Question

Programming: Create a class called City with two public variables: a string to store the name of the city and a float to store the average temperature in Fahrenheit.

Create one object of the class that you create and ask the user to enter the city name and the average temperature in Fahrenheit. Store these in the object of the class that you create. Then display the contents of the class.

Once that is working, make the variables private and create four public methods (functions) that get and set each of the values (follow the example in the lecture notes as needed) – these should be called: getName, setName, getTempF, and setTempF. Replace the places where you set and display the variables with these functions as needed.

Add a constructor that initializes the name of the city to San Jose and the average temperature to 75. Show that this works by displaying the contents of your object before asking the user for any input.

Finally, add one more function called getTempC that calculates the temperature in Celsius and returns that. Add a function call that gets piped to cout to display the temperature of your city in Celsius.

Dear Student ,

As per requirement submitted above kindly find below solution.

Here new cpp program with name "main.cpp" is created which contains below code.

main.cpp :

//header files
#include <iostream>
using namespace std;
class City{ //cpp class
string city;//private variables
float tempF;
public:
City()//constructor
{
city="San Jose";
tempF=75;
}
string getName(){return city;}
void setName(string nm){city=nm;}
float getTempF(){return tempF;}
void setTempF(float temp){tempF=temp;}
float getTempC(){
//return temprature in celisus
return (getTempF()-32)*5/9;
}
};

//main() method
int main()
{
//declaring variables
string name;
float temp;
//object of City
City c;
//asking user to enter city name
cout<<"Enter city name : ";
cin>>name;//reading city
c.setName(name);//set name
//asking user to enter temprature
cout<<"Enter Temprature in Fahrenheit : ";
cin>>temp;//reading temprature
c.setTempF(temp);//set temprature
//print details
cout<<"City :"<<c.getName()<<endl;
cout<<"Temprature in Fahrenheit :"<<c.getTempF()<<endl;
cout<<"Temprature in celisus : "<<c.getTempC()<<endl;
return 0;
}

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

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