A+ Interview Questions
A+ Programming Interview Questions and Answers
A+ is an array coding language derived from the language A and developers extended it by adding a GUI and other features. A+ is a high-level, interpreted language, designed for numerically intensive applications, particularly those found in financial applications. Moreover, A+ works on many Unix variants, including Linux, and is free and open-source software released under a GNU General Public License. In addition to that, A+ also renders an extended set of functionalities, a GUI with automatic synchronizing of widgets and variables, asynchronous performing of functions associated with variables and events, dynamic loading of user compiled subroutines, and additional features and the newer graphical user interface has not yet been ported to all supported platforms.
Finally, We have listed below the Best A+ Interview Questions and Answers for the best preparation of A+ Interview. These interview questions are very popular & helpful for the preparation of the A+ Interview. apart from this, you can also download below the A+ Interview Questions PDF completely free.
A+ Interview Questions
1) What is A+ programming language?
source:http://www.aplusdev.org/index.html
2) Who Wrote A+?
3) What is APL programming language?
Source: Wikipedia.
4) What were the changes that the A+ language brought about in APL?
- 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.
5) List some features of A+ programming language
- An A+ function may have up to nine formal parameters.
- A+ code statements are separated by semicolons.
- The explicit result of an operator or function is the result of the last statement executed.
- A+ implements an object called a dependency.
6) Explain Nonscalar Primitive Functions
- Informational functions: Shape, Count, Depth, Type;
- Structural functions: Reshape, Interval, Restructure, Reverse, Rotate, Transpose, Transpose Axes, Ravel, Item Ravel, Enclose, Disclose, Rake, Raze, Partition, Take, Drop, Replicate, Expand, Catenate, Laminate;
- Selection functions: Pick, Choose, Bracket Indexing, Right, Left, Null, Separate Symbols;
- Computational functions: Matrix Inverse, Solve, Deal, Pack, Unpack, Encode, Decode;
- Comparison functions: Match, Member, Find, Bins, Grade up, Grade down, Partition Count;
- Format and representation functions: Format, Default Format, Cast;
- Specificational functions: Assignment, Append, Bracket Indexing Selective Assignment, Replace All, Selective Assignment; Beam;
- Evaluative, display, and control functions: Execute, Execute in Context, Protected Execute, Value, Value in Context, Result, Signal, Print, Stop; Time.
7) What type of control statements are used in A+?
8) How numbers are represented in A+?
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.

9) What is the rank operator?
10) List some Scalar Monadic Functions of A+ programming ?
