#include <iostream.h>

float fToC(float degreesF = 32.0);

int main (void)
{
float fToC(float degreesF)
{
float degreesC = ((5.0/9.0)*(degreesF - 32.0));
return degreesC;
}
float fahrenheit, centigrade;

cout << "Enter a Fahrenheit temperature:\t";
cin >> fahrenheit;
centigrade = fToC(fahrenheit);
cout << fahrenheit << "F is" << centigrade << "C" << endl
cout << "Freezing point: " << fToC() << "C";

return 0;
}

This is the error log
