Can't create an array of objects

[Alwayslearning337]

Hello, i was wondering if anyone was interested in helping me with my problem.The assignment is to create an array of objects from class called Objects.This is how the code that i have looks like:

(The classes are in its separate header file and i know i am supposed to include #include"nameofthefile.h" in all the files so i could use them properly)

class Object{
public:

string name;
double price;
Object();
Object(string name, double price);

};

class Store{

public:

Object* obj;
string address;
int nmrobject=0;

Store(string adr){
address=adr;
obj=new Object[10];
}


void addObject(Object o)
{
obj[nmrobject++] = o;//I don' know what to put in this function, and the

//assignment says i am not allowed to change nothing

//but how the class Store is written.I also need to

//print them out after they are created

}
void printOutObjects(){

}
};


int main(){
Store d("Some address");
d.addObject(Object("bread", 7));
d.addObject(Object("milk", 6.5));
d.addObject(Object("soup", 3.25));
d.printOutObjects();();

return 0;
}

This is my first post on this forum, so thanks to everyone who can helpme on this even a little bit.

void printOutObjects(){
    for(int i = 0; i < nmrobjects; ++i) {
        std:cout << obj[i].name << ' ' << obj[i].price << std::endl;
    }
}

Did you want something like that?

Output:

bread 7
milk 6.5
soup 3.25

Well, yeah something like that, but the main problem i am having is that i can't even create the objects that i am supposed to print out.

Still, thanks for a quick response. :D

Wait. Did it give you an compile error? If so, post it here.
Also in line: d.printOutObjects();();

Did you specify constructors of Object?

This is the build message that i get when trying to run the program:

obj\Debug\main.o||In function `main':|
main.cpp|14|undefined reference to `Object::Object(std::string, double)'|
main.cpp|15|undefined reference to `Object::Object(std::string, double)'|

You need to specify your object constructors.
Change declared constructors in Object declaration to:

Object(): name(0), price(0) {};
Object(std::string _name, double _price):name(_name), price(_price) {};

[Alwayslearning337]

That is good suggestion but as i said previously i am not allowed to change nothing but the class Store.Everything else needs to stay like it is.
Again, thanks for a quick response.

Ok, dont change class, write this after class:

Object::Object() {};
Object::Object(std::string _name, double _price):name(_name), price(_price) {};

You must specify those constructors, either in class, or outside it.

Thanks so much for your help, it did the trick.You just saved me a lot of trouble trying to find the problem.I am just starting to learn object oriented programming and it is nice to know that there is someone who will help you if you just ask.

One more time , thank you.
