vesna_86 [32]

Answer:

Option A is correct.

Explanation:

A janitor that collects data through reviewing reports on a business counsel's desk could be a tippee for insider trading activities.

Probably, the justification for insider trading remains wrong being that it offers each insider the undue benefit on and around the marketplace, gets the insider's preferences beyond them for which they assume the trustee responsibility, as well as enables the insider to unfairly manipulate the cost of the inventory of a business.

So, the following are the reason the other options are not correct according to the given scenario.

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
