What's wrong with my structure?

HelloWorld · #1 (**permalink**) 08-02-2007, 02:18 PM

here's the code that I have, it shows me an error, but I've no clue why...

PHP Code:

  #include <iostream>
#include <string>
using namespace std;
struct account() {
string name;
int acc_no;
double balance;
};
int main() {
account acc;
acc.name = "test";
acc.acc_no = 123;
acc.balance = 999999;
cout << acc.name << endl;
}

does anybody have a good explanation of what is structure? why do we want to use it? is it similar with abstract class in java?

it seems like it to me... but haven't tried to inherit it...

First, you should always include any error messages.

Second, I believe that struct account() { should be struct account {

struct and class are both the same thing in C++. With one minor caveat. The default access specifier for members of a class is private. the default access specifier for members of a struct is public. Otherwise, they're identical.

struct was inherited from 'C', which had no notion of OOP or classes, so, as a tradition/convention, the struct keyword is only used when the struct only contains data (And maybe some extremely trivial constructors or methods). eg, a coordinate struct for holding 2D 'x' and 'y' values in a graph

Code:

struct coordinate
{
    int x;
    int y;
    coordinate(int xx, int yy)
    {
        x = xx;
        y = yy;
    }
}; //Don't forget the semicolon
