Write a C++ program: - The text file (city-temps) is a list of weather statistic

Question

Write a C++ program: - The text file (city-temps) is a list of weather statistics for various US cities. Each line has 9 tab-separated fields that can be read using the stream-in operator.

City name
January average temperature in degrees Fahrenheit
April average temperature
July average temperature
October average temperature
Average annual precipitation in inches
Average annual days of rain
Average annual snowfall in inches
--Years of observations used to compile the statistics: rain[/snow]
--The first line in the file is the field names, which can be ignored. Cities with multiple words in their names, such as New York, have the words connected with underscores, New_York, so the city name can be read with a single stream-in request. The only whitespaces in the file are the tab field separators.

Write a C++ program to read the file and calculate the average annual temperature for the city by averaging the four seasonal temperatures. Display the names and temperatures of the cities with the highest and lowest average annual temperatures. The output should look like:
number of cities examined:____
________ has the minumum average annual temperature of _____
________ has the maximum average annual temperature of _____

I am not sure how to upload a text file, so I copied and pasted it below. The text file named as city-temps

Explanation / Answer

//Following is C++ program for given problem statement :

#include <sstream>
#include <iostream>
#include <fstream>
#include <string>
#include <limits>
using namespace std;
int main()
{
   ifstream infile;
   infile.open("city-temps.txt"); // opening city-temps file in read mode
   string name,line;
   string max_name;
   string min_name;
   double a, b,c,d,avg,min_ans=numeric_limits<double>::max(); //initializing min_ans to maximum value
   double max_ans=numeric_limits<double>::min(); //initializing max_ans to minimum value
   int count=0;
   while(getline(infile,line))  
   {
       count++;
       istringstream iss(line);
       iss >> name >> a >> b >> c >> d;
           avg=a+b+c+d; //addition of all temperature
       avg=avg/4; //average
       if(min_ans>avg){min_ans=avg; min_name=name;}
       if(max_ans<avg){max_ans=avg; max_name=name;}
   }
   cout<<"number of cities examined :"<<count<<" ";
   cout<<min_name<<" has the minimum average annual temperature of "<<min_ans<<" ";
   cout<<max_name<<" has the minimum average annual temperature of "<<max_ans<<" ";

}

Output :

G580:~$ g++ temread.cpp
G580:~$ ./a.out
number of cities examined :51
Fairbanks,_Alaska has the minimum average annual temperature of 26.975
Honolulu,_Hawaii has the minimum average annual temperature of 77.4
G580:~$
