Question

Write a program that demonstrates use of programmer - defined data structures. Please provide code! Thank you.

Janual line Iranin Note: This program is similar to another recently assigned program, except that it uses struct and an array of structs instead of parallel arrays to hold the data. Objective: Write a program that demonstrates use of programmer-defined data structures (structs), an array of structs, passing an array of structs to a function, and returning a struct as the value of a function. A function in the program should read several rows of data from a text file. (The data file should accompany this assignment.) Each row of the file contains a month name, a high temperature, and a low temperature. The main program should call another function which finds and returns a struct which contains the month with the highest temperature, and another function to do the same with the lowest temperature. The main program should output the highest and lowest temperatures for the year, along with the month names that correspond to those temperatures. • The program should define a struct that holds a month name, a low temperature (an int) and a high temperature (an int). The program should define an array of such structs. The number of elements in that array should be established using a named constant of type int. This value should be sufficient to store all of the data records from the provided data file. Your program MUST use the following functions: Function loadData: The function reads data from a text file (temps.txt) and stores the data in an array of structs. int loadData( ifstream &infile, Temperature [], int &rows) (Note that the last parameter returns the number of rows of data actually read from the file.) Function find Low: This function finds the month that has the lowest temperature and returns a copy of the struct containing that information. Temperature findLow Temperature [l, int rows) Function find High: This function finds the month that has the highest temperature and returns a copy of the struct containing that information. Temperature findHigh( Temperature (1, int rows)

Here are the temps given:

January 47 36
February 51 37
March 57 39
April 62 43
May 69 48
June 73 52
July 81 56
August 83 57
September 81 52
October 64 46
November 52 41
December 45 35

temperature.cpp

#include <iostream>
#include <fstream>
#include <iomanip>

using namespace std;

//struct for temp
struct Temperature
{
//variables
string month;
int high;
int low;
};

//load from file
int loadData(ifstream &infile, Temperature t[], int &rows)
{
infile.open("C:/Users/NIROSHINI/Desktop/input.txt");
int n=0;

//if no file, print error msg
if(!infile)
{
cout<<"No input file found";
return 0;
}
//read from file
while(!infile.eof())
{
infile>>t[n].month>>t[n].high>>t[n].low;
n++;
}
rows=n; //set rows
  
cout<<"\nfound "<<n<<" months of data\n";
//print data on screen
for(int i=0;i<rows;i++)
cout<<setw(9)<<t[i].month<<" "<<t[i].high<<" "<<t[i].low<<endl;

infile.close(); //close file
return n; //return row size
}

//return lowest avg temperature
Temperature findLow(Temperature t[],int rows)
{
int low=999;
int index;

//find lowest temp
for(int i=0;i<rows;i++)
{
if(low>(t[i].low+t[i].high)/2){
low=(t[i].low+t[i].high)/2;
index=i;
}
}
return t[index]; //return temp
}

//return highest avg temperature
Temperature findHigh(Temperature t[],int rows)
{
int high=0;
int index;

//find highest temp
for(int i=0;i<rows;i++)
{
if(high<(t[i].low+t[i].high)/2){
high=(t[i].low+t[i].high)/2;
index=i;
}
}
return t[index]; //return temp
}

int main()
{
ifstream infile; //file
struct Temperature t[12],t1,t2; //temp obj
int rows; //rows

cout<<"This program finds the warmest and coldest months as listed in a data file.";
cout<<"\n<loadData called>";

rows=loadData(infile,t,rows); //load from file

//if no data close the program
if(rows==0){
cout<<"No data available";
return 0;
}

cout<<"\n<averageHigh called>";
t1=findHigh(t,rows); //find the highest avg temp
cout<<"\nThe highest average temperature was "<<((t1.high+t1.low)/2)<<" in "<<t1.month<<endl;

//find the lowest avg temp
cout<<"\n<averageLow called>";
t2=findLow(t,rows);
cout<<"\nThe lowest average temperature was "<<((t2.high+t2.low)/2)<<" in "<<t2.month<<endl;

return 0;
}

output:

This program finds the warmest and coldest months as listed in a data file.
