I'm trying to reference an object in a function and it is giving me an "Object is inaccessible" error. Here is the header and cpp file in question.
customer header file below. I've put the object declaration at the bottom.
#pragma once
#include "bankAccount.h"
#include "checkingAccount.h"
#include "savingsAccount.h"
#include "address.h"
using namespace std;
class customer {
public:
customer(void);
customer(string,string);
~customer(void);
void setName(string n);
string getName();
void withdrawChecking(double);
void wihdrawSavings(double);
double depositSavings(double);
string print();
private:
string name
checkingAccount myChecking;
savingsAccount mySavings;
};
Here is the cpp file. I've bolded the problem statement.
#include "customer.h"
#include "checkingAccount.h"
customer::customer(void){
}
customer::customer(string n, string ac){
name = n;
mySavings.setAccount(ac);
myChecking.setAccount(ac);
}
void customer::setName(string n){
name = n;
}
string customer::getName(){
return name;
}
void withdrawChecking(double w){
myChecking.withdrawChecking(w);
}
So what is wrong with this last statement and my header?
Sorry for bad styling... first time posting a question.
You're missing a customer on the front of withdrawChecking. It should be:
void customer::withdrawChecking(double w)

So I am using Visual Studio to make a simple program for intro to Object Oriented Programming. I am using C++ language to do this, in Netbeans with JAVA OPP isn't so complicated but I am having trouble here. I have to make a simple Object, I chose to make my object called Movie. I made a Movie.h and Movie.cpp file. I included .h's extensions to my Movie.cpp and main.cpp but when I create the object in my main or try to i keep getting errors and underlines because my .cpp file is not recognizing my variables declared in .h, it keeps saying the variable is undefined.
So visual studio's wants to help me out and I followed their method so in my .h files they said they will define my methods for me, meaning they will set it up for me and when I clicked it i get this format
string Movie::getName()
{
return string();
}
While I am using this format for this function
string getName(){
return name;
}
My variables keeps getting red underlined saying they are undefined.
My Movie.h file
#pragma once
//Header File is where all of your class defenitions will go.
class Movie
{
private:
string name;
int length;
double rating;
public:
//Constructors
//A Default constructor
Movie();
//A Constructor that takes in 3 values, an int, a double and a string
Movie(int x, double y, string z );
//Get fucntions
//Get fucntions will get the required values.
string getName();
int getLength();
double getRating();
//Set functions
//Set fucntions will set the variables to the input values.
void setName(string x);
void setLength(int y);
void setRating(double z);
//toString Function
//A toString function that will display the details of the object
void toString();
};
My Movie.cpp File
#include "Movie.h"
#include "pch.h"
#include <iostream>
#include <string>
using namespace std;
//Default Construtor
Movie::Movie()
{
}
//A Construtor that takes in 3 values, int for length, double for rating, string for name
Movie::Movie(int x, double y, string z)
{
setLength(x);
setRating(y);
setName(z);
}
//Set functions
void setLength(int x) {
length = x;
}
void setRating(double y) {
rating = y;
}
void setName(string z) {
name = z;
}
//Get functions
int getLength() {
return length;
}
double getRating() {
return rating;
}
string getName() {
return name;
}
My .main
#include "pch.h"

using namespace std;
int main()
{
Movie mo1();
mo1.setName("Inceptio");
mo1.setLength(123);
cin.ignore(1);
return 0;
}
Now I havent worked on my toString method yet but I can't because I cant figure out what the real problem is, why is my .cpp not recognizing my variables? Is my format wrong? Is the visual studio's format right because I ran with their format and got bunch of errors as well or am I declaring them wrong or something? Thank you!

I'm creating a student data management console application for a project. I created a class called Student which is storing all the data that a student needs to have, and it also has all the getters and setters associated with it. Here is how all my files are laid out:
Student.h
#include <iostream>
#include <string>
using namespace std;
class Student {
private:
string name;
string id;
string email;
int presentation;
int essay1;
int essay2;
int project;
public:
//constructor
//Student();
//setters
void set_name(string);
void set_id(string);
void set_email(string);
void set_presentation(int);
void set_essay1(int);
void set_essay2(int);
void set_project(int);
//getters
string get_name();
string get_id();
string get_email();
int get_presentation();
int get_essay1();
int get_essay2();
int get_project();
};
Student.cpp
#include <iostream>
#include <string>
#include "Student.h"
using namespace std;
//constructor definition
/*
Student::Student(void) {
cout << "Student created" << endl;
}
*/
//setter definition
void Student::set_name(string s) {
name = s;
}
void Student::set_id(string s) {
id = s;
}
void Student::set_email(string s) {
email = s;
}
void Student::set_presentation(int a) {
presentation = a;
}
void Student::set_essay1(int a) {
essay1 = a;
}
void Student::set_essay2(int a) {
essay2 = a;
}
void Student::set_project(int a) {
project = a;
}
//getter definition
string Student::get_name() {
return name;
}
string Student::get_id() {
return id;
}
string Student::get_email() {
return email;
}
int Student::get_presentation() {
return presentation;
}
int Student::get_essay1() {
return essay1;
}
int Student::get_essay2() {
return essay2;
}
int Student::get_project() {
return project;
}
Main.cpp
#include <iostream>
#include <string>
#include "Student.h"
using namespace std;
int main() {
cout << "Hello World!" << endl;
Student student1;
Student student2;
Student student3;
student1.set_name("John");
student2.set_name("Bob");
student3.set_name("Carl");
return 0;
}
When I try to run my program, I get, amongst others, the following errors:
Error 1 error C2011: 'Student' : 'class' type redefinition
Error 2 error C2079: 'student1' uses undefined class 'Student'
Error 5 error C2228: left of '.set_name' must have class/struct/union
Error 9 error C2027: use of undefined type 'Student'
How can I go about fixing this issue?
I'm quite sure this is an error caused by the fact that student.h is included twice in a certain .cpp file. Thus you need to use so-called header guards to make sure the file is only included once in every .cpp file:
#ifndef STUDENT_H
#define STUDENT_H
#include <iostream>
#include <string>
using namespace std;
class Student {
/* ... */
};
#endif
The idea behind this is that an #include is a preprocessor directive that results in the argument file being copied into the file where the #include was issued. Hence, if files A and B include Student.h, and file C includes both files A and B, then the declaration of class Student is going to end up duplicated. Hence the error. The above macros make sure that this doesn't happen.
Edit as per the question author's comment:
#pragma once is the same as #ifndef .. #define #endif but non-standard .
See #pragma once vs include guards? for reference.
I had the same error. I just clean and rebuild the solution and error resolved.
I'm still a noobie in c++ so I am not to skilled in debugging yet. Just trying to figure out how to fix this compilation error.
CruiseShip.cpp:11: error: expected ‘)’ before ‘n’

You have 3 errors:
1 and 2. You don't declare print and CruiseShip (The constructor) as part of the class CruiseShip when you define them. You need to:
CruiseShip::CruiseShip(string n, string y, int p) : Ship(n,y) {
virtual void CruiseShip::print() {
3, you dont have a namespace Ship so this is unnecessary:
Ship::Ship s; // This only needs to be Ship s <- NameSpace::ObjectType nameOfObject;
After this it will compile http://ideone.com/wJ6mPO. It will not link however, because you have undefined references to all of the functions you have yet to define.
can sombody explain to me why my code will not work, and how to fix it thanks :)
I keep recieving this error :
no 'int burrito::setName()' member function declared in class 'burrito'
My goal is to call a function from a different class file
My main.cpp :
#include <iostream>
#include "burrito.h"
using namespace std;
int main()
{
burrito a;
a.setName("Ammar T.");
return 0;
}
My class header (burrito.h)
#ifndef BURRITO_H
#define BURRITO_H
class burrito
{
public:
burrito();
};
#endif // BURRITO_H
My class file (burrito.cpp):
#include "burrito.h"
#include <iostream>
using namespace std;
burrito::setName()
{
public:
void setName(string x){
name = x;
};
burrito::getName(){
string getName(){
return name;
};
}
burrito::variables(string name){
string name;
};
private:
string name;
};
Your code is a mess. You need to write function prototypes in the header file and function definitions in the cpp file. You are missing some basic coding structures. See below and learn this pattern of coding:
This code should work and enjoy burritos !
main():
#include <iostream>
#include "Header.h"
int main()
{
burrito a;
a.setName("Ammar T.");
std::cout << a.getName() << "\n";
getchar();
return 0;
}
CPP file:
#include "Header.h"
#include <string>
void burrito::setName(std::string x) { this->name = x; }
std::string burrito::getName() { return this->name; }
Header file:
#include <string>
class burrito
{
private:
std::string name;
public:
void setName(std::string);
std::string getName();
//variables(string name) {string name;} // What do you mean by this??
};
Your poor little burrito is confused. Confused burritos can't help much.
You may want your burrito declaration as:
class Burrito
{
public:
Burrito();
void set_name(const std::string& new_name);
std::string get_name() const;
private:
std::string name;
};
The methods could be defined in the source file as:
void
Burrito::set_name(const std::string& new_name)
{
name = new_name;
}
std::string
Burrito::get_name() const
{
return name;
}
The header file only has a constructor for the class. The member functions
setName(string) and getName()
are not declared in the header file and that is why you get the error.
Also, you need to specify the return type for functions.
One way to do this would be
//Header
//burrito.h
class burrito{
private:
string burrito_name;
public:
burrito();
string getName();
void setName(string);
}
//burrito.cpp
#include "burrito.h"
#include <iostream>
using namespace std;
string burrito::getName()
{
return burrito_name;
}
void burrito::setName(string bname)
{
bname =burrito_name;
}
This is a simple example for class in C++,
Save this in burrito.cpp file then compile and run it:
#include <iostream>
#include <string>
using namespace std;
class burrito {
public:
void setName(string s);
string getName();
private:
string name;
};
void burrito::setName(string s) {
name = s;
}
string burrito::getName() {
return name;
}
int main() {
burrito a;
a.setName("Ammar T.");
std::cout << a.getName() << "\n";
return 0;
}
So, I tried to make this code :
#include <iostream>
using namespace std;
class BuckysClass{
public:
void setName(string x){
name = x;
}
string getName(){
return name;
}
private:
string name;
};
int main()
{
BuckysClass bo;
bo.setName("Buckingham Palace");
cout << bo.getName();
return 0;
}
BECOMING TO A SEPARATED CLASS like this :
#include "BuckysClass.h"
#include <iostream>
#include <string>
using namespace std;
int main (){
BuckysClass bo;
bo.setName("Buckingham Palace");
cout << bo.getName();
return 0;
}
==============
#ifndef BUCKYSCLASS_H
#define BUCKYSCLASS_H
class BuckysClass
{
public:
void setName(string x);
string getName();
private:
string name;
};
#endif // BUCKYSCLASS_H
=============
#include "BuckysClass.h"
#include <iostream>
#include <string>
using namespace std;
BuckysClass::BuckysClass()
{
}
void setName(string x){
name = x;
}
string getName(){
return name;
}
When I run the first code, I succeed,
but I got error when running the separated class code,
help me find out what's wrong ???
I tried to use different code,
but it seems I can't find the reason,
the closest reason I believe, is the main doesnt call the function on the separated class properly.
If you write this code:
void setName(string x){
name = x;
}
string getName(){
return name;
}
The compiler interprete it as two functions called setName and getName, it has no idea they are member functions of your BuckysClass class.
You have to precise it with the following syntax:
void BuckysClass::setName(string x){
name = x;
}
string BuckysClass::getName(){
return name;
}
Additionally, here you are defining a default constructor:
BuckysClass::BuckysClass()
{
}
But you didn't put it in the class prototype. You have to add it somewhere in the class prototype definition in your .h file, or your compiler won't recognize it:
class BuckysClass
{
public:
BuckysClass(); // Default constructor.
void setName(string x);
string getName();
private:
string name;
};
