1. Physicists tell us that the lowest possible temperature is absolute zero. Absolute zero is -459.69 degrees Fahrenheit.

a. Accept inputs from the user: a beginning temperature, an ending temperature, and an increment value (all Fahrenheit).

b. Check for bad input: a temperature less than absolute zero and an ending temperature less than a beginning temperature. The program will send a message to STDERR if either condition is detected.

#### Solution Preview

Following is the Temperature program.
chomp simply removes the newline character from the string.
The first if statement checks if \$end is less than \$beg and the second if statement checks
if either of them is less than the Absolute Zero temperature.
Remember, we are dealing with negative numbers and -1 is greater than -2!
Also, ...

#### Solution Summary

The solution is a working PERL code.
