c functions and calls - UGN Security Forum

hello,

please take a look at the following code and give me some feedback on

1. does it reflect "good programming style"
2. is it "portable"
3. is it "elegant"

i am learning this c language and would love feedback.

so far you guys have been a great help. i want to get up to speed on this programming stuff asap. i got a graphlink for my ti - 83+ graphing calc and wanna get into some assembly with it .. but thats a whole other topic ....

so heres the code ...

Code

 
float celsius_conversion(float fahr);
float kelvin_conversion(float celsius);


float fahr, celsius, kelvin;

int main(void)
{
	

	printf ("\nPlease enter the temperature in Farenheit\n");
	printf ("that you wish to convert to Celsius and Kelvin: ");
	scanf (" %f", &fahr);
	celsius = celsius_conversion(fahr);
	printf("\n%.1f Degrees Farenheit is:\n\n1. %.1f Degrees Celsius\n2. %.1f Kelvin",
	fahr, celsius_conversion(fahr), kelvin_conversion(celsius));
	
	return 0;
}

float celsius_conversion(float fahr)
{   
    
	celsius = (5 * (fahr -32)/9);
	
	return celsius;
	
}

float kelvin_conversion(float celsius)
{
	kelvin = celsius + 273.15;
	
	return kelvin;
	
}
