob which call the function fun3().
