Classes and objects
A class is a blueprint that bundles data and behavior together. An object is one thing built from that blueprint, the way many houses can be built from one plan.
Variables inside a class are called members, and functions inside it are called methods. Put them after public: so code outside the class can use them.
Create an object like any variable, Dog rex;, then use a dot: rex.name = "Rex"; and rex.bark();. A class definition ends with a semicolon after its closing brace.
Example
class Dog {
public:
std::string name;
void bark() {
std::cout << name << " says woof!" << std::endl;
}
};
int main() {
Dog rex;
rex.name = "Rex";
rex.bark();
return 0;
}Output
Rex says woof!
Forgetting the semicolon after a class's closing brace is one of the most common C++ errors.
