$1.$ Consider the declaration: int n$[10]$: What is the index of the last element of this array?

a$.$ Compiler issues an error message

$2.$ Suppose v is an array with $100$ int elements. If $100$ is assigned to v $[100],$ what happens?

c$.$ Program will terminate immediately

$.$ Compiler issues a warning message. b

d$.$ Another variable or array will very likely be unexpectedly modified

$3.$ Show contents of the array after the code shown:

double money$[4]$ double temp; $(75,50,5,4)$; if $($money$[1]>$ money $[2])$ money $[2]$ temp;

temp money$[1]$; money$[1]$ money$[2]$;

$\}$

$4.$ Write a statement to declare an array named scores of twenty$-$five integer elements.

$5.$ Write a statement that declares an array of characters named letterGrades that contains exactly eighty elements.

$6.$ Using one statement, declare an array named taxRates of $5$ elements of type double and initialize the elements to the values $0\mathrm{.}10,0\mathrm{.}15,0\mathrm{.}21,0\mathrm{.}28,0\mathrm{.}31,$ respectively.

$7.$ An array of integers named salarySteps contains five elements and has already been declared and initialized.

Write a statement that assigns the value $160000$ to the last element of the array salarySteps.

$8.$ An array named values, containing exactly five integers has already been declared and initialized. Write a single statement to add $10$ to the value stored in the first element of the array.

$9.$ An array of integers named list contains exactly five elements and has already been declared and initialized.

Write a single statement that assigns a new value to the first element of the array that is equal to twice the value stored in the last element of the array. $($Do not modify any values in the array other than the first element.$)$

$10.$ Given a character array named arr, along with two int variables i and j$,$ write some code that swaps the values of arr$[$i$]$ and arr$[$j$].$ Declare one additional variable.
