fahrenheit to celcius

To convert Fahrenheit to Celsius in the C programming language, you can use the following formula:

Celsius = (Fahrenheit - 32) * 5/9

Here's an example code snippet that demonstrates the conversion:

#include <stdio.h>

int main() {
    float fahrenheit, celsius;

    printf("Enter temperature in Fahrenheit: ");
    scanf("%f", &fahrenheit);

    celsius = (fahrenheit - 32) * 5 / 9;

    printf("Temperature in Celsius: %.2f\n", celsius);

    return 0;
}

Let's break down the code and explain each step:

  1. We include the stdio.h header file, which allows us to use the printf and scanf functions for input and output.
  2. In the main function, we declare two variables: fahrenheit and celsius. These variables will hold the temperature values.
  3. We prompt the user to enter the temperature in Fahrenheit using the printf function.
  4. We read the input temperature from the user using the scanf function and store it in the fahrenheit variable.
  5. We apply the conversion formula (Fahrenheit - 32) * 5/9 to calculate the temperature in Celsius and store it in the celsius variable.
  6. Finally, we use the printf function to display the temperature in Celsius with two decimal places.

That's it! The code takes the temperature in Fahrenheit as input, converts it to Celsius using the formula, and then displays the result.
