Q5: Continue with Point class:
a) Copy the previous program to a new file.
b) Overload [] operator, index 0 return x, index 1 return y of Point Object. (Only index
0,1 is valid, else terminate program)
Implement prefix and postfix operator overload for Point object, ++ operator should
increase x and y of Point by 1s.
c) Overload the prefix and postfix ++ operators.
Use following main() to test your class.
int main(){
Point a(3,4);
cout<<a[0]<<endl; // 3
cout<<a[1]<<endl; // 4
a[0]=1;
a[1]=2;
cout<<a<<endl; // (1,2)
cout<<++a<<endl;
// (2,3)
cout<<a<<endl; // (2,3)
cout<<a++<<endl;
// (2,3)
cout<<a<<endl;
}
Output from given main:
3
4
(1,2)
(2,3)
(2,3)
(2,3)
(3,4)
// (3,4)
