Computer Programming

J2EE = enterprise edition jdk. J2SE = standard edition jdk. J2ME = mobile edition jdk. standard jdk gets used for platform development, enterprise jdk for enterprise development and mobile jdk gets used for mobile development.

Being a computer scientist is a well paying job. They make on average $5000 to $8000 per month. And job prospective are very good.

The main differences between an array and a structure are:

An Array is a collection of similar data items.An array is derived data type.It behave like a built in data type. An array can be increased or decreased.

A structure is a collection of dissimilar data items.It is a user defined data types.It must be declared and defined.A structure element can be added if necessary.

A first generation contact language is called a pigdin. The feature of human language that allows people to talk about the past and the future is referred to as displacement.

Mainly JavaSript is a low-level scripting language that differs from the high-level languages in its easiness. The core language is really simple, and is designed to be easier for beginners,

I.e. JS i loosly typed. Meaning that a variable can reference any kind of literal, array or object, which differs from the high-level C-languages where you have to declare if a variable i to reference an integer, floating-point, string, hash-map and so on.

Another major difference is that JS, like python or php isn't compiled to machine code, but interpreted at runtime, making programs run significantly slower than compiled programs.

Another difference which is good, and unique to JS is that it does not inherit the C class model when working in OOP. Objects in JavaScripts can be crated and altered as one want to, beeing more dynamic to work with. A classical model can however be adopted with use of functions and use of the 'new' keyword. Here the lack of private variables can be worked around by the use of a technique called 'closure'.

The major difference however is that programs written in JS to work with the HTML DOM tend to not follow the normal procedural 'step-by-step' executions as conventional programs, where one line of code is being executed at the time. In stead JS tend to follow a Event Loop model, where different parts of the programs are attached to different DOM events. The JS-program will then sleep until a event is fired, then wake up, do its job, then go back to sleep. And so on. All in all making JS a very dynamic and "fun to work with" language.

A compiler and a linker.

an auxiliary verb that expresses necessity or possibility. English modal verbs include must, shall, will, should, would, can, could, may, and might.

It's easy: there are no commands in C, but a few statements (such as: expression, if, else, switch, while, do-while, for, break, continue, return and goto), and countless library functions (like printf, malloc and fopen).

Bubble sort-O(n*n)-in all cases

Insertion sort-O(n*n)-in avg and worst case in best case it is O(logn)

Quick Sort-0(nlogn)-in avg n best case and 0(n*n)-in Worst case

selection sort-same as bubble

Linear search-o(n)

Binary Search-o(nlog)

Having an unsigned integer means that the integer is positive, and not negative; literally, the integer is unsigned and assumed to be positive. The unsigned integer 8 is positive-eight, not negative-eight.

The latter isn't primitive. Most likely it means 'non trivial', 'adaptive' or 'sophisticated'.

An aspect-oriented programming language is another name for an aspect-oriented language - a computer programming language which aims to increase modularity by allowing the separation of crosscutting concerns.

You don't. Queues are a first in, first out structure, specifically used to process incoming data in the same order it arrives. If you want to sort a data sequence then use an array or a list.

Depends on your language. Assuming java: If you make it an Object[] then it can contain any object

For primitive types you must either make a primitive type array, ie double[], char[] which can contain only those primitives, or creater an Object[] and use primitive wrapper objects ie java.lang.Integer etc.

1. An array is a variable containing multiple values. Any variable may be used as an array. There is no maximum limit to the size of an array, nor any requirement that member variables be indexed or assigned contiguously. Arrays are zero-based: the first element is indexed with the number 0.

Ideally, never. Friend functions should only be employed when a function (whether an operator overload or not) requires private access to a class, and it is not otherwise possible to provide a public interface without unduly undermining the class encapsulation. However, as programmer, it is your responsibility to ensure all friend functions adhere to the same class rules (which you yourself define) as do the members of your class, even though friends are not regarded as being members of the class. Ultimately, if you have no control over the friend function implementation, then you must not allow that function to be a friend of your class, as this will seriously undermine the encapsulation.

in java buffering is used for handling i/o streamswhen you use an unbuffered stream the data is directly transferred from the source to whatever.when you use buffered stream the data is taken from the source and placed into something like a holding area. then the information can be taken from this holding area at will which makes buffered streams more efficient.for example when you load a vid on youtube once part of it loads you can use play anypart of the loaded vid. that's not exactly how it works but it gives you a general sense.

Advantages of OOP Object-Oriented Programming has the following advantages over conventional approaches: * OOP provides a clear modular structure for programs which makes it good for defining abstract datatypes where implementation details are hidden and the unit has a clearly defined interface. * OOP makes it easy to maintain and modify existing code as new objects can be created with small differences to existing ones. * OOP provides a good framework for code libraries where supplied software components can be easily adapted and modified by the programmer. This is particularly useful for developing graphical user interfaces. Let's distinguish two sorts of disadvantages: * OO is often provided through such imperfect vehicles as C++ and Java [discuss their defects]; and * OO is inapplicable because [explain many mismatches

"What are difference between Prim's algorithm and Kruskal's algorithm for finding the minimum spanning tree of a graph?"

Prim's method starts with one vertex of a graph as your tree, and adds the smallest edge that grows your tree by one more vertex. Kruskal starts with all of the vertices of a graph as a forest, and adds the smallest edge that joins two trees in the forest. Prim's method is better when * You can only concentrate on one tree at a time * You can concentrate on only a few edges at a time

Kruskal's method is better when * You can look at all of the edges at once * You can hold all of the vertices at once * You can hold a forest, not just one tree

Basically, Kruskal's method is more time-saving (you can order the edges by weight and burn through them fast), while Prim's method is more space-saving (you only hold one tree, and only look at edges that connect to vertices in your tree).
