/*Example of a very simple turn based combat system suitable for rpgs or other types of turn based games. this program simulates a battle to the death (or time-out) between the player and the enemies. the battle will continue until either all the enemies or all the players are dead. please if you like this code and you are on sololearn please leave a like and follow me to see more stuff n that. Just Hit Run no input required! Enjoy! ~jay TO DO: allow human players to attack a specific computer player target from a menu system. */ #include #include #include #include #include #include using std::cout; using std::string; using std::ostringstream;
