Instructions Assume we collected weather temperature data from a city for 5 day, Mon thru Fri. The data is record in a 10 array. Each day is represented with 3 data points. So, create an array with 15 "unsigned short" items, and fill this array with random numbers from 32 to 120. Let's call this array temp array. Then create a structure to keep 1) name of day, and 2) average of temp of this array. Since we have five days, you need to create an array of struct as depicted below. Each row of this array keep a struct (the day and corresponding average temp of this day, Monday thru Friday) as a struct (gray box of array) Day Ave Here Day is name of the day, such as "Monday", and Ave is float variable and average of this day calculated from temp array. For the first day, (Monday), the average will be average of temp array indexes (0]. (1), and (2), Tuesday's average will be average of indexed (3), (4), and (5). Fill all averages using data from array with a loop (not manual). Fill out names of days manually, and print the day:ave pairs on screen. The output should be similar to Monday, average temp with 55.6 Tuesdayaverage temp with 45.5 Wednesday, average temp with 75.0 Thursday, average temp with 75 Friday, average temp with 86.6

C++ Program:

#include <iostream>
#include <iomanip>
#include <cstdlib>
#include <ctime>

using namespace std;

//Structure
struct Temperature
{
string day;
float ave;
};

//Function that returns average
float getAverage(unsigned short temps[15], int idx)
{
float sum = 0;
int i;
  
//Looping
for(i=idx; i<idx+3; i++)
{
sum = sum + temps[i];
}
  
return (sum/3.0);
}

//Main function
int main()
{
int i, j;
int max=120, min=32;
unsigned short temp[15];
  
srand(time(0));
  
//Creating array of structures
struct Temperature days[5];
  
cout << fixed << setprecision(1);
  
//Generating random values
for(i=0; i<15; i++)
{
temp[i] = rand()%(max-min + 1) + min;
}
  
//Filling structures
days[0].day = "Monday";
days[0].ave = getAverage(temp, 0);
  
//Filling structures
days[1].day = "Tuesday";
days[1].ave = getAverage(temp, 3);
  
//Filling structures
days[2].day = "Wednesday";
days[2].ave = getAverage(temp, 6);
  
//Filling structures
days[3].day = "Thursday";
days[3].ave = getAverage(temp, 9);
  
//Filling structures
days[4].day = "Friday";
days[4].ave = getAverage(temp, 12);
  
//Printing values
for(i=0; i<5; i++)
{
cout << endl << days[i].day << ", average temp with " << days[i].ave;
}
  
cout << endl;
  
return 0;
}

Sample Run:

Monday, average temp with 73.0 Tuesday, average temp with 75.7 Wednesday, average temp with 89.3 Thursday, average temp with 82.0 Friday, average temp with 44.3
