Common Programming Errors
 Values for constants or variables out of range. Table A-1 lists accept-
able ranges for variables and constants.
 Mismatched types. For example, the literal constant 3293 is of type
int (16-bit integer). However, the literal constant 3293.0 is of type
float. Although Dynamic C can handle some type mismatches,
avoiding type mismatches is the best practice.
 Counting up from, or down to, one instead of zero. In software, ordinal
series often begin or terminate with zero, not one.
 Confusing a functions definition with an instance of its use in a listing.
 Not ending statements with semicolons.
 Not inserting commas as required in functions parameter lists.
 Leaving out ASCII space character between characters forming a
different legal, but unwanted operator.
 Confusing similar-looking operators such as && with &,
== with =, and // with /.
 Inadvertently inserting ASCII nonprinting characters into a source-code
file.
