Question

Write a program in C++ that gives the temperature of earth at a depth. It must be in C++ and follow the information below:

Problem description
Write a program to take a depth in kilometers inside the earth as input data; calculate and display
the temperature at this depth in both degrees Celsius and degree Fahrenheit. The formulas are:
Celsius temperature at depth in km: celsius = 10 x depth(km) + 20
Convert celsius to fahrenheit: fahrenheit = 1.8 x celcius +32

You should have 4 functions in your program.
1. void print_introduction (){}
// prints out information to tell the user what this program does.
2. double celsius_at_depth (double depth){}
// computes and returns the celsius temperature at a depth measured in kilometers.
3. double celsius_to_fahrenheit (double celsius){}
// converts a Celsius temperature celsius to Fahrenheit.
4. void print_conclusion(double depth){}
// display the conclusion that what is the temperature in both Celsius and Fahrenheit at depth
of the earth

Additional requirement
There is no calculation in main function. The pseudo code steps for main function as follows:
1. print introduction by calling print_introduction function
2. ask user to enter the depth
3. get user’s input
4. print out the conclusion by calling print_conclusion function
5. ask user if he/she wants to continue
6. get user’s input
7. repeat step 2 to step 6 if user picks ‘Y’ or ‘y’
8. Stop program

All the necessary calculations are done in print_conclusion function. celsius_at_depth and
celsius_to_fahrenheit functions are called from print_conclusion function.
There is no calculation in main function. No calling celsius_at_depth or
celsius_to_fahrenheit functions in main function.

The program run must look as follows:

Hello! The program will tell you the temperature of the earth at any depth.
Enter a depth in KM: 10
The temperature of the earth at a depth of 10 KM is 120 in Celsius, and 248 in Fahrenheit.
Would you like to do it again? (Y/N): y
Enter a depth in KM: 20
The temperature of the earth at a depth of 20 KM is 220 in Celsius, and 428 in Fahrenheit.
Would you like to do it again? (Y/N): n
Program ended with exit code: 0

Answer 1

#include <iostream>

using namespace std;

//printing introduction function

void print_introduction(){

    cout<<"Hello! The program will tell you the temperature of the earth at any depth."<<endl;

}

//Temperature calculation function

double celsius_at_depth(double depth){

    return (10*depth)+20;

}

//Converting the celsius to fahrenheit function

double celsius_to_fahrenheit (double celsius){

    return (1.8*celsius) +32;

}

//printing conclusion method that calls the above two methods

void print_conclusion(double depth){

    cout<<"The temperature of the earth at a depth of "<<depth<< " is "<<celsius_at_depth(depth)<<" and "<< celsius_to_fahrenheit(celsius_at_depth(depth))<<" in Fahrenheit."<<endl;

}

int main() {

    //using do while loop to run the program continously

    char ch='y';

    double depth=0;

    do{

        cout<<"Enter a depth in KM: ";

        cin>>depth;

        print_conclusion(depth);

        cout<<"Would you like to do it again? (Y/N): ";

        cin>>ch;

    }while(ch=='y'|| ch=='Y');

    return 0;

}

Output:
