Struct

This program demonstrates structures (struct), which are similar to classes but with public access by default. They are commonly used for grouping related data.

Implementation

#include <iostream>

struct Point {
    int x, y;
};

int main() {
    Point p1 = {3, 4};
    std::cout << "Point coordinates: (" << p1.x << ", " << p1.y << ")" << std::endl;
    return 0;
}

Key Concepts

• Struct: A user-defined type that groups related variables
• Default Access: Struct members are public by default (unlike classes)
• Aggregate Initialization: 4 initializes struct members in order
• Structs are commonly used for simple data containers

Struct vs Class

The main difference between struct and class is the default access level:

• struct: Members are public by default
• class: Members are private by default

Output

Point coordinates: (3, 4)
