Exercises 7.6(Fill in the Blanks) Fill in the blanks in each of the following:
a) The names of the four elements of array p are ____, ____, ____ and ____.
b) Naming an array, stating its type and specifying the number of elements in the array is called ____ the array.
c) When accessing an array element, by convention, the first subscript in a two-dimensional array identifies an element's ____ and the second subscript identifies an element's ____.
d) An m-by-n array contains ____ rows, ____ columns and ____ elements.
e) The name of the element in row 3 and column 5 of array d is ____.

Fill in the blanks for the given statements related to arrays.
Explanation of Solution
- Given statement: The names of the four elements of array p are p[0], p [1], p[2] and p[3].
- Naming an array, stating its type and specifying the number of elements in the array is called declaring the array.
- When accessing an array element, by convention, the first subscript in a two-dimensional array identifies an element’s row number , and the second subscript identifies an elements’ column number.
- An m-by-n array contains m rows, n columns and m*n elements.
- The name of the element in row 3 and column 5 of array d is d[3][5].
To refer to any single element of the array are, you need to specify the name of the array and its position. Positions of elements of a n-size array are indexed from n = 0 till n − 1. So four elements of array p will be p[0], p[1], p[2], and p[3].
Declaration of array involved specifying the name of the array, along with its size and type. For example,
double p[10]; //declaration
This means an array of size 10, name p & type double has been declared.
An array comprises of rows & columns. The first subscript is row & second is column number. For example,
double p[9][10]- means element in the 9th row & 10th Column
The size of an array is given as the product of its row & columns. Example, for array a[10][2]- the total number of elements will be 10*2=20 and it will have 10 rows and 12 columns.
Name of element includes row & column number- with row number followed by column number.

This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle. Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…arrow_forwardSolve this "Do not use AI tools.
