My temperature conversion program in C keeps outputting 0 when I attempt to convert Fahrenheit to Celsius. The conversion from Celsius to Fahrenheit seems to work just fine. I have done the exact same thing for both functions and portions but I keep getting 0 for the second conversion. Can someone please help me or tell me what I am doing wrong?
#include <stdio.h>
//Function Declarations
float get_Celsius (float* Celsius);       //Gets the Celsius value to be converted.
void to_Fahrenheit (float cel);           //Converts the Celsius value to Fahrenheit and prints   the new value.
float get_Fahrenheit (float* Fahrenheit); //Gets the Fahrenheit value to be converted.
void to_Celsius (float fah);              //Converts the Fahrenheit value to Celsius and prints the new value.
int main (void)
{
   //Local Declarations
   float Fahrenheit;
   float Celsius;
   float a;
   float b;
   //Statements
   printf("Please enter a temperature value in Celsius to be converted to Fahrenheit:\n");
   a = get_Celsius(&Celsius);
   to_Fahrenheit(a);
   printf("Please enter a temperature value in Fahrenheit to be converted to Celsius:\n");
   b = get_Fahrenheit(&Fahrenheit);
   to_Celsius(b);
   return 0;
} //main
float get_Celsius (float* Celsius)
{
   //Statements
   scanf("%f", &*Celsius);
   return *Celsius;
}
void to_Fahrenheit (float cel)
{
   //Local Declarations
   float fah;
   //Statements
   fah = ((cel*9)/5) + 32;
   printf("The temperature in Fahrenheit is: %f\n", fah);
   return;
}
float get_Fahrenheit (float* Fahrenheit)
{
   //Statements
   scanf("%f", &*Fahrenheit);
   return *Fahrenheit;
}
void to_Celsius (float fah)
{
   //Local Declarations
   float cel;
   //Statements
   cel = (fah-32) * (5/9);
   printf("The temperature in Celsius is: %f\n", cel);
   return;
}
