C++ and C+ programing

Question 1

C++

Answer 1

It is a compiled language, with implementations of it available on many platforms. Various organizations provide them, including the FSF, LLVM, Microsoft and Intel.

Question 2

C++

Answer 2

It is designed with a bias for systems programming (e.g. embedded systems, operating system kernels), with performance, efficiency and flexibility of use as its design requirements. C++ has also been found useful in many other contexts, including desktop applications, servers (e.g. e-commerce, web search, SQL), performance critical applications (e.g. telephone switches, space probes) and entertainment software, such as video games

Question 3

Hello world

Answer 3

include

int main()
{
   std::cout << "Hello, world!\n";
}

Question 4

Platform

Answer 4

The Android platform is Google Inc.’s open and free software stack that includes an operating system, middleware and also key applications for use on mobile devices, including smartphones. Android is an Open Handset Alliance Project.

Question 5

SDK Package

Answer 5

A software development kit that enables developers to create applications for the Android platform. The Android SDK includes sample projects with source code, development tools, an emulator, and required libraries to build Android applications. Applications are written using the Java programming language and run on Dalvik, a custom virtual machine designed for embedded use which runs on top of a Linuxkernel.

Question 6

Linux Kernel

Answer 6

The Linux kernel is a Unix-like operating system kernel used by a variety of operating systems based on it, which are usually in the form of Linux distributions.[8] The Linux kernel is a prominent example of free and open source software

Question 7

Linux Kernel

Answer 7

Linux kernel is the most popular operating system kernel; in addition to a wide variety of devices that use the Linux kernel, huge numbers of Android-based devices contribute largely to the overall kernel’s popularity

Question 8

Source Code

Answer 8

In computing, source code is any collection of computer instructions (possibly with comments) written using some human-readable computer language, usually as text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code.

Question 9

Encryptions

Answer 9

For example, the Computer Security Institute reported that in 2007, 71% of companies surveyed utilized encryption for some of their data in transit, and 53% utilized encryption for some of their data in storage.[7] Encryption can be used to protect data “at rest”, such as files on computers and storage devices (e.g. USB flash drives). In recent years there have been numerous reports of confidential data such as customers’ personal records being exposed through loss or theft of laptops or backup drives. Encrypting such files at rest helps protect them should physical security measures fail. Digital rights management systems, which prevent unauthorized use or reproduction of copyrighted material and protect software against reverse engineering (see also copy protection), is another somewhat different example of using encryption on data at rest
