Question

CISP 400 C++ Programming   

Please note, you are required to include the following when you use g++ to compile: -pedantic

           For example:

                                    g++ -pedantic filename.cpp

This will give a warning if you attempt to use any non-standard feature in g++. You must correct your code so that you do not receive any warnings of this type.

• Log on to the Linux server.
• Create four files:
  • Vector.h
  • Vector.cpp
  • VectorMain.cpp
  • Makefile
• In Vector.h:

//Student header here

#ifndef VECTOR_H_DEF   //DEF: These are my initials replace with yours

#define VECTOR_H_DEF //DEF: These are my initials replace with yours

#include <iostream>

#include <cmath> //if needed

using namespace std;

class Vector

{

double _x;

double _y;

double _z;

public:

Vector();

Vector(double X, double Y, double Z = 0.0);

void display() const; // <_x, _y, _z>

  void add(const Vector&);

void sub(const Vector&);

void mult(const double&);

void div(const double&);

void normalize();

double length()const;

};

#endif

In Vector.cpp, implement these member functions.

In VectorMain.cpp, write a test main to test your code.

Submit these four files via the drop-box

Definitions:

<x₁, y₁, z₁> + <x₂, y₂, z₂> = <x₁+x₂, y₁+y₂, z₁+z₂>

<x₁, y₁, z₁> - <x₂, y₂, z₂> = <x₁-x₂, y₁-y₂, z₁-z₂>

<x, y, z> * d = <x*d, y*d, z*d>

<x, y, z> / d = <x/d, y/d, z/d>

|<x, y, z>| = Sqrt(x² + y² + z²) |v|: the length of v

normalize(v) = v/|v|

Can someone help me with this? I made the files 4 files
