Real Life Example

To demonstrate a practical example of using functions, let's create a program that converts a value from fahrenheit to celsius:

Example

// Function to convert
Fahrenheit to Celsius
float toCelsius(float fahrenheit) {
  return
(5.0 / 9.0) * (fahrenheit - 32.0);
}

int main() {
  // Set a
fahrenheit value
  float f_value = 98.8;

  // Call the
function with the fahrenheit value
  float result =
toCelsius(f_value);

  // Print the fahrenheit value
  cout
<< "Fahrenheit: " << f_value << "\n";

  // Print the result

cout << "Convert Fahrenheit to Celsius: " << result << "\n";

return 0;
}
