#include 

// Function to convert Fahrenheit to Celsius
float fahrenheit_to_celsius(float fahrenheit) {
    return (fahrenheit - 32) * 5 / 9;
}

int main() {
    float fahrenheit;
    printf("Enter the temperature in Fahrenheit: ");
    scanf("%f", &fahrenheit);

    float celsius = fahrenheit_to_celsius(fahrenheit);
    printf("%.2f degrees Fahrenheit is equal to %.2f degrees Celsius.\n", fahrenheit, celsius);

    return 0;
}

The fahrenheit_to_celsius function takes the temperature in Fahrenheit as input and returns the equivalent temperature in Celsius using the formula: Celsius = (Fahrenheit - 32) * 5 / 9. In the main function, the user is asked to input the temperature in Fahrenheit, and the fahrenheit_to_celsius function is called to convert and print the equivalent temperature in Celsius.
