Not really. Officially, there is no such thing as a fourth-generation language (4GL). The term 3GL first appeared after the third-generation of hardware first appeared and applied to all high-level languages, including PROLOG. Today we do not use terms such as 4GL or 5GL as they are just meaningless buzzwords coined by marketing types. Today, all high-level languages are classified according to whether they are imperative, declarative, functional, object-oriented, and so on. PROLOG, in its un-extended form, is an example of a declarative language.

A two-dimensional array is the simplest multi-dimensional array and is implemented as a one-dimensional array where every element is itself a one-dimensional array. We can imagine a two-dimensional array as being a table of rows and columns where every row is an array in its own right.

A three-dimensional array is simply a one-dimensional array of two-dimensional arrays, which can be imagined as being an array of tables. Extending the concept, a four-dimensional array is a table of tables.

Multi-dimensional arrays may be jagged. That is, a two-dimensional array may have rows of unequal length. Unlike regular arrays, jagged arrays cannot be allocated in contiguous memory. Instead, we use the outer array (the first dimension) to store pointers to the inner arrays. An array of strings (character arrays) is an example of a two-dimensional jagged array.

Software. Anything that is not hardware (a physical device) is software. This includes both the programs and data used by those programs.

The answer lies in difference in Object oriented and variable based technology. Object oriented technology has a lot of benefits. One of which is that it eliminates declaration of variables for every time usage. It means that disk space is saved as variables are declared only once and only object is created further which gets an instance of these variables. It makes logic to easy implement and understand. Its systematic way of implementing a problem statement.

String hello = "hello";

for(int i = 0; i < hello.length(); i++){

System.out.print(hello.substring(0,i+1));

}

/*

* This loop will loop over the string "hello". For each loop it will print

* the entire string from the beginning to the index of i. Therefore, the

* first loop will print hello.substring(0,1), or "h". The next loop will

* print hello.substring(0,2) or "he". These are all printed together so

* it becomes "hhehelhellhello"

*/

Here are some of the first we know of:

* Babylonians, 1600 BC - factorization and square roots
* Euclid, 300 BC - greatest common divisor (GCD)
* Eratosthenes, 200 BC - prime numbers
* Liu Hui, 263 AD - systems of linear equations

Smalltalk was the language created as a proof-of-concept implementation of the object-oriented programming paradigm.

1. effectiveness of the system if whether it achieves its goals or not.
2. efficiency , check if what is produced is it the product that was supposed to be produced.
3. complexity ,checking on how the system elements are complicated .
4. control ,operate under the given instruction.

Some of the common examples of scientific software include those used to predict weather, those used in prediction of genome structure, etc.

Basically scientific software's are those that are used to perform some rigorous calculations which help in understanding some physical process.

In general using malloc is faster, since calloc initializes the allocated memory to contain all zeroes. If this is what you want, however, then calloc can be used. The results can vary among different operating systems and environments, though. Memory allocation in an OS that uses floating blocks in heaps, such as Microsoft Windows and MacOS, should use the OS-native memory allocators instead. "Use malloc() almost always and calloc() almost never." The reason is that the initialization to zero that calloc() performs is usually not very helpful: - The initialization to "all-bits-zero" is not necessarily the same as initialization to "all-data-zero." C says very little about the representation of values in memory, nothing at all for floating-point or pointer values. On many machines all-bits-zero representations will in fact correspond to f.p. zeroes or null pointers, but this is not guaranteed by the language and there have been machines where the correspondence did not hold. If you get in the habit of using calloc() to initialize f.p. and pointer items, you may be heading for trouble. - Usually, one allocates a chunk of dynamic memory in order to store something in it -- and when you store something in it, you'll overwrite whatever was there before. Thus, the initialization performed by calloc() is usually not needed anyhow. There are occasional exceptions where all- bits-zero initialization is helpful, but they are unusual.

Yes. It is possible to provide a solution to the diamond-square algorithm using Java and recursion.

In early computing days, computers were expensive, and so to absorb the cost, a big computer would be shared across many people who would pay for time-sharing (such as one hour units). The limiting factor, money, would be the only reason why someone might use a time-sharing system. For that individual, their use of a computer is so infrequent that they cannot justify purchasing an actual computer, or their current hardware is inadequate for their needs, so they lease time on a more powerful system to play games, process data, etc.

Time sharing is most frequently found today in terms of "virtual machines", such as virtual servers or virtual desktops that are accessed remotely through a less powerful system or even a thin client (a keyboard, mouse, and monitor connected to a very small computer with only enough RAM and CPU power to access the remote desktop). It is projected that as computer networking and virtualization becomes more powerful, time-sharing will soon replace or heavily supplement PCs and single-user workstations.

The Method To Add an element in Circular Queue

# define MAXQUEUE 100 struct queue{

int items[MAXQUEUE];

int front, rear;

}

struct queue q;

q.front=q.rear=MAXQUEUE -1;

void ENQ(struct queue *pq, int x)

{

/* make room for new element*/

if(pq ->rear = MAXQUEUE - 1)

pq-> rear = 0;

else

(pq->rear)++;

/* check for overflow */

if(pq ->rear==pq->front)

{

printf("queue overflow);

exit(1);

}

pq->items[pq->rear]=x;

return;

}/* end of ENQ*/

A Method to Delete an element from Circular Queue

int DQ(struct queue *pq)

{

if(pq-> rear == pq-> front)

{

printf("queue underflow");

}/*end if*/

if(pq->front = = MAXQUEUE-1)

pq->front=0;

else

(pq->front)++;

return(pq->items[pq->front]);

The way you stated your question is rather confusing, but what I think you're asking is, "are programs written in high level languages called compiled programs?"

Well, not all high level languages are compiled. Python, for example, is interpreted, instead of compiled. Many, such as C++ (although that is more medium level) are compiled. In general, one would not call a program written in a compiled language a "compiled program" until it's been compiled.

This sounds very much like a homework problem. If you work on it and get started, you found a great place to ask a specific question. However, this is not a place to have your homework done for you.

A Loop is a programming language construct that instructs the processor to repeat a sequence of operations a number of times until a specific condition is reached. There are different types of loops. They are: * for loop * while loop * do while loop

public static void main(String[] args) { int count = 0; int sum = 0; for(int i = 100; i < 200; i++) { if(i%7 == 0){ System.out.println(i); count++; sum = sum + i; } } System.out.println("Number of values divisble by 7 is: " + count); System.out.println("Sum of the values divisible by 7 is: " + sum); }
