The following program is taken verbatium from THE C PROGRAMMING
LANGUAGE, by Brian W. Kernigan and Dennis M. Ritchie.
/* print Fahrenheit-Celsius table
* for f = 0, 20,..., 300
*/
main()
{
int lower, upper, step;
double fahr, celsius;
lower = 0; /* lower limit of temperature table */
upper = 300; /* upper limit */
step = 20; /* step size */
fahr = lower;
while (fahr <= upper) {
celsius = (5.0/9.0) * (fahr-32.0);
printf("%4.0f %6.1f\n", fahr, celsius);
fahr = fahr + step;
}
}
Can anyone tell me why this will not compile under PRODOS
HyperC?

I'm not sure about hyperC but maybe you have forgotten to #include <stdio.h> exactly what error does it give you?

It does if you use the floating point libraries, as described in the file READ.ME

Doubles are fp and if a compiler/linker supports them at all you generally have to use special libraries etc. For the sake of experimentation change the doubles to int and change the numbers containing decimal places to integers. The results won't be correct but this will help narrow down the problem. ******************************************************************** * * * bob church bchurch@oucsace.cs.ohiou.edu * * * * If economics isn't an "exact" science why do computers crash * * so much more often than the stock market? * * bc * ********************************************************************

Yes, i did included the fp.h Any clue?

If you want to do math with them or print them out, you must use the stuff on the /FP/ disk (see the file README). The floating point stuff does work, but since it's all done with functions, it's really icky. I can post a working floating point program if people want to see an example. -- Doug Reeder USENET: ...!tektronix!reed!reeder from ARPA: tektronix!reed!reeder@berkeley.EDU BITNET: reeder@reed.BITNET the Little Mermaid on materialism: I just don't see how a world that makes such wonderful things ... could be bad!

So %f and 5.0, etc. don't make the compiler happy. They were developing a floating point extension when they went under, but I have heard that it was "completed" and have heard reports on its availability.
