Design a class to overload a function num_calc() as follows  void num_calc(int num,char ch ) with one integer argument and one character argument, computes the cube of integer argument if choice ch is ‘c’/ ‘C’ otherwise finds its square.  void num_calc(int a,int b,char ch) with two integer arguments and one character argument.It computes the product of integer arguments if ch is’p’ else adds the integers void num_calc(String s1,String s2) with two string arguments,which prints whether the strings are equal or not
