Answer:

C and G

Explanation:

In C language, the asterisks, ' * ', and the ampersand, ' & ', are used to create pointers and references to pointers respectively. The asterisks are used with unique identifiers to declare a pointer to a variable location in memory, while the ampersand is always placed before a variable name as an r_value to the pointer declared.

A(n) __________ can include a computer's full operating system, applications, and system settings, including security and config
babymother [125]

Solution:

It is done by Operating system.

An Operating system is system software that manages computer hardware and software resources and provides common services for computer programs.

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.

Write the definition of a void function that takes as input an integer and outputs two times the number if it is even; otherwise
KatRina [158]

Answer:

Written in C++

void number(int n){

if(n%2 == 0)

cout<<2 * n;

else

cout<<5 * n;

}

Explanation:

The programming language is not stated.

However, I answered using C++

This line defines the function as void

void number(int n){

This line checks if the number is even

if(n%2 == 0)

If yes, it doubles the number and prints the output

cout<<2 * n;

If otherwise,

else

It multiplies the number by 5 and prints the output

cout<<5 * n;

}

To call the function from main, use:

number(n);

Note than n must be declared as integer
