#include<iostream>

using namespace std;

int main()

{

float fahr, cel;

char option;

cout << "Choose from following option:" << endl;

cout << "1. Celsius to Fahrenheit." << endl;

cout << "2. Fahrenheit to Celsius." << endl;

cin >> option;

//option for converting celsius into fahernheit

if (option == '1')

{

cout << "Enter the temperature in Celsius: ";

cin >> cel;

fahr = (1.8 * cel) + 32.0; //temperature conversion formula

cout << "\nTemperature in degree Fahrenheit: " << fahr << " F" << endl;

}

//option for converting Fahrenheit into Celsius

else if (option == '2')

{

cout << "Enter the temperature in Fahrenheit: ";

cin >> fahr;

cel = (fahr - 32) / 1.8; //temperature conversion formula

cout << "\nTemperature in degree Celsius: " << cel << " C" << endl;

}

else

cout << "Error Wrong Input." << endl;

return 0;
