#includeIn this code example, we create a new Game object and call the DoCompleteAchievement function with the argument "First Blood" to complete the achievement of the same name. We then output a message to the console to inform the player that the achievement has been unlocked. Package Library: Based on the code example, it appears that the package library used is called "game.h" which likely contains the Game class and the DoCompleteAchievement function. However, without more context or information about the package library, it is difficult to determine the exact package library used.#include "game.h" //package library int main() { Game myGame; //initialize game object myGame.DoCompleteAchievement("First Blood"); //complete achievement std::cout << "Achievement unlocked: First Blood!" << std::endl; //output message return 0; }
