   C++ need help! functions
  hi guys trying to re-write one of my current games so that the code is easier to read and easier to modify but i am stuck.#include <iostream>int choice;double combat_options();int hit_chance;double monster_health = 50;double player_damage_crushing = 15;double combat();int main(){using namespace std;cout << " hello and welcome to player vs monster ";cout << " You are a warrior and suddenly a monster jumps out and attacks you! ";intro();combat_options();combat();cin.get();return 0;}double combat_options(){using namespace std;cout << " what do you do? \n"<< " 1) crushing blow ";return choice;}double combat(){using namespace std;if (hit_chance % 100 < 75){cout << " you have succesfully hit the monster for crushing blow";monster_health -= player_damage_crushing;cout << "Monsters health :" << monster_health;}else{cout << " you have missed the monster... ";}return monster_health;}please help me :Dcan someone show me how to incorporate a do{ } while() loop so that it repeats combat options untill monster or player is dead?   
  the syntax goes like so:do { <things-to-do> } while (cond);with cond being the condition, which is of type "int", so it can be read as code]do { <things-to-do> } while (0 != (cond));(in C and C++, this is the same for all conditions).Note that the <things-to-do> are executed once before the condition is tested. Note that the other form is while (cond) { <things-to-do> }Here, the condition is always tested first, and only after cond!=0 or cond==true, the <things-to-do> are executed.In other words, in the while(){} form (called a "pre-test loop"*), the body is executed at least 0 times, in the do{}while() form (called a "post-test loop"*), the body is executed at least 1 time.*: Anecdote: In german, we say "head controlled loop" ("kopfgesteuerte Schleife") and "foot controlled loop" ("fußgesteuerte Schleife")   ;Quote:Original post by phresnelwith cond being the condition, which is of type "int"In C++ it's bool.
