Answer / binoy

Write a C++ program to create a class called COMPLEX and
implement the following overloading functions ADD that
return a COMPLEX number .
I. ADD(a,s2) - where a is an integer(real part) and s2 is a
complex number.
II. ADD(s1,s2) - where s1 and s2 are complex objects.


#include<iostream.h>
#include<conio.h>
class complex
{
int r,i;
public:
void read();
void print();
friend complex add(int a,complex c);
friend complex add(complex c1,complex c2);
};
void complex::read()
{
cout<<"Enter real and imaginary\n";
cin>>r>>i;
}
void complex::print()
{
cout<<r<<"+i"<<i<<endl;
}
complex add(int a,complex c)
{
complex t;
t.r=a+c.r;
t.i=c.i;
return t;
}
complex add(complex c1,complex c2)
{
complex t;
t.r=c1.r+c2.r;
t.i=c1.i+c2.i;
return t;

}
void main()
{
int a=2;
clrscr();
complex s1,s2,s3;
s1.read();
cout<<"\ns1 : ";
s1.print();
s2=add(a,s1);
cout<<"s2 : 2+s1\n";
cout<<" : ";

For the FIFA world cup, Paul the octopus has been predicting the winner of each match with amazing success. It is rumored that in a match between 2 teams A and B, Paul picks A with the same probability as A’s chances of winning. Let’s assume such rumors to be true and that in a match between Ghana and Bolivia, Ghana the stronger team has a probability of 2/3 of winning the game. What is the probability that Paul will correctly pick the winner of the Ghana-Bolivia game?
