Encapsulating state
A small, runnable example of this syntax.
#include <iostream>
class Counter {
public:
void increment() { ++value_; }
int value() const { return value_; }
private:
int value_ = 0;
};
int main() {
Counter counter;
counter.increment();
std::cout << counter.value() << "\n";
}Best practices
- Initialize members in constructors and prefer automatic objects over manually managed resources.
- Keep examples small while learning, then combine the idea with a real project.
