There has been a continual debate on which programming language/s to learn, to use. As the latest TIOBE Programming Community Index for August 2021 indicates – C (13%), Python (12%), C++ (7%), Java (10%), and C#(5%) together control nearly half the programming activities worldwide. Further, C Programming Language Family (C, C++, C#, Objective C etc.) dominate more than 25% of activities. Hence, learning C++ is important as one learns about the entire family, about Object-Oriented Programming and gets a solid foundation to also migrate to Java and Python as needed. C++ is the mother of most general purpose of languages. It is multi-paradigm encompassing procedural, object-oriented, generic, and even functional programming. C++ has primarily been the systems language till C++03 which punches efficiency of the code with the efficacy of OOP. Then, why should I learn it if my primary focus is on applications? This is where the recent updates of C++, namely, C++11 and several later offer excellent depths and flexibility for C++ that no language can match. These extensions attempt to alleviate some of the long-standing shortcomings for C++ including porous resource management, error-prone pointer handling, expression semantics, and better readability. The present course builds up on the knowledge of C programming and basic data structure (array, list, stack, queue etc.) to create a strong familiarity with C++98 / C++03. Besides the constructs, syntax and semantics of C++ (over C), we also focus on various idioms of C++ and attempt to go to depth with every C++ feature justifying and illustrating them with several examples and assignment problems. On the way, we illustrate various OOP concepts. The course also covers important advances in C++11 and later released features..

Programming Assignment Q1 :

Complete the program with the following instructions.
• Fill in the blank at LINE-1 with appropriate keyword,
• Fill in the blanks at LINE-2 to declare fun() as a pure virtual function,
• fill in the blank at LINE-3 with approriate object instantiation,
The program must satisfy the given test cases

				
					#include<iostream>
using namespace std;

class Base{
protected:
    int s;

    public:
        Base(int i=0) : s(i){}

        virtual ~Base(){ }     //LINE-1

        virtual int fun() = 0; //LINE-2
};

class Derived : public Base{
    int x;
    public:
        Derived(int i, int j) : Base(i), x(j) {}
        ~Derived();
        int fun(){
            return s*x;
        }
};
class Wrapper{
    public:
        void fun(int a, int b){
            Base *t = new Derived(a, b); //LINE-3
            int i = t->fun();
            cout << i << " ";
            delete t;
        }
};

Derived::~Derived(){ cout << int(s/x) << " "; }
int main(){
    int i, j;

Programming Assignment Q2 :

Consider the following program with the following instructions.
Fill in the blank at LINE-1 and LINE-2 with appropriate return statements
The program must satisfy the sample input and output.

				
					#include <iostream>
using namespace std;
const double ir = 7;
const double bonus = 4;
class FD{
    protected:
        double principal;
    public:
        FD(double _p = 0.0) : principal(_p){}
        double getInterest(){ return principal * ir / 100; }
        double getExtraAmt(){ return principal * bonus / 100 ; }
        virtual double getMaturity() = 0;
};
class Customer : public FD{
    public:
        Customer(double _amt) : FD(_amt){}
        double getMaturity();
};
class Employee : public FD{
    public:
        Employee(double _amt) : FD(_amt){}
        double getMaturity();
};

double Customer::getMaturity(){

    return principal + getInterest(); //LINE-1
}


double Employee::getMaturity(){

    return principal + getInterest() + getExtraAmt(); //LINE-2
}

int main(){
    double d;
    cin >> d;
    FD *ep[2] = {new Customer(d), new Employee(d)};
    cout << ep[0]->getMaturity() << " ";
    cout << ep[1]->getMaturity();
    return 0;
}
