Question

This is a C++ program that runs properly.
I need to know the details of every code line such as what each line does. For example what they are (declarations, assignments, expressions, selection, repetition etc. , objects that are being used, and the types that are being used such as int, double, string) I want to be able to understand the program. I can run it but I dont know exactly the point of the code functions etc. Please be as detailed as possible. Thank you

Explanation / Answer

here i have written the comments..

================================================================

//these are the headers files which has the defintions of each and every function used in our program.

1 #include<iostream>
2 #include<vector>

//statndard namespace
3 using namespace std;
4

//start of main function
5 int main(){
6

       //a vector v is declared of double type
7 vector<double>v;

        //variabls are declared whcih will be used in the program
8 double average, min, max, input, sum, i, c_temp;

       //ask the user to input temperatures
9 cout << "Enter Fahrenheit temperatures (press Ctrl-Z to finish): ";
10

         //while input is received by user
11 while (cin >> input)

              //store the number to vector
12 v.push_back(input);

            //initialize sum to 0.0
13 sum = 0.0;

         //this for loop will iterate each element and calculate the sum
14 for (size_t i=0; i<v.size(); i++)
15 sum += v[i];

             //here calculation of average has been done
16 average = sum/v.size();

         //this for loop is used to calculate the max and min element in the vector
17 for (i=0 ; i<v.size(); i++)

         {

           //if v[i] is greater than max then update the value of max
18 if (v[i] > max)
19 max = v[i];

      //if v[i] is less than max then update the value of min

20 else if (v[i] < min)
21 min = v[i];
22 }

         //here we have displayed the average, min, max etc
23 cout << "The average in degrees Fahrenheit is: " << average << endl;
24 cout << "The minimum temperature in degrees Fahrenheit is: " << min << endl;
25 cout << "The maximum temperature in degrees Fahrenheit is: " << max << endl;
26 cout << "The average in degrees Celsius is: " << (average -32) * (5.0/9.0) << endl;
27 cout << "The minimum temperature in degrees Celsius is: " << (min-32) * (5.0/9.0) << endl;
28 cout << "The maximum temperature in degrees Celsius is: " << (max-32) * (5.0/9.0) << endl;
29
30 return 0;
31 }
