Which of the following is NOT a reason we use subprograms?

Given a vector of students, the function FinalAvg is supposed to return the average final exam score across all the students in

alexandr1967 [171]

Answer:

The C++ code is given below with appropriate comments

Explanation:

#define CATCH_CONFIG_MAIN //This tells Catch to provide a main()

#include"catch.hpp" //Header for Catch Framework

double FinalAvg( vector <int> students) // Function to calculate average.

{

double sum =0;

int i;

for( i=0;i<v.size();i++) sum+= v[i];

return v.empty() ? 0.0 : (double(sum)/ v.size());

}

vector<int> func(int argvq[ ]) // This function is made because we can not provide vector in command line argument that's why we used array which is then conerted into vector.

{

vector<int> v;

int j;

int l= sizeof(argvq)/sizeof(argvq[0]);

for(j=0;j<l;j++)

v.push_back(argq[j]);

return v;

}

TEST_CASE(" Final Average marks are computed","[func]") // TEST_ CASE macro to take one or more arguments

{

REQUIRE( func(9,5,-7) == 7); // We write our individual test assertions using the REQUIRE macro.

REQUIRE(func(2,4,6,-2) ==4);

}

Explanation Using different IDE:

#include<bits/stdc++.h>

using namespace std;

double FinalAvg(vector<int> students)

{

double sum=0;

for(int i=0;i<v.size();i++) sum+= v[i];

return v.empty() ? 0.0 : (double(sum)/v.size());

}

int main()

{

vector<int> v;

int i;

while(cin>>i&&i>0) v.push_back(i);

cout<<Final Avg(v);

return 0;

}

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;

Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have me

RSB [31]

Answer:

Explanation:

The code provided worked for the most part, it had some gramatical errors in when printing out the information as well as repeated values. I fixed and reorganized the printed information so that it is well formatted. The only thing that was missing from the code was the input validation to make sure that no negative values were passed. I added this within the getMonths() method so that it repeats the question until the user inputs a valid value. The program was tested and the output can be seen in the attached image below.

import java.io.*;

import java.util.*;

class Rainfall

{

Scanner in = new Scanner(System.in);

private int month = 12;

private double total = 0;

private double average;

private double standard_deviation;

private double largest;

private double smallest;

private double months[];

public Rainfall()

{

months = new double[12];

}

public void setMonths()

{

for(int n=1; n <= month; n++)

{

int answer = 0;

while (true) {

System.out.println("Enter the rainfall (in inches) for month #" + n + ":" );

answer = in.nextInt();

if (answer > 0) {

months[n-1] = answer;

break;

}

public void getTotal()

{

total = 0;

for(int i = 0; i < 12; i++)

{

total = total + months[i];

}

System.out.println("The total rainfall for the year is " + total);

}

public void getAverage()

{

average = total/12;

System.out.println("The average monthly rainfall is " + average);

}

public void getLargest()

{

double largest = 0;

int largeind = 0;

for(int i = 0; i < 12; i++)

{

if (months[i] > largest)

{

largest = months[i];

largeind = i;

}

System.out.println("The largest amount of rainfall was " + largest +

" inches in month " + (largeind + 1));

}

public void getSmallest()

{

double smallest = Double.MAX_VALUE;

int smallind = 0;

for(int n = 0; n < month; n++)

{

if (months[n] < smallest)

{

smallest = months[n];

smallind = n;

}

System.out.println("The smallest amount of rainfall was " + smallest +

" inches in month " + (smallind + 1));

}

public static void main(String[] args)

{

Rainfall r = new Rainfall();

r.setMonths();

r.getTotal();

r.getSmallest();

r.getLargest();

r.getAverage();

}
