Assume that x is a variable that has been declared as an int and been given a value. Assume that twice is a method (in the same class as the caller) that receives a single integer parameter and returns twice its value. (So if you pass 7 to twice it will return 14. Thus the expression twice(7) has the value 14. Write an expression whose value is eight times that of x without using the standard Java arithmetic operators (*,+, etc.). Instead, use calls to twice to accomplish this. In this exercise you must write this as a single expression-- you must not write any statements. Also, you may only use the twice() function-- no other functions or operators.

Arrays are indexed from 0 in pretty much every language, except stupid Microsoft languages.

Lets say that ARR_SIZE is 5 for example.

So you have an array of 5 elements. They are indexed from 0 - 4.

arr[0] // First element

arr[4] // Last element

Therefore arr[ ARR_SIZE -1 ] is the last element of the array.

That's why for loops to iterate through arrays are wrote like:

for(int i = 0; i < ARR_SIZE; ++i)

answer; insolated i/o uses separate memory space,and on the other hand memory mapped i/o uses memory from the main

answer is:

a). backstage view

explanation:

backstage view is the area where files and data about them is managed— creating, saving, printing, sending to others, inspecting for hidden metadata or personal information, and setting options. so in this way we can add many things to our document swiftly.

i hope you get the idea.
