Computer Programming

A computer algorithm is any set of instructions that a computer could use to produce a result. An example would be "given a numeric input, multiply that value by 9, divide the result by 5, then add 32." This is how a Celsius temperature is converted into Fahrenheit.

Arrays takes consecutive memory space.

So, if you have 5 consecutive memory blocks free which is consecutive, an error will

occur while creating an array which takes more than 5 blocks of memory.

But if you use pointer, then it don't need consecutive memory blocks all the elements can be placed anywhere in memory.

it depends on what type of disk if it is a 3.5 inch floppy then there is a tab on the corners that can be moved up or down. if you can see through it , it is write protected if not it can be used.

Almost any language can be used to develop a compiler. The first compilers were written in assembly language or machine code but today they are typically written in C or (more commonly) C++. Other languages can be used, however the key aspects of any compiler are speed and efficiency, in which both C and C++ excel.

programming languages B and BCPL which was used to derive C

string[] str= new string[2]{"ss","gg"}

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

{

Response.wrirte(str[i]);

}

Is called machine code

circular linked list is type of linked list used in data structure where address of 1st node is stored in the link part of last node

data1link1 ................... datanlinkn

address1 here linkn=adress1

(node1) (noden)

Sometimes yes, sometimes no. Many hackers use pre-scripted tools and have no real understanding of how they work. The hackers who write the tools of course have a pretty good understanding of how viruses work.

You insert data into a file by copying the file to a temporary file up to the point of insertion, then copying the data to be inserted, then copying the balance of the original file. After closing the temporary file you delete the original file and rename the temporary file back to the original file's name.

Every programming language has rules that specify how to write instructions. Many programming languages are similar, but mostly they all have different styles and ways of writing the same instructions. This is called the syntax.

The Microsoft Windows series of operating systems could be considered the most used computer program as well as Microsoft Office and Microsoft Internet Explorer. While these programs are not "popular," they are the ones used most often by the greatest number of people.

(One contributor notes that an operating system is not a computer program in the sense that the asker probably intended.)

Pointers to far objects are stored using four bytes (32 bits). The bytes are stored little endian or low to high order. The first word contains the 14-bit memory offset (bits 14 and 15 are always 0). The second word contains the page number (or segment number for function pointers). The memory address is calculated as follows: Variable Address = (Page * 0x4000L) + OffsetFunction Address = (Segment * 0x10000L) + Offset

Binary bits. This is 0s and 1s. Everything else is built up from these 0s and 1s to make more human-understandable language.

0s and 1s are used because it is very easy to make clear, definable electrical signals for 0 and 1. It is simply "on" and "off".

A shell program is a program that runs from the computer's command line. Although they were more common in older programs, some people still use them, as the are generally faster and and more minimalist than their graphical counterparts.

best example is trains...where each coach is connected to next coach except the engine and the last coach..when we need to add a coach we need to move to the right position and adjust the connecting point suitably!!

see where the characters, action, setting, and interpretation all meet.

That depends on the type of engineer. To a hardware engineer I suppose a programmer is just the person that handles software. Hardware engineers don't write code.

A software engineer would either design the program for the programmer to code, or do some coding themselves.

Programming would probably be important to a software engineer and nearly irrelevant to a hardware engineer.

Language consists of a set of strings (syntactically correct programs) of characters from some alphabet of symbols.

Grammar

-Formal definition of the syntax of the language.

-It naturally defines the hierarchical structure of many PL's.
