Question

C++ Create a .h file, .cpp file, and main file and zip them together, try not to use structs.

Create a simulation of a game call "target darts". The target has a center at 0,0 and there are concentric circles around that center, each with a radius 2 more than the previous one. So there are circles with radius 2, 4, 6, 8 etc. Assume a player can throw 4 darts at the target, the distance the dart lands from the center is random, (but positive double) with mean = 0 standard deviation = 3. Each dart is scored as 10-next nearest inner circle. That is if the dart ends up at 3.9 away from the center, the next circle closer to the center is radius 2. (4 is further away not closer to the center) so the player scores 10-2 or 8 points. If the player throws the dart and it lands 7.88 away, the next closer circle is 6, so the player scores 10-6 or 4 points. Print to the screen each of the four throws and the result as well as the total score, example output follows. Next Circle Score Dart# Distance 1.8 25.9 12.1 9.3 Total score 3 4. 00

Here is the C++ code for each file:

TargetDarts.h:

#ifndef REPLACE_TARGETDARTS_H #define REPLACE_TARGETDARTS_H class TargetDarts { private: double d1,d2,d3,d4; int s1,s2,s3,s4; public: void simulate(); void print(); }; #endif 

Screenshot:

#ifndef REPLACE_TARGETDARTS_H #define REPLACE_TARGETDARTS_H class TargetDarts { pvate: double d1, d2, d3, d4; int 51, 52, 53, 54; public: void simulate(); void print(); }; #endif 95 105 . 11 12

TargetDarts.cpp:

#include <random> #include <iomanip> #include "TargetDarts.h" using namespace std; void TargetDarts::simulate() { normal_distribution<double> dis(0.0,3.0); default_random_engine gen; d1 = abs(dis(gen)); d2 = abs(dis(gen)); d3 = abs(dis(gen)); d4 = abs(dis(gen)); s1 = floor(d1); s2 = floor(d2); s3 = floor(d3); s4 = floor(d4); if(s1%2 == 1) s1-=1; if(s2%2 == 1) s2-=1; if(s3%2 == 1) s3-=1; if(s4%2 == 1) s4-=1; } void TargetDarts::print() { cout<<setprecision(2); int totalScore = 40 - (s1+s2+s3+s4); cout<<"Dart#\tDistance\tNext Circle\tScore"<<endl; cout<<"1 "<<d1<<"\t\t"<<s1<<"\t\t"<<10-s1<<endl; cout<<"2 "<<d2<<"\t\t"<<s2<<"\t\t"<<10-s2<<endl; cout<<"3 "<<d3<<"\t\t"<<s3<<"\t\t"<<10-s3<<endl; cout<<"4 "<<d4<<"\t\t"<<s4<<"\t\t"<<10-s4<<endl; cout<<"_________________________________________________________________________________"<<endl; cout<<"Total Score "<<totalScore<<endl; } 

4 5 # #include <random> #include <iomanip> #include "TargetDarts.h" using namespace std; void TargetDarts :: simulate() { normal distribution double> dis( mean: 0.0, stddev: 3.0); default_random_engine gen; d1 = abs(dis( &: gen)); d2 = abs(dis &: gen)); d3 = abs(dis( &: gen)); = abs(dis( &: gen)); floor(d1); 2 = floor(d2); s3 = floor(dB); 54 = floor(04); if(s1%2 == 1) s1-=1; if(s2%2 == 1) s2-=1; if(s3%2 == 1) s3-=1; if(s4%2 == 1) s4-=1; =} 20 22 # void TargetDarts::print() { cout<<setprecision n: 2); int totalScore = 40 - (51+s2+3+54); cout<<"Dart#\tDistance tNext Circle\tScore"<<endl; cout<<"1 "<<d1<<"\t\t"<<s1<<"\t\t"<<10-51<<endl; cout<<"2 "<<d2<<"\t\t"<<s2<<"\t\t"<<10-52<<endl; cout<<"3 "<<d3<<"\t\t"<<s3<<"\t\t"<<10-53<<endl; cout<< "4 "<<d4<<"\t\t"<<s4<<"\t\t"<<10-54<<endl; cout<<"__ cout<<"Total Score "<<totalScore<<endl; "<<endl;

main.cpp:

#include <iostream> using namespace std; #include "TargetDarts.cpp" int main(){ TargetDarts targ; targ.simulate(); targ.print(); }

3 #include <iostream> using namespace std; #include "TargetDarts.cpp" int main() { TargetDarts targ; targ. simulate(); targ.print();

Here is the OUTPUT for the same:

Dart# Next Circle Score 0 - 2 3 4 Distance 0.37 3.3 2.1 3.2 3 2 0 | Total Score
