What is quadratic probing in data structure?
Quadratic probing is a scheme in computer programming for resolving collisions in hash tables.
Quadratic probing operates by taking the original hash value and adding successive values of an arbitrary quadratic polynomial to the starting value. This algorithm is used in open-addressed hash tables. Quadratic probing provides good memory caching because it preserves some locality of reference; however, linear probing has greater locality and, thus, better cache performance. Quadratic probing better avoids the clustering problem that can occur with linear probing, although it is not immune.
What is coping with complexity in oops?
The size and complexity of a small program is small and simple. Whereas, the size and complexity of a large application program is large and hard. The complexity in dealing with the problems to build a large application depends on the 'composition' and 'abstraction' mechanisms.
Why it is important to use potholders in holding hot objects?
It is important to use potholders when holding hot objects to prevent burns to the hands.
Is drive F internal or external?
In Windows operating systems, the drive letter (F in this example) is assigned to a logical partition of an internal, external or even virtual device, so it could stand for any of these.

What happens after the packet leaves the router?
After the packet leaves the router, it is sent to the receiving address that is contained in the header in its wrapper. It may not travel the same path as other packets that make up the message, however.
because humans hav sex is thet wot ur talking about well its because humans enjoy sex and primates don't only humans and dolphins do the apes just do it naturally and when ur watchin at the zoo thnx another answer from urs truly skyll kid
What is a geographic information system GIS explain advantage of such system?
A geographic information system differs from other computerized information systems in two major respects. First, the information in this type of system is geographically referenced (geocoded). Second, a geographic information system has considerable capabilities for data analysis and scientific modeling, in addition to the usual data input, storage, retrieval, and output functions.
A geographic information system is composed of software, hardware, and data. The notion of data layer (or coverage) and overlay operation lies at the heart of most software designed for geographic information systems.
two or more processes are reading or writing some shared data and the final result depends on who runs precisely when, are called race condition.
Violations of the strict precise set of rules that define a programminig language are called?
syntax error
What is the sub system in the system analysis and design?
Sub system is basically a module of the system performing a particular task. A big system may be seen as a set of interacting smaller systems known as subsystems or functional units each of which has its defined tasks. All these work in coordination to achieve the overall objective of the system.
What is the relationship between a pathname and a working directory?
The working directory (or working folder) is the default folder (also known as the current folder) used by an application to read and write files when no path name is specified, or a relative path name is specified. Path names may be specific (overriding the default) or relative to the default (navigating up through parent folders and/or down through child folders). A program may also change the default through the "change directory" system command at runtime.
When you write programs you work with data in three different forms?
Variables, Literals, and Named constants.
How do you get your nested loop to decrement and not increment?
Easy. Change any + to -, any += to -=, any ++ to --
COMPILER : It is an "INTERPRETER" which takes the instruction from the user(program/any thing) and converts onto the systems language('0' and '1' binary language) for doing calculations according to that instructions and produces the final output to the user in general english. Annapurna. [stated most simply...] A compiler is a program that takes the program-writers' code, called "Source Code", and forms it into a for the computer understands. That said, there are 'programs', more often called scripts or batch code which is human-readable that the computer can use. While scripting languages can be very powerful, they cannot make full use of a computers' abilities. There are many languages that one can use to create a computer program. C+, C++, COBOL, PASCAL, FORTRAN (some old ones there...) Check out this link for more info. http://www.personal.kent.edu/~rmuhamma/Compilers/compiler.html A compiler is a computer program that translates a computer program written in one computer language (called the source language) into an equivalent program written in another computer language (called the output, object, or target language). A compiler is a computer program (or set of programs) that transforms source code written in a computer language (the source language) into another computer language (the target language, often having a binary form known as object code). The most common reason for wanting to transform source code is to create an executable program.
The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a lower level language (e.g., assembly language or machine code). A program that translates from a low level language to a higher level one is a decompiler. A program that translates between high-level languages is usually called a language translator, source to source translator, or language converter. A language rewriter is usually a program that translates the form of expressions without a change of language.
A compiler is likely to perform many or all of the following operations: lexical analysis, preprocessing, parsing, semantic analysis, code generation, and code optimization.
Program faults caused by incorrect compiler behavior can be very difficult to track down and work around and compiler implementors invest a lot of time ensuring the correctness of their software.
The term compiler-compiler is sometimes used to refer to a parser generator, a tool often used to help create a compiler. A compiler is a software tool that takes raw source code and converts (or compiles) it into a machine language ready for linking and loading. The original sequence is usually called the source code and the output called object code. Commonly the output has a form suitable for processing by other programs (e.g., a linker), but it may be a human-readable text file. A compiler does the translation all at once. It produces a complete machine language program that can then be executed. e.g. Java uses a compiler to translate java programs into Java Bytecode, which is a machine language for the imaginary Java Virtual Machine. Although bytecode is similar to machine language, it is not the machine language of any actual computer. Compiled code does the work much more efficiently, because it produces a complete machine language program, which can then be executed. They can spot syntax errors while the program is being compiled (i.e. you are informed of any grammatical errors before you try to run the program). However, this does not mean that a program that compiles correctly is error-free! ANSWER: compiler is a software tool that converts a high level language into a machine level language.
When a programmer writes code, the code is written in text. If might look like this:
my_variable = get_some_input()
my_other_variable = get_some_input()
sum = my_variable + my_other_variable
put_on_screen(sum)
However, a computer cannot understand text or execute it as a program. What a compiler does it compile the text into bytecode, which is binary data that a computer can execute. Compiled languages are programming languages such as C, C++, Java, VisualBasic, etc., that use a compiler
One can also use an interpreter, which is similar to a compiler, except it translates the text as it is run, rather than beforehand. Interpreted languages, such as Ruby, Python, and Perl, are usually more flexible, but are slower because they are translated to machine language as they are run.
What is comment in c programming?
COMMENT:- comment a re not necessary in the program. however, to understand the flow of programs the programmer can include comments in the program. comment are to be inserted by the programmer. It is useful for documentation.
Comment are nothing but some kind of statements which are placed between the delimiters /* & */. The compiler does not execute comments. Thus, we can say that comments are not the part of executable program.
The user can frequently use any number of comments that can be placed any where in the program. Please note that the comments and statements can be nested. The user should select the OPTION MENU of the editor and select the COMPILER - SOURCE -NESTED COMMENTS ON/OFF). The Comments can be inserted with a single statement or in nested statement.
Types of comment in c/c++. is following bellow
1. // this is a single line comment
2. /* */ this sing is multi line OR nested line comments
eg. /* int i=90;
char ch=65; */ close multi line comments
