Computer Programming

Its close to real world entity..

C++ is general-purpose and portable, which is common to many high-level languages, but it excels in terms of performance, comparable to that of assembly language. This is not surprising given the amount of work that goes into optimising the native machine code that the C++ compiler produces.

Java is arguably more popular today (especially with amateur programmers), but it doesn't perform well when compared to C++. This is largely due to the much higher level of abstraction which requires compiled programs to be executed and interpreted by the Java virtual machine. The main advantage of Java is that the abstraction allows Java programs to be run on any platform that supports the JVM without the need to modify the source code and recompile, which is the main disadvantage of C++. However, in terms of performance alone, few languages can compete with C++, hence its huge popularity in the community.

The purpose of extreme programming methodology is to improve software quality and responsiveness to meet the customer's requirements. As frequent changes require updated programming to make things run smoothly.

What type of a program is used in order to enter C source code

to write and read the values

Delphi was the Oracle of Apollo. It was there that mortals went to seek answers to their future. A young priestess sat on a tripod, inhaling fumes from the crevice that she sat by, and priests told the seeker what she had said. It was usually ambiguous, and the seeker had to figure out the meaning of it.

Besides the second letter of the alphabet it can also mean bytes.

A compiler is a program that translates a programming language (like c++, java, pascal, php etc...) to a language that computers can "understand" (i.e. "1001010110101010...")

No one on this site will know how do this. It's far too complicated, as for me I think you need to figure out how to do this yourself.

Before shutting down your system Close all open file and folders. Follow these step:-

1. Click start Button or Windows Logo Left bottom corner

2. Click Shut Down.

Or you can use also shut down using CTRL ALT Delete button. or need any assistant call Techvedic expert.

A constructor in a class is one of the first pieces of code to be executed when you instantiate a class. The purpose of constructors is to have code that initialize the class and prepare the variables that may be required by the class...

JavaScript is one program that has been written in C to implement the Apriori algorithm. There are also several other known programs available on the Internet that implement it as well.

I dedicate this research work to my subject teacher who never failed to teach and guide me, to my family who supports me in everything, to my friends who helped me finished this project, and most of all to the Almighty God who gives me strength and good health while doing this.

for C: sizeof (int), often 2 or 4 byte
for Java: 4 byte

i want a c programme....if i have a collection of alphabhate appox 2000 or

more...alphabates r repeted...

i want to write a prograam such that first 7 terms r wrriten in first

No. Computer essentials relate to the basic hardware knowledge (identifying input/output devices, the processor and storage devices), operations and general usage (executing and using programs such as a word processor and a spreadsheet) and file maintenance (organising, saving and deleting user documents). Computer programming requires skill and knowledge that exceeds the basic requirements of computer essentials.

the answer is 304C

Speed and accuracy.
