A+ Interview Questions & Answers (2025)

• An A+ function may have up to nine formal parameters.
• A+ code statements are separated by semicolons, so a single statement may be divided into two or more physical lines.
• The explicit result of a function or operator is the result of the last statement executed.
• A+ implements an object called a dependency, which is a global variable (the dependent variable) and an associated definition that is like a function with no arguments. Values can be explicitly set and referenced in exactly the same ways as for a global variable, but they can also be set through the associated definition.

In display and print, of course, A+ represents numbers in decimal. People tend to think in decimal and their input is usually decimal. Numbers like .1 and .01 seem exactly representable intrinsically (as they are in decimal), but, in fact, these numbers cannot be exactly represented in binary, and decimal to binary and binary to decimal conversions are one source of imprecision.
