Thread: Temperature Conversion code problems

I cannot seem to get the program to work correctly. I have tried to figure out whats wrong with the code but i got nothing, i am new to C programming any help will be much appreciated.

thanks a bunch!

Code:

#include <stdio.h>

void main()
{
	float (temp_kelvin);
	float (temp_celcius);
	float (temp_farhenheit);
	printf("Enter a temperature in Celcius:");
	scanf_s("2f",&temp_celcius);
		temp_kelvin = (temp_celcius + 273.15);
	    temp_farhenheit = (((1.8)*temp_celcius)+32);
		
	printf("The equivalent Farhenheit temperature is: .2%f\n", temp_farhenheit);
	printf("The equivalent Kelvin temperature is: .2%f\n", temp_kelvin);
}

Fix those. And not that it's a problem, but I don't see a reason to put variable names in parentheses.

Code:

#include <stdio.h>


void main()
{
	float temp_kelvin;
	float temp_celcius;
	float temp_farhenheit;
	printf("Enter a temperature in Celcius: ");
	scanf_s("2f",&temp_celcius);
		temp_kelvin = (temp_celcius + 273.15f);
	    temp_farhenheit = ( ( (1.8) * temp_celcius) + 32);
		
	printf("The equivalent Farhenheit temperature is: .2%f\n", temp_farhenheit);
	printf("The equivalent Kelvin temperature is: .2%f\n", temp_kelvin);
}

thats what i got now and still not work. it gives the same incorrect temperatures no matter what starting celcius temperature i use. this is leading me to believe there is an error in the

Code:

scanf_s("2f",&temp_celcius);

line possibly?

You also forgot about these:

temp_farhenheit = (((1.8f) * temp_celcius) + 32.0f)
new.c:3:6: Function main declared to return void, should return int
