Question

15. a. Write a program to process a collection of daily high temperatures.
Your program should count and print the number of hot days (high
temperature 85 or higher), the number of pleasant days (high tem-
perature 60-84), and the number of cold days (high temperature less
than 60). It should also display the category of each temperature.

Test your program on the following data:
55 62 68 74 59 45 41 58 60 67 65 78 82 88 91
92 90 93 87 80 78 79 72 68 61 59

b. Modify your program to display the average temperature (a real
number) at the end of the run.

//create file for following data
Test your program on the following data: 55 62 68 74 59 45 41 58 60 67 65 78 82 88 91 92 90 93 87 80 78 79 72 68 61 59 and use this file
Can you solve this problem with creating file and using
#include ifstream inF; string name; please.............. I will really appreciate you i will definetly rate life saver thanks

Explanation / Answer

put temperature file in the same folder with your .cpp file

#include <iostream>
#include <string>
#include <fstream>

using namespace std;

//PROTOTYPES

int main()
{
   //LOCAL DECLARATIONS
   ifstream inF;
   string name;
   int temp;
   int hotDays = 0;
   int normalDays = 0;
   int coldDays = 0;
   int tempSum = 0;
   int tempCount = 0;


   cout << "Enter file name: ";
   cin >> name;

   inF.open(name.c_str()); //you need cstring or character array to open file
   if (!inF)
   {
      cerr << "Cannot open file ";
      exit(1);
   }

   while (inF >> temp)
   {
      if (temp >= 85)
         hotDays++;
      else if (temp < 60)
         coldDays++;
      else
         normalDays++;
      tempSum += temp;
      tempCount++;
   }
   inF.close();

   cout << " Number of hot day(s): " << hotDays << endl
        << "Number of pleasant day(s): " << normalDays << endl
        << "Number of cold day(s): " << coldDays << endl
        << " Average temperature: " << (double)tempSum / tempCount << endl;

   cout << endl;
   return 0;
}
