Beginers Coding Help Required

I need codign help

Problem :
*******************************
Consider an entity as Customer. Let its attributes be Name, Contact address and Phone no. A function is responsible for setting and another for printing the values for an instance of this entity. Implement this entity with its attributes and functions as a struct in C++.

#include <iostream>
using namespace std;

struct Customer
{
       char Name;
       char Address;
       double Phone;
};

int main()
{
         { cout << "Enter Name:" ; cin >> Name; }
         { cout << "Enter Address:" ; cin >> Address; }
         { cout << "Enter Phone Number" ; cin >> Phone; }
};

I need a help with above problem..

Is my above code correct ?

[tabstop]

It's correct, provided in your world no one has names or addresses longer than one letter and people have decimals in their phone numbers. Make them std::strings instead.

[Desolation]

You have way too many braces. You don't need any of those in your main() function except the first and last one. A single char is not enough to contain a name or an adress so I would make it a string instead.

hurray !!!!

#include <iostream>
using namespace std;

struct Customer
{
       string Name;
       string Address;
       double Phone;
};

int main()
{
         { 
         cout << "Enter Name:" ; cin >> Name;
         cout << "Enter Address:" ; cin >> Address;
         cout << "Enter Phone Number" ; cin >> Phone; }
};

How to implement as a class in C+ ?

How to implement as a class in C+ ?

You could read the Introduction to Classes for starters.

By the way, the name of the language is C++, not C+.

[kolucoms6]

Sorry but that was a Type Error :-)

Don't forget to #include <string>.

If that's your code, congratulations. Good work.

You haven't quite solved the problem yet, though. First, you can change it from a struct to a class by changing the word struct to class. However, you'll run into some other problems, since you are accessing those variables in main. I would wait until later for that, leave it as a struct for now.

The problem says to write functions that set and get those values. You are setting the values in main, but you need to do each separately in its own function.

Your next step is to write a simple function. You can try to write an empty function first and get it to compile, then add more later. So add a member function to your struct and see if you can get it right.

[kolucoms6]

When you say

"you need to do each separately in its own function."

Can you help me with oen samll Example please ?

[Daved]

Look at the processorspeed variable in the tutorial linked to by laserlight. There is a getspeed and setspeed function for it.

Your assignment says, "A function is responsible for setting and another for printing the values..." I don't know if that means you need a function for each variable, or if you need just one set and one print function. Either way, you'll need a member function like the ones in that example, so I'd start with one that sets the name and one that prints it.

Also, I mentioned you need to change your code to a class, but the assignment says tomake a struct, so that's not necessary.

Setter and getter functions - basic classes

class MyClass
{
public:
MyClass(); // constructor
// get functions
// set functions
private:
// variables to get and set
};

[kolucoms6]

class MyClass
{
public:
MyClass(); // constructor
// get functions
// set functions
private:
// variables to get and set
};

I guess above code is good for Class, not for Struct ?

[laserlight]

I guess above code is good for Class, not for Struct ?

You can use it for struct as well. The difference between the two lie mainly in the default access of members (struct: public; class: private).

>> I guess above code is good for Class, not for Struct ?

In that code you can change the word class to struct and it will be exactly the same. Don't worry about class or struct. Just use struct (since the assignment asks for struct), and the code that works for class should work for struct as well.
