Celsius Temperature Table  //write code under void challenge and create function The formula for converting a temperature from Fahrenheit to Celsius is C=59(F−32)C=59(F-32) where F is the Fahrenheit temperature and C is the Celsius temperature. Write a function named celsius that accepts a Fahrenheit temperature as an argument. The function should return the temperature, converted to Celsius. Demonstrate the function by calling it in a loop that displays a table of the Fahrenheit temperatures 0 through 20 and their Celsius equivalents.\ my code below please adust and use chapter 1- 6 terminology //use only chapter 1-6 terminology!! // must validate input using do while loop examle line 98 - 108 // //call functions and follow the challenge instructions //Description: Assignment6 C++ Chapter 6 #include #include #include #include using namespace std; // Function prototypes int menuOption(); double getSales(string divisionName); void findHighest(double salesNE, double salesSE, double salesNW, double salesSW); void Challenge3(); double fallingDistance(int time); void Challenge5(); double celsius(); void Challenge7(); void Challenge9(); void Challenge10(); void Challenge11(); void Challenge18(); void Challenge20(); void Challenge23(); void Challenge24(); // driver function int main() { do { switch (menuOption()) { case 0: exit(1); break; case 3: system("cls"); Challenge3(); break; case 5: system("cls"); Challenge5(); break; case 7: system("cls"); Challenge7(); break; case 9: system("cls"); Challenge9(); break; case 10: system("cls"); Challenge10(); break; case 11: system("cls"); Challenge11(); break; case 18: system("cls"); Challenge18(); break; case 20: system("cls"); Challenge20(); break; case 23: system("cls"); Challenge23(); break; case 24: system("cls"); Challenge24(); break; default: cout << "\t\tERROR - Invalid option.
