+ } + std::string name{}; // defines the public member variable `name` + private: // from here on all members are private + int damage{5}; // defines the private member variable `damage` +}; + +``` + +You can access all member variables from within the class. +Take a look at `damage` inside the `cast_spell` function. +You cannot read or change `private` members outside of the class: + +```cpp +Wizard silverhand{}; +// calling the `cast_spell` function is okay, it is public: +silverhand.cast_spell(); +// => 5 + +// name is public and can be changed: +silverhand.name = "Laeral"; + +// damage is private: +silverhand.damage = 500; + // => Compilation error +``` + +### Constructors + +Constructors offer the possibility to assign values to member variables at object creation. +They have the same name as the `class` and do not have a return type. +A class can have several constructors. +This is useful if you do not always have a need to set all variables. +Sometimes you might want to keep everything at default but change the `name` variable. +In the case of a significant Wizard you might want to change the damage as well, so you need two `constructors`. + +```cpp +class Wizard { + public: + Wizard(std::string new_name) { + name = new_name; + } + Wizard(std::string new_name, int new_damage) { + name = new_name; + damage = new_damage; + } + int cast_spell() { + return damage; + } + std::string name{}; + private: + int damage{5}; +}; + +Wizard el{"Eleven"}; // deals 5 damage +Wizard vecna{"Vecna", 50}; // deals 50 damage +``` + +Constructors are a big topic and have many nuances. +If you are not explicitly defining a `constructor` for your `class`, then - and only then - the compiler will do the job for you. +This has happened in the first example above. +The _silverhand_ object is created by calling the default constructor, no arguments were passed. +All variables are set to the value that was stated in the definition of the class. +If you had not given any values in that definition, the variables might be uninitialized, which might have unintended consequences. + +~~~~exercism/note +## Structs + +Structs came from the language's original C roots and are as old as C++ itself. +They are effectively the same thing as `classes` with one important exception. +By default, everything in a `class` is `private`. +Structs, on the other hand, are `public` until defined otherwise. +Conventionally, the `struct` keyword is often used for **data-only structures**. +The `class` keyword is preferred for objects that need to ensure certain properties. +Such an invariant could be that the `damage` of your `Wizard` `class` cannot turn negative. +The `damage` variable is private and any function that changes the damage would ensure the invariant is preserved. +~~~~ + +## Instructions + +Ellen is making a game where the player has to fight aliens. +She has just learned about Object Oriented Programming (OOP) and is eager to take advantage of what using `classes` could offer her program. + +To Ellen's delight, you have offered to help and she has given you the task of programming the aliens that the player has to fight. + + +## 1. Create the `Alien` Class + +Define the `Alien` class with a constructor that accepts two `int` parameters `x` and `y`, putting them into `x_coordinate` and `y_coordinate` member variables. +Every alien will also start off with a health level of `3`, so the `health` member variable should be initialized as well. + +`health` should be a private member variable. +To let other parts of the program read the health information, Ellen wants to have a `public` `get_health()` method which returns an `int`. + +```cpp +Alien alien{2, 0}; +alien.x_coordinate; +// => 2 +alien.y_coordinate; +// => 0 +alien.get_health(); +// => 3 +``` + +Now, each alien should be able to internally track its own position and health. + +## 2. The `hit` Function + +Ellen would like the Alien `class` to have a `hit` method that decrements the health of an alien object by `1` when called. +This way, she can simply call `some_alien_instance.hit()` instead of having to manually change an alien's health. +Make sure that the health points do not drop below zero. +The function should return `true`. +Ellen wants to introduce shields at a later point, which would then report `false` if the shield is up. + +```cpp +Alien alien {0, 0}; +alien.get_health(); +// => 3 (Initial health value) + +alien.hit(); // Decrements health by 1 point. +alien.get_health(); +// => 2 +``` + +## 3. The `is_alive` Function + +You realize that if the health keeps decreasing, at some point it will probably hit `0`. +It would be a good idea to add an `is_alive` method that Ellen can quickly call to check if the alien is... well... alive. 😉 +`some_alien_instance.is_alive()` should return a boolean. + +```cpp +alien.get_health(); +// => 1 +alien.is_alive(); +// => true +alien.hit(); +alien.get_health(); +// => 0 +alien.is_alive(); +// => false +``` + +## 4. The `teleport` Function + +In Ellen's game, the aliens can teleport! +You will need to write a `teleport` method that takes `x_new` and `y_new` values, and changes the alien's coordinates accordingly. +For the time being, the function should return `true`. +Ellen wants to add teleport-blocking bombs in later levels, which would then report `false` for failed teleporting attempts. + +```cpp +alien.teleport(5, -4); +alien.x_coordinate; +// => 5 +alien.y_coordinate; +// => -4 +``` + +## 5. The `collision_detection` Function + +If the aliens can be hit by something, then they need to be able to detect when such a collision might occur. +Ellen needs to know if two aliens occupy the same coordinates. +The `collision_detection()` function takes another alien object as an argument and returns a `bool`. + +```cpp +Alien lrrr {3, 6}; +Alien ndnd {-2, 12}; +lrrr.collision_detection(ndnd); +// => false +ndnd.teleport(3, 6); +ndnd.collision_detection(lrrr); +// => true +``` + +## Source + +### Created by + +- @vaeng \ No newline at end of file diff --git a/cpp/ellens-alien-game/build/ellens-alien-game b/cpp/ellens-alien-game/build/ellens-alien-game new file mode 100755 index 0000000..072cf14 Binary files /dev/null and b/cpp/ellens-alien-game/build/ellens-alien-game differ diff --git a/cpp/ellens-alien-game/ellens_alien_game.cpp b/cpp/ellens-alien-game/ellens_alien_game.cpp new file mode 100644 index 0000000..8f7f0b0 --- /dev/null +++ b/cpp/ellens-alien-game/ellens_alien_game.cpp @@ -0,0 +1,44 @@ +namespace targets { +class Alien { +public: + Alien(int x, int y) { + x_coordinate = x; + y_coordinate = y; + health = 3; + } + + int get_health() { return health; } + + bool hit() { + if (health > 0) { + health -= 1; + return true; + } + + return false; + } + + bool is_alive() { return health > 0; } + + bool teleport(int x_new, int y_new) { + x_coordinate = x_new; + y_coordinate = y_new; + return true; + } + + bool collision_detection(Alien other_alien) { + if (x_coordinate == other_alien.x_coordinate && + y_coordinate == other_alien.y_coordinate) { + return true; + } + + return false; + } + + int x_coordinate, y_coordinate; + +private: + int health; +}; + +} // namespace targets diff --git a/cpp/ellens-alien-game/ellens_alien_game_test.cpp b/cpp/ellens-alien-game/ellens_alien_game_test.cpp new file mode 100644 index 0000000..34aa689 --- /dev/null +++ b/cpp/ellens-alien-game/ellens_alien_game_test.cpp @@ -0,0 +1,71 @@ +#include "ellens_alien_game.cpp" +#ifdef EXERCISM_TEST_SUITE +#include +#else +#include "test/catch.hpp" +#endif + +using namespace targets; + +TEST_CASE("Alien has correct initial coordinates", "[task_1]") { + Alien alien{2, -1}; + REQUIRE(alien.x_coordinate == 2); + REQUIRE(alien.y_coordinate == -1); +} + +TEST_CASE("Alien has correct initial health", "[task_1]") { + Alien alien{22, 0}; + REQUIRE(alien.get_health() == 3); +} + +TEST_CASE("New alien does not share old aliens position", "[task_1]") { + Alien alien1{22, 0}; + Alien alien2{0, 22}; + REQUIRE(alien1.x_coordinate != alien2.x_coordinate); + REQUIRE(alien1.y_coordinate != alien2.y_coordinate); +} + +TEST_CASE("Alien is always hit", "[task_2]") { + Alien alien{6, 7}; + REQUIRE(alien.hit()); +} + +TEST_CASE( + "Alien is alive while health is greater than 0 and stays dead afterwards", + "[task_3]") { + Alien alien{2, 54}; + REQUIRE(alien.is_alive()); + alien.hit(); + REQUIRE(alien.is_alive()); + alien.hit(); + REQUIRE(alien.is_alive()); + alien.hit(); + REQUIRE(!alien.is_alive()); + alien.hit(); + REQUIRE(!alien.is_alive()); +} + +TEST_CASE("Alien Teleports reports succesful", "[task_4]") { + Alien alien{22, 1}; + REQUIRE(alien.teleport(99, 8)); +} + +TEST_CASE("Alien Teleports where it should", "[task_4]") { + Alien alien{2, -54}; + REQUIRE(alien.x_coordinate == 2); + REQUIRE(alien.y_coordinate == -54); + alien.teleport(99, 8); + REQUIRE(alien.x_coordinate == 99); + REQUIRE(alien.y_coordinate == 8); +} + +TEST_CASE("Alien collision detection with other aliens", "[task_5]") { + Alien alien1{22, 0}; + Alien alien2{0, 22}; + Alien alien3{22, 0}; + REQUIRE_FALSE(alien1.collision_detection(alien2)); + REQUIRE(alien1.collision_detection(alien3)); +} + +#if defined(EXERCISM_RUN_ALL_TESTS) +#endif diff --git a/cpp/ellens-alien-game/test/catch.hpp b/cpp/ellens-alien-game/test/catch.hpp new file mode 100644 index 0000000..36eaeb2 --- /dev/null +++ b/cpp/ellens-alien-game/test/catch.hpp @@ -0,0 +1,17937 @@ +/* + * Catch v2.13.6 + * Generated: 2021-04-16 18:23:38.044268 + * ---------------------------------------------------------- + * This file has been merged from multiple headers.
