I'm working through a practice problem and am wondering
if there's a more efficient way of writing my code and/or if the syntax for my pointers looks correct.

The practice problem:

• Given the absolute temperatures Tc of a cold reservoir and Th of a hot reservoir (in degrees Kelvin), the coefficients of performance (cp) of the refrigeration cycle and heat pump are given by:
  
  
  • Refrig: cp = Tc / (Th - Tc)
  
  
  • Heat: cp = Th / (Th - Tc)
  
  


• Write a program that will call a function to prompt the user for the values of Tc and Th . It then calls a function that calculates the two coefficients of performance. Finally, it calls a function to print the results.

Here is what I have:

#include <stdio.h>

void temperature(float *, float *);
void performance(float,float,float *, float *);
void PrintResults(float,float,float,float);

int main()

 float Tc, //cold reservoir; user input
 Th, //hot reservoir; user input
 Rcp, //refrigeration cycle coefficient of performance
 Hcp; // Heat pump coefficient of performance

 temperature(&Tc,&Th); //Prompts user for cold & hot reservoir temperatures
 performance(Tc,Th,&Rcp,&Hcp); //Calculates the coefficients of performance
 PrintResults(Tc,Th,Rcp,Hcp); //Prints the coefficients of performance
 return 0;

void temperature(float *ptrTc, float *ptrTh)

 printf("Enter the absolute temperature for a cold reservoir (in Kelvin): ");
 scanf("%f",&*ptrTc);
 printf("Enter the absolute temperature for a hot reservoir (in Kelvin): ");
 scanf("%f",&*ptrTh);

void performance(float Tc, float Th, float *ptrRcp, float *ptrHcp)

 *ptrRcp = Tc/(Th-Tc);
 *ptrHcp = Th/(Th-Tc);

void PrintResults(float Tc, float Th, float Rcp, float Hcp)

 printf("nGiven the absolute temperatures of %.2f K for the cold reservoir",Tc);
 printf(" and %.2f K for the hot reservoir,",Th);
 printf(" the coefficient of performance for the refrigeration cycle is %.2f K",Rcp);
 printf(" and the coefficient of performance for the heat pump is %.2f Kn",Hcp);
