Question
could you pls help mi,i realli need your help.i am trying to do a simple addition.i'm nt sure whether i'm doing it the right way,could u pls guide mi.i will be so appericated for all the help frm u.
suppose vector X is (a1, b1, c1) and Y is (a2, b2, c2).
Addition:X + Y = (a1+a2, b1+b2, c1+c2).

code:
class myVector
{

public:
int x,y,z;
myVector operator+(const myVector &mv)const;

};

myVector myVector::operator +(const myVector &mv)const  //Addition
{
myVector mv;
mv.x = x + mv.x;
mv.y = y + mv.y;
mv.z = z + mv.z;
return mv;
}

//main program to test the class.
int main()
{

myVector A,B,C;

cout << "Enter first vector, format (a,b,c): ";
cin >> A;

cout << "Enter second vector, format (a,b,c): ";
cin >> B;

C = A + B;
cout<<"Addition A+B = "<< C << endl;

return 0;
}

Hi dear Liza !

Ive made some simple changes with your code , and now its working fine , kindly go through the changes and understand the usage of const and how to access members in a class using objects

here s the code

#include<iostream>
using namespace std;
class myVector
{

public:
int x,y,z;
myVector operator+( myVector &mv);

};

{
mv.x = x + mv.x;
mv.y = y + mv.y;
mv.z = z + mv.z;
return mv;
}

//main program to test the class.
int main()
{

myVector A,B,C;

cout << "Enter first vector, format (a,b,c): ";
cin >> A.x >>A.y>>A.z;

cout << "Enter second vector, format (a,b,c): ";
cin >> B.x>>B.y >>B.z;

C = A + B;
cout<<"Addition A+B = "<< C.x <<" "<< C.y <<" "<< C.z <<" ";
cin.get();
return 0;

}

Note: Ive tested this code and found working in VS2008 if you encounter any issues please lemme know
