3. Write a function called e2_age_range that computes how many people fall within a certain age range. The first input, A, is a matrix of non-negative integers specifying the ages of a group of people. The second input, called min_age, is the age the included people must be older than. The third, max age, is the age the included people cannot be older than. The function returns the number of people that fall into the specified range. You are not allowed to use loops. Here are some example runs: > e2_age_range ([12 8 22 18 17 3 4 33],0,17) ans = >> e2_age_range (1:100,90 ,100) ans = 10 > e2_age_range ([1 3 5 7 9],5,6) ans =

To convert between Celsius and Fahrenheit, the following formula is used, where C = Celsius temperature and F = Fahrenheit temperature: C = 5/9 * (F-32) Write a C++ temperature conversion program which does the following: Write a function called toCelsuis which takes a Fahrenheit temperature as a parameter, and returns the equivalent Celsius temperature: float toCelsius(float) Demonstrate that your function works by writing a main() function that prints out a conversion table. It should have Fahrenheit values 60, 61, 62, ... through 80 (21 temperatures in total) and should also have the corresponding Celsius temperatures that your function calculated. So your output should look something like this (with 21 temperature conversions total, I used ... to save space here for most of them): Welcome to the temperature table!F C60 15.661 16.1... ...80 26.7 If you like: you can add this line in your function to make floating point output fixed, make sure you…

Write a function dispense_bills(). The function determines the minimum number of bills to dispense given a withdrawal amount. The possible bills dispensed include: 50’s, 20’s, and 10’s. The number of each bill to dispense should be stored indirectly through the pointers: fifties_ptr, twenties_ptr, and tens_ptr. If the withdrawal_amount exceeds the balance, then the number of each bill to dispense should be set to 0, and 0 should be returned. If the withdrawal_amount is less than or equal to the balance, then the number of each bill to dispense should be calculated, and 1 should be returned. The function header has been provided for you. // precondition: withdrawal amount must be a multiple of 10 // return: 1 if the balance >= withdrawal_amount; 0 otherwise int dispense_bills(double balance, double withdrawal_amount, int *fifties_ptr, int *twenties_ptr, int *tens_ptr) { }
Age information for 100 families of 4 people is defined as members of a community. For every family,  Send the age of each family member to a function called average (), where the average is after calculating, send the address of the average information to the main() function, main the function prints,  Send the addresses of parents ' age information to function1 (), in the function, it checks whether the ages of the mother and father are double, and each if the age of both is even, it returns a value of 1 from the function, otherwise a value of 0,write a C program.
we will write a function to compare the suitability of various alien planets for a space colony. Make up the names of 5 alien planets and enter these in cells B5–B9 of Sheet 1 in your file. For each planet make up in the same row of the sheet a temperature (between -200 and +200) in column C, an oxygen percentage (between 0 and 100) in column D, and a radiation level chosen from “None”, “Low”, “High”, and “Lethal” in column E. Write a function which takes as input a planet name and returns a message as follows: • If the planet is not on the list then return “Pick another planet”. • If the temperature is less than -80 or greater than +80, or the oxygen level is less than 10, or the radiation level is Lethal, return “x is not habitable” where x is the name of the planet.
Assume that we have a function "double getDistance(struct point p1, struct point p2)" that calculates the euclidian distance (straight line distance) between point p1 and p2. The point structure has two floating point variables x and y. You need to write the getDistance function here?
Hello, I need help please because I am trying to make a function that will count the wins of a team and output the wins. The function prototype is unsigned wins(); It takes no parameter and it shall search the games_ vector and return the number of wins. Were supposed to not use the [] operator, but I dont know how else to do it. Here is my code for context: TEAMS.H FILE #ifndef TEAMS_H#define TEAMS_H#include <vector>#include <iostream>#include <string>#include "Game.h"using namespace std; class Teams { private: string team_name_; vector <Game> games_; public: Teams(const string& new_team); void addGame(const string&, const string&); void removeGame(const string&); void updateScores(const string&, unsigned, unsigned); unsigned wins(); friend ostream& operator<<(ostream&, const Teams&);};#endif TEAMS.CPP FILE: #include <iostream> #include <vector>#include <string>#include "Teams.h"…
4.16 LAB: Toll calculation Toll roads have different fees based on the time of day and on weekends. Write a function calc_toll() that has three parameters: the current hour of time (int), whether the time is morning (boolean), and whether the day is a weekend (boolean). The function returns the correct toll fee (float), based on the chart below. Weekday Tolls Before 7:00 am ($1.15) 7:00 am to 9:59 am ($2.95) 10:00 am to 2:59 pm ($1.90) 3:00 pm to 7:59 pm ($3.95) Starting 8:00 pm ($1.40) Weekend Tolls Before 7:00 am ($1.05) 7:00 am to 7:59 pm ($2.15) Starting 8:00 pm ($1.10) Ex: The function calls below, with the given arguments, will return the following toll fees: calc_toll(8, True, False) returns 2.95calc_toll(1, False, False) returns 1.90calc_toll(3, False, True) returns 2.15calc_toll(5, True, True) returns 1.05
4. Write a function called electionResults() that takes 2 lists as parameters. Thefirst list contains the names of political parties, in a given order; the second contains, inthe same order, the vote total each party received in a local election. Your function should print the name of each party followed by the word “Party”, in a column 30characters wide; the number of votes each received in a column 10 characters wide; andthe percentage of the vote each received in a column 10 characters wide, rounded to 2decimal places, followed by the percent sign ‘%’. (Vote totals may not add to exactly100.00% because of rounding.)>>> electionResults(['Sensible', 'Silly', 'Very Silly'], [29412,29397, 37])Sensible Party 29412 49.98%Silly Party 29397 49.96%Very Silly Party 37 0.06%
Please provide step by step solution with a proper explanation. C++ Question: Write a function named "countGrades" that will accept a count as the total number of grades to be read in by the function. After reading the list of grades, it will return the following statistical data for that list of grades: - how many grades are passing ('A' or 'B' or 'C') - how many 'A' grades - how many invalid grades (not 'A', 'B', 'C', 'D' or 'F') For example, if the user passes in 1 and enters 'A', it will return 1, 1, 0 If the user passes in 3 and enters 'A', 'B', 'C', it will return 3, 1, 0 If the user enters in 5 and enters 'A', 'B', 'C', 'X', 'A', it will return 4, 2, 1
‘Write a function get_names(), which prompts the user for a sequence of names, where each name can contain an arbitrary mix of uppercase and lowercaseletters and space characters, until the user enters "exit". The function should then return a list of capitalized names, whith no leading or trailing space, and with‘one space character separating adjacent words, Write a main() function to test the get_names() function.
