# C++ Exercises: Convert temperature in Fahrenheit to Celsius

## C++ Basic: Exercise-21 with Solution

Write a C++ program to convert temperature in Fahrenheit to Celsius.

Sample Solution:

C++ Code :

``````#include <iostream> // Including the input-output stream header file

using namespace std; // Using the standard namespace

int main() // Start of the main function
{
float frh, cel; // Declaring floating-point variables for Fahrenheit and Celsius temperatures

cout << "\n\n Convert temperature in Fahrenheit to Celsius :\n"; // Outputting a message indicating temperature conversion
cout << "---------------------------------------------------\n"; // Outputting a separator line

cout << " Input the temperature in Fahrenheit : "; // Prompting the user to input the temperature in Fahrenheit
cin >> frh; // Taking input for the Fahrenheit temperature from the user

cel = ((frh * 5.0) - (5.0 * 32)) / 9; // Converting Fahrenheit to Celsius using the formula: (Fahrenheit - 32) * 5/9

cout << " The temperature in Fahrenheit : " << frh << endl; // Displaying the input temperature in Fahrenheit
cout << " The temperature in Celsius : " << cel << endl; // Displaying the converted temperature in Celsius
cout << endl; // Outputting a blank line for better readability

return 0; // Returning 0 to indicate successful program execution
} // End of the main function
``````

Sample Output:

``` Convert temperature in Fahrenheit to Celsius :
---------------------------------------------------
Input the temperature in Fahrenheit : 95
The temperature in Fahrenheit : 95
The temperature in Celsius : 35
```
