4th sem OOPC Write the following programs using OPERATOR OVERLOADING in CPP language.

1.      Write a program to enter two integers, two float number, two double numbers and find and display the greater of them using function overloading technique.


#include<iostream>
#include<conio.h>
using namespace std;
class over{
    public:
    int get(int,int);
    float get(float,float);
    double get(double,double);
};
int over::get(int a,int b){
        if(a>b){
            return a;
        }else{
            return b;
        }
}

float over::get(float a,float b){
        if(a>b){
            return a;
        }else{
            return b;
        }
}
double over::get(double a,double b){
    if(a>b){
        return a;
    }else{
        return b;
    }
}
int main(){
    int n1,n2,t;
    float x,y;
    double p,q;
    over obj;
    //clrscr();
    cout<<"\nEnter two integer number: "<<endl;
    cin>>n1>>n2;
    t=obj.get(n1,n2);
    cout<<"Maximum number is: "<<t;
    cout<<"\nEnter two float number: "<<endl;
    cin>>x>>y;
    float temp=obj.get(x,y);
    cout<<"Maximum number is: "<<temp;
    cout<<"\nEnter two double value"<<endl;
    cin>>p>>q;
    double pq = obj.get(p,q);
    cout<<"Maximum number is: "<<pq;

    return 0;
}

2.      Write a program that uses area () function for calculation area of triangle or a rectangle or a square using function overloading technique (without the use of classes).

#include<iostream>
#include<conio.h>
using namespace std;
float area(float a,float b){
    float an;
     /*for arera of triangle*/
    an = (a*b)/2;
    return an;
}
int area(int a){
    int an1;  /*For area of the square*/
    an1=a*a;
    return an1;
}
int area(int a,int b){
    int an2;
    /*For area of rectangle*/
    an2 = a*b;
    return an2;
}
int main(){
    int v,w,x;
    float y,z;
    cout<<"Enter the value two value for triangle : "<<endl;
    cin>>y>>z;
    cout<<area(y,z)<<endl;
    cout<<"Enter the value value for square : "<<endl;
    cin>>v;
    cout<<area(v)<<endl;
    cout<<"Enter the value two value for rectangle : "<<endl;
    cin>>w>>x;
    cout<<area(w,x)<<endl;
   return 0;
}

3.      Write a program to demonstrate the operation of operator overloading function.

#include<iostream>
#include<conio.h>
using namespace std;
class over{
    int a,b;
public:
    over(){
        a=5;
        b=3;
    }
    int putdata(void){
        cout<<"\nA= "<<a<<"\nB= "<<b<<endl;
    }
    int operator+(){
        int t;
        t=a+b;
        return t;
    }
};
int main(){
    over k;
    cout<<"Before operator overloadding.."<<endl;
    k.putdata();
    int p = +k;
    cout<<"total of a+b= "<<p;
}

}
