java - Threeway Duel to the Death -

working on project intro java class, heres gist of needs --

in land of puzzlevania, aaron, bob, , charlie had anargument on 1 of them greatest puzzler of time. endthe argumentonce , all, agreed on duel death. aaronis poor shooter , hits target probability of 1/3. bob isa bit better , hits target probability of 1/2. charlie expertmarksman , never misses. hit means kill , person hit drops outof duel. compensate inequities in marksmanship skills, itis decided contestants fire in turns starting aaron,followed bob, , charlie. cycle repeat until there oneman standing. , man remembered greatest puzzlerof time.

a. write function simulate single shot. should usethe following declaration: voidshoot(bool& targetalive, double accuracy, int&num_alive); simulate shooting @ targetalive thegiven accuracy generating random number between 0 , 1. if therandom number less accuracy, target hit andtargetalive should set false. appendix 4 illustrates how generate randomnumbers. example, if bob shooting @ charlie, invokedas: shoot(charliealive,0.5, num_alive); here, charliealive boolean variable indicates if charlieis alive. test function using driver program before moving on stepb.

b. obvious strategy each man shoot @ accurate shooter still alive on grounds shooter deadliest , has best chance of hitting back. write second function named start duel uses shoot function simulate entire duel using strategy. should loop until 1 contestant left, invoking shoot function proper target , probability of hitting target according shooting. function should return variable indicates won duel.

c. in main function, invoke startduel function 1,000 timesin loop, keeping track of how many times each contestant wins. output probability each contestant win wheneveryone uses strategy of shooting @ accurate shooter left alive.

d. counter intuitive strategy aaron intentionally misson first shot. thereafter, uses strategy of shooting atthe accurate shooter left alive. strategy means aaron guaranteed live past first round, since bob , charlie fire @ each other. modify program accommodate new strategy , output probability of winning each contestant.

so here code i'm working with... far goes through once, i'm not sure should put loop? other pointers in code appreciated.

the answer of question written in requirements problem:

c. in main function, invoke startduel function 1,000 timesin loop, keeping track of how many times each contestant wins. output probability each contestant win when uses strategy of shooting @ accurate shooter left alive.

// main() pseudocode: shooter[] shooters = new shooter[3](); // or java syntax ... // set strategy, name each of 3 shooters... shooters[0].setname(".."); shooters[0].setstrategy(...); // ...  // storage count player wins round... int[] wincounters = new int[3]; for( int = 0; < 1000; i++ ) {      int winner = startduel(shooters); // returns index of winner...      wincounters[winner]++; } // ... output statistics ....
