Write a program that simulates flipping a coin repeatedly and continues until three consecutive heads. are tossed. At that point

quester [9]

Answer and Explanation:

#include <iostream>

#include <string>

#include <time.h>

#include <vector>

using namespace std;

//Takes user info

int user_info(string *name,char *gender){

char G;

cout<<"What is your name?: ";

getline(cin, *name);

cout<<"What is your gender(m/f):";

cin>>G;

cout<<endl;

*gender = tolower(G);

return 0;

}

//Toss coin(part 2)

bool coin_toss(double seed){

double r;

r = (double)seed/(double)RAND_MAX;

//cout<<r;

if (r<0.5) return true;

return false;

}

//check results

float toss_result(vector<char> v,int *h){

int num_heads=0;

int num_toss = v.size();

*h = 0;

for(int i=0;i<num_toss;i++){

if(v[i]=='h'){num_heads++;(*h)++;}

}

return (float)num_heads/(float)num_toss;

}

void show_result(int total_num,int head_num,float ratio){

cout<<"it took you "<<total_num<<" tosses to get 3 heads in a row"<<endl;

cout<<"on average you flipped heads "<<(ratio*100)<<"% of the time"<<endl;

}

int main()

{

string name;

char gender;

string K; //Mr or Mrs

cout<<"Welcome to coin toss! Get 3 heads in row to win!"<<endl;

//part 1

user_info(&name,&gender);

if(gender == 'f') K = "Mrs.";

else K = "Mr.";

cout<<"Try to get 3 heads in a row. Good luck "<<K<<name<<"!"<<endl;

char dummy = getchar();

//part 2

int num_toss;

vector<char> toss_results;//store toss results

bool result;//result of toss

srand(time(0));

while(true){

//cout<<rand()<<endl;

result = coin_toss(rand());

cout<<"Press <enter> to flip"<<endl;

while (1)

{

if ('\n' == getchar())

break;

}

if(result) {toss_results.push_back('h');cout<<"HEAD"<<endl;}

else {toss_results.push_back('t');cout<<"TAIL"<<endl;}

num_toss = toss_results.size();

if(num_toss>=3){

if ((toss_results[num_toss-1] == 'h')&&(toss_results[num_toss-2] == 'h')&&(toss_results[num_toss-3] == 'h')){

break;

}

//part 3

float ratio_head;

int num_of_heads;

ratio_head = toss_result(toss_results,&num_of_heads);

//part 4

show_result(toss_results.size(),num_of_heads,ratio_head);

return 0;

}

Please save the program with the name ‘triangle.c’

konstantin123 [22]

Answer:

1. #include <stdio.h>

2. int main()

3. {

4. int k;

5. int j;

6. int i;

7. int array[7];

8. array[0] = 1;

9. for (i = 1; i < 9; ++i)

10. {

11. array[i] = array[i-1]*2;

12. for (j=0; j < i; ++j)

13. {

14. printf("%d ",array[j]);

15. }

16. for (k=i-2; k > -1; --k)

17. {

18. printf("%d ", array[k]);

19. }

20. printf("\n");

21. }

22. return 0;

23. }

Explanation:

From line 1 to 3 we start the main function
From line 4 to 7 we declare the variables that we are going to be using throughout the program including an array of 7 positions
On line 8 we initialize the array with one to match the sequence
From line 9 to 10 we create a for loop to create the 9 sequences of numbers
On line 11 we assign values to the array by taking the previous value and multiplying it by 2, this way we can create the sequence 1,2,4,8,32...
From line 12 to 15 we print the ordered array
From line 16 to 19 we print the inverse array minus one
On line 20 we print an enter
