在c编程中使用函数的温度转换器

double celsius_to_fahrenheit(double celsius) {
    double fahrenheit = (celsius * 9 / 5) + 32;
    return fahrenheit;
}

double fahrenheit_to_celsius(double fahrenheit) {
    double celsius = (fahrenheit - 32) * 5 / 9;
    return celsius;
}

#include <stdio.h>

double celsius_to_fahrenheit(double celsius);
double fahrenheit_to_celsius(double fahrenheit);

int main() {
    double celsius = 25;
    double fahrenheit = celsius_to_fahrenheit(celsius);
    printf("%.2f degrees Celsius is equal to %.2f degrees Fahrenheit\n", celsius, fahrenheit);

    double temperature = 77;
    double converted_temperature = fahrenheit_to_celsius(temperature);
    printf("%.2f degrees Fahrenheit is equal to %.2f degrees Celsius\n", temperature, converted_temperature);

    return 0;
}

double celsius_to_fahrenheit(double celsius) {
    double fahrenheit = (celsius * 9 / 5) + 32;
    return fahrenheit;
}

double fahrenheit_to_celsius(double fahrenheit) {
    double celsius = (fahrenheit - 32) * 5 / 9;
    return celsius;
}
