Write a program totake a depth (in kilometers) inside the earth as input data; compute
and display thetemperature at this depth in degrees celsius and degreesfahrenheit.
the relevant formulasare
celsius = 10 (depth) +20 (celsius temperature at depth in km)
fahrenheit = 1.8 (celsius)+ 32
include two functionsin your program. function celsius_at_depth should
compute and return thecelsius temperature at a depth measure in kilometers.
function fahrenheit should convert a celsius temperature tofahrenheit.

#include<iostream>

using namespace std;

//define function to calculate the temperature in Celsius

float celsius_at_depth(float depth){

   float celsius = 10 * (depth) + 20;  //formula for calculation

   return celsius;

}

//define function to calculate the temperature in Fahrenheit

float fahrenheit(float celsius){

   float fahrenheit = 1.8 * (celsius)+ 32;//formula for calculation

   return fahrenheit;

}

//main function program start from here

int main(){

   //initialization

   float depth;

   print message

   cout<<"Please enter the depth (in kilometers): ";

   cin>>depth;

   float cel = celsius_at_depth(depth);  //Calling the function

   float feh = fahrenheit(cel);      //Calling the function

   //print the outputs

   cout<<"The Celsius temperature at depth in km: "<<cel<<endl;

   cout<<"The temperature in Fahrenheit is: "<<feh<<endl;

}

Explanation:

Create function celsius_at_depth with return type float and a parameter. This function takes the value depth from the calling function and calculate the temperature in Celsius and then returns the result to the calling function.

create the second function Fahrenheit with return type float and with one parameter. This function takes the temperature input in Celsius and convert into Fahrenheit and then return to the calling function.

Create the main function and declare the variable.

print the message for the user and store the value enter by the user by using the instruction cin.

then, calling the function and store the return outputs.

Finally, print the output.
