Using the CelsiusToKelvin function as a guide, create a new function, changing the name to KelvinToCelsius, and modifying the function accordingly.

#include

double CelsiusToKelvin (double valueCelsius) {

double valueKelvin = 0.0;

valueKelvin = valueCelsius + 273.15;

return valueKelvin;

}

int main (void) {

double valueC = 0.0;

double valueK = 0.0;

valueC = 10.0;

printf ("%lf C is %lf K/n", valueC, CelsiusToKelvin (valueC));

valueK = 283.15;

printf ("%lf is %lf C/n", valueK, KelvinToCelsius (valueK));

return 0;

}

The function modification to this question can be given as follows:

Modification Function:

double KelvinToCelsius (double valueKelvin) / /defining method KelvinToCelsius

{

double valueCelsius = valueKelvin - 273.15; / /defining variable valueCelsius and calculate value

return valueCelsius; / /return value

}

The whole program to this question as follows:

Program:

#include / /include header file to use basic functions

double CelsiusToKelvin (double valueCelsius) / /defining method CelsiusToKelvin

{

double valueKelvin = 0.0; / /defining variable and assign a value

valueKelvin = valueCelsius + 273.15; / /calculate value

return valueKelvin; / /return value

}

double KelvinToCelsius (double valueKelvin) / /defining method KelvinToCelsius

{

double valueCelsius = valueKelvin - 273.15; / /defining variable valueCelsius and calculate value

return valueCelsius; / /return value

}

int main () / /defining main method

{

double valueC = 0.0, valueK = 0.0; / /defining variable valueC and valueK assign value

valueC = 10.0; / /change variable value

printf ("%lf C is %lf K/n", valueC, CelsiusToKelvin (valueC));

valueK = 283.15; / /change variable value

printf ("%lf is %lf C/n", valueK, KelvinToCelsius (valueK));

return 0;

}

Output:

10.000000 C is 283.150000 K

283.150000 is 10.000000 C

Explanation:

In the above modification function, a function "KelvinToCelsius" is defined, which accepts double variable "valueKelvin" as a parameter, and the function returns a value, which is double type. Inside a function, another double variable valueCelsius is defined, which minus 273.15 from parameter value and, store this value in valueCelsius variable.
