Answer to Question #193351 in C++ for Sivasurya

Question

The postage for ordinary post is Rs. 2.00 for the first 15 grams and Rs. 1.00 for each additional 10 grams. Write a C++ program to calculate the charge of postage for a post weighting N grams. Read the weights of N packets and display the total amount of postage using multiple inheritance.

* Base class-1: Member variables are name, source and destination.

* Base class-2: Member variables are no. of packets and weight.

* Derived class: Member functions display(), displays the name, source, destination, total weight and total amount.

Answer 1

#include<iostream>
#include<string>
using namespace std;

class Base_Class_1{
  public:
    std::string name;
    std::string source;
    std::string destination;
};

class Base_class_2{
  public:
    int no_of_pack=0;
    int weight=0;
};

class Derived_class: public Base_Class_1, public Base_class_2{
  public:
    int total_weight=0;
    int total_amount=0;
    void display(){
      total_weight=weight*no_of_pack;
      total_amount=2;
      if(total_weight>15)
          total_amount += (total_weight-15)*1;
      std::cout<<"name"<<name<<std::endl;
      std::cout<<"source"<<source<<std::endl;
      std::cout<<"destination"<<destination<<std::endl;
      std::cout<<"total weight"<<total_weight<<std::endl;
      std::cout<<"total amount"<<total_amount<<std::endl;
  }
};

int main(){
  Derived_class a;  //object of derived class
  a.name = "name test";
  a.destination = "destination test";
  a.source="source test";
  a.no_of_pack=20;
  a.weight=2;
  a.display();
  
  return 0;
