#### Class Vector coderinme

write a class vector to represent an integer array v[N] (assume N=10).

Include (i) operator functions to overload input (>>) and output (<>v1; can be used to read N values in the array v[N] of

v1 vector object. Similarly, cout<<v1; can be used to output v[N] of object v1, (ii)

operator function to overload + operator that finds sum of two vector objects,

and (iii) other necessary member functions. Write a C++ program to use this

class reads data into two vector objects and finds their sum.

Solution:

```
#include<iostream.h>
#include<conio.h>
const int N=10;
class vector
{
int v[N];
public:
vector();
vector(int *x);
vector operator+(vector v1);
friend istream & operator>>(istream &din,vector &b);
friend ostream & operator<<(ostream &dout,vector &b);
};
vector::vector()
{
for(int i=0;i<N;i++)
v[i]=0;
}
vector::vector(int *x)
{
for(int i=0;i<N;i++)
v[i]=x[i];
}
istream & operator>>(istream &din,vector &b)
{
cout<<"enter 10 values in the Vector:"<<endl;
for(int i=0;i<N;i++)
{
din>>b.v[i];
}
return din;
}
ostream & operator<<(ostream &dout,vector &b)
{
for(int i=0;i<N;i++)
{
dout<<b.v[i]<<",";
}
return dout;
}
vector vector:: operator+(vector v1)
{
vector sum;
for(int i=0;i<N;i++)
{
sum.v[i]=v[i]+v1.v[i];
}
return sum;
}
int main()
{
vector v1,v2,v3;
cin>>v1;
cin>>v2;
v3=v1+v2;
cout<<endl<<"The two Vectors are"<<endl;
cout<<endl<<"v1:=["<<v1<<"]"<<endl;
cout<<endl<<"v2:=["<<v2<<"]"<<endl;
cout<<endl<<"Sum of two vectors are"<<endl;
cout<<endl<<"v3:=["<<v3<<"]"<<endl;
getch();
return 0;
}
```
