difference b/w object and class?

Answer 1

A class is a block of code where one would store variables and functions. For example, when creating a game, you may have a class for enemy, which contains variables such as health and attack power, or functions such as attack(). Classes also have three different access specifiers you can use - public, private and protected. Use the SoloLearn modules on this to learn the difference between the three, otherwise this would be a very long answer.

An object is simply a way how one would access members of that particular class. You can have more than one object for a single class, and each object will holds its own variables. For example, if you had int 'a' in the class, object1 could have 'a' with a value of 5, where as object2 could have 'a' with a value of 10.

Example:

#include <iostream>
using namespace std;

class enemy
{
public:
void setAp(int ap)
{
attackPower = ap;
}

void attack()
{
cout << "Enemy does " << attackPower << " damage!";
}

private:
int attackPower;
};

int main()
{
enemy obj;
obj.setAp(5);
obj.attack();
}

Answer 2

A class defines how to create an object. An object is an instance of a class, that you can use concretely. Think of the class as a blueprint and an object of the class as something built from it.

Answer 3

the class is a recipe the object is the food.
