Question

The C++ code below will compile but has a variety of runtime issues. Identify a runtime issue with the program and describe how you might fix the problem.

#include <iostream>
#include <vector>

using namespace std;

//------------------------------------------------------------------------------

int main()
{
        vector<double> temps; // temperatures

        double temp = 0;
        double sum = 0;
        double high_temp = 0;
        double low_temp = 0;

        while (cin >> temp)         // read and put into temps
                temps.push_back(temp);

        for (int i = 0; i < temps.size(); ++i)
        {
                if (temps[i] > high_temp)
                        high_temp = temps[i];  // find high

                if (temps[i] < low_temp)
                        low_temp = temps[i];  // find low

                sum += temps[i];      // compute sum
        }

        cout << "High temperature: " << high_temp << endl;
        cout << "Low temperature: " << low_temp << endl;
        cout << "Average temperature: " << sum / temps.size() << endl;
}

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Below are the issues.

• need to break the while loop to take input from the user.
• then need to assign the first element as high_temp and low_temp

Here a new cpp class with name "main.cpp" is created, which contains following code.

main.cpp :

#include <iostream> //header file
#include <vector>
using namespace std;
//main method
int main()
{
vector<double> temps; // temperatures
//declaring variables
double temp = 0;
double sum = 0;
//using while loop reading temperatures
while (temp>=0){ // read and put into temps
cin >> temp;
temps.push_back(temp);//push element in the array
}
temps.pop_back();//removing last element from the array
//assigning first element as high_temp and low_temp
double high_temp = temps[0];
double low_temp = temps[0];
//using for loop checking high_temp and low_temp
for (int i = 0; i < temps.size(); ++i)
{
if (temps[i] > high_temp)
high_temp = temps[i]; // find high

if (temps[i] < low_temp)
low_temp = temps[i]; // find low

sum += temps[i]; // compute sum
}

cout << "High temperature: " << high_temp << endl;//print high temperature
cout << "Low temperature: " << low_temp << endl;//print low temperature
cout << "Average temperature: " << sum / temps.size() << endl;//Average temperature
}

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

Output : Compile and Run main.cpp to get the screen as shown below

Screen 1 :main.cpp

10 20 25 -10 High temperature: 25 Low temperature: 2 Average temperature: 14.25 ...Program finished with exit code 0 Press ENTER to exit console.
