Mixing struct, pointer and array.
Hai,
I`m trying to use pointer, array and struct together. I`m a newbie.
Here is my code. I still don`t know what`s wrong with it. So guys plz help
me out.
#include <iostream>
using namespace std;
#include <conio.h>
const int nameSize = 20;
struct pizza
{
char name[nameSize];
float diameter;
float weight;
};
int main()
{
cout << "Welcome to William Wingate Pizza Analysis Service!
";
cout << "How many pizza do you want to make?
";
/////////////////
int quantity;
(cin >> quantity).get();
pizza * guest=new pizza[quantity];
/////////////////
///////////////////////////////////////////////////////////
for (int i=1; i<=quantity; i++)
{
cout << "Enter number " << i << " pizza statistics!
";
cout << "Enter pizza name : ";
cin.getline(guest[i]->name,nameSize);
cout << "Enter pizza diameter : ";
cin >> guest[i]->diameter;
cout << "Enter pizza weight : ";
(cin >> guest[i]->weight).get();
}
///////////////////////////////////////////////////////////
cout << "
Here is your pizza statistics!
";
///////////////////////////////////////////////////////////
for (int i=1; i<=quantity; i++)
{
cout << "Pizza number " << i << endl;
cout << "Name : " << guest[i]->name << endl;
cout << "Diameter : " << guest[i]->diameter << endl;
cout << "Weight : " << guest[i]->weight << endl;
}
///////////////////////////////////////////////////////////
getch();
return 0;
}
Thank you and Happy New Year

Hi Binit,
Firstly you didnt mention what problem are you facing
with the code.. (compiler error.. runtime error? )
The loop range you are using is from 1 to <quantity>.
It should be from 0 to <quantity -1>.

Manik

Mixing struct, pointer and array.
It is a compiler error.
It says:
base operand of `->` has non-pointer type `pizza`

Mixing struct, pointer and array.
Ya, the compiler is right (obviously it had to be
right)
The statement:
pizza * guest = new pizza[quantity];
allocates an array of pizza and makes guest pointer
point to it.
Therefore guest[i] is not a pointer but a pizza
element.
Therefore use the dot (.) operator instead of ->
guest[i].name ....
