in C++, I must input 3 weather values (temperature low, temperature high, rain)

Question

in C++, I must input 3 weather values (temperature low, temperature high, rain) and output the following: days reported, min temp, max temp, avg low, avg high, total rain and number of rainy days. This all must take place in a while loop in the function main. This program will also input from a text file. I am also not to use a prompt for input. so far I have:

#include <iostream>

using namespace std;

int main()

{

int tempHigh, tempLow, reportedDays=0, min=0, max=0, count=0, rainyDays=0;

double rain, avgLow=0, avgHigh=0, totRain=0, sumMin=0, sumMax=0;

while (reportedDays<=10)

{

cin >> tempHigh >> tempLow >> rain;

count++;

if (tempLow<min)

tempLow=min;

if (tempHigh>max)

tempHigh=max;

sumMin=sumMin+tempLow;

avgLow=sumMin/reportedDays;

sumMax=sumMax+tempHigh;

avgHigh=sumMax/reportedDays;

totRain=totRain+rain;

if (rain>0)

rainyDays=reportedDays;

}

cout << endl;

cout << "Days reported = " << reportedDays;

cout << "Min temp = " << min;

cout << "Max temp = " << max;

cout << "Avg low = " << avgLow;

cout << "Avg high = " << avgHigh;

cout << "Total rain = " << totRain;

cout << "Number of rainy days = " <<rainyDays;

return 0;

}

Explanation / Answer

// This opens a text file name input.txt within your program folder. It counts the input from the file as part of your 11 days. (since you start your loop at 0 and go until equal or less than 10 it makes it 11 days.) Only thing I changed in your subitted code was count = reportedDays and days of rain is added separately not equal to reported Days.

#include <iostream>
#include <fstream>
#include <cstdlib>

using namespace std;

int main()

{

int tempHigh, tempLow, reportedDays=0, min=0, max=0, count=0, rainyDays=0;

double rain, avgLow=0, avgHigh=0, totRain=0, sumMin=0, sumMax=0;

// *********************************** Reading an input file ********************************************
ifstream inFile;
string filename;

   filename = "input.txt";

   inFile.open(filename.c_str());

   if (inFile.fail())
   {
       cout << " The file was not successfully opened"
           << " Please check that the file path is correct."
           << endl;
       cout << endl;
       exit(1);
   }

   cout << " The file has been successfully opened for reading."
       << endl;
   cout << endl;

// ************** Read your values

inFile >> tempHigh >> tempLow >> rain;
while(inFile.good())
{
cout << tempHigh << " " << tempLow << " " << rain << endl;
inFile >> tempHigh >> tempLow >> rain;
count++;
}

inFile.close();

// **************************************** End of input file *******************************************************************************

while (reportedDays<=10)
{
cin >> tempHigh >> tempLow >> rain;
count++;
reportedDays = count;
if (tempLow<min)
tempLow=min;
if (tempHigh>max)
tempHigh=max;
sumMin=sumMin+tempLow;
avgLow=sumMin/reportedDays;
sumMax=sumMax+tempHigh;
avgHigh=sumMax/reportedDays;
totRain=totRain+rain;

if (rain>0)
rainyDays += 1;
}

cout << endl;
cout << "Days reported = " << reportedDays << endl;
cout << "Min temp = " << min << endl;
cout << "Max temp = " << max << endl;
cout << "Avg low = " << avgLow << endl;
cout << "Avg high = " << avgHigh << endl;
cout << "Total rain = " << totRain << endl;
cout << "Number of rainy days = " <<rainyDays << endl;

return 0;
