<h2>The alignment of the text will be "left" by default</h2>

Explanation:

In Excel or spreadsheet, if any number is entered, it will automatically be aligned to right because right alignment is preferable for the numbers.
In case of any alignment is mentioned in the cell in prior to entering text or if the type of data is changed after or before entering the text, then the text is aligned accordingly.
According to the given scenario, a number "25" is entered and it is converted to text. So a text format will preserve the alignment as entered. By default it will be "left" aligned.

Translate the following MIPS code to C. Assume that the variables f, g, h, i, and j are assigned to registers $s0, $s1, $s2, $s3

Romashka [77]

Answer:

f = 2 * (&A[0])

See explaination for the details.

Explanation:

The registers $s0, $s1, $s2, $s3, and $s4 have values of the variables f, g, h, i, and j respectively. The register $s6 stores the base address of the array A and the register $s7 stores the base address of the array B. The given MIPS code can be converted into the C code as follows:

The first instruction addi $t0, $s6, 4 adding 4 to the base address of the array A and stores it into the register $t0.

Explanation:

If 4 is added to the base address of the array A, then it becomes the address of the second element of the array A i.e., &A[1] and address of A[1] is stored into the register $t0.

C statement:

$t0 = $s6 + 4

$t0 = &A[1]

The second instruction add $t1, $s6, $0 adding the value of the register $0 i.e., 32 0’s to the base address of the array A and stores the result into the register $t1.

Explanation:

Adding 32 0’s into the base address of the array A does not change the base address. The base address of the array i.e., &A[0] is stored into the register $t1.

C statement:

$t1 = $s6 + $0

$t1 = $s6

$t1 = &A[0]

The third instruction sw $t1, 0($t0) stores the value of the register $t1 into the memory address (0 + $t0).

Explanation:

The register $t0 has the address of the second element of the array A (A[1]) and adding 0 to this address will make it to point to the second element of the array i.e., A[1].

C statement:

($t0 + 0) = A[1]

A[1] = $t1

A[1] = &A[0]

The fourth instruction lw $t0, 0($t0) load the value at the address ($t0 + 0) into the register $t0.

Explanation:

The memory address ($t0 + 0) has the value stored at the address of the second element of the array i.e., A[1] and it is loaded into the register $t0.

C statement:

$t0 = ($t0 + 0)

$t0 = A[1]

$t0 = &A[0]

The fifth instruction add $s0, $t1, $t0 adds the value of the registers $t1 and $t0 and stores the result into the register $s0.

Explanation:

The register $s0 has the value of the variable f. The addition of the values stored in the regsters $t0 and $t1 will be assigned to the variable f.

C statement:

$s0 = $t1 + $t0

$s0 = &A[0] + &A[0]

f = 2 * (&A[0])

The final C code corresponding to the MIPS code will be f = 2 * (&A[0]) or f = 2 * A where A is the base address of the array.

Write a program that asks the user for the name of a text file. the program should display the last 10 lines of the file on the

Tom [10]

The only thing that I know is that after you input the text file, it could either:
-save those lines as a variable
-display the text file
However any more would be dependent on the language.

Technician A says that oil for the rod bearings comes from splash off the crankshaft. Technician B says that lubrication to the

worty [1.4K]

Answer: technician B

Explanation:

The oil is picked up from the oil pump though a pick up tube that is mounted on the oil pump. The end of the pick up tube sits in the oil at the bottom of the oil pan. The oil is then forced through holes that are drilled into the block. Those holes which are called (journals) lead to the main bearings,rod bearings,lifters, camshaft, ect..

Write a GUI-based program that allows the user to open, edit, and save text files. The GUI should include a labeled entry field

Korvikt [17]

to create a simple notepad in Python using Tkinter. This notepad GUI will consist of various menu like file and edit, using which all functionalities like saving the file, opening a file, editing, cut and paste can be done.

Now for creating this notepad, Python 3 and Tkinter should already be installed in your system. You can download suitable python package as per system requirement. After you have successfully installed python you need to install Tkinter (a Python’s GUI package).

Use this command to install Tkinter :

pip install python-tk

Importing Tkinter :

filter_none

edit

play_arrow

brightness_4

import tkinter

import os

from tkinter import *

# To get the space above for message

from tkinter.messagebox import *

# To get the dialog box to open when required

from tkinter.filedialog import *

Note : messagebox is used to write the message in the white box called notepad and filedialog is used for the dialog box to appear when you are opening file from anywhere in your system or saving your file in a particular position or place.

Adding Menu :

filter_none

edit

play_arrow

brightness_4

# Add controls(widget)

self.__thisTextArea.grid(sticky = N + E + S + W)

# To open new file

self.__thisFileMenu.add_command(label = "New",

command = self.__newFile)

# To open a already existing file

self.__thisFileMenu.add_command(label = "Open",

command = self.__openFile)

# To save current file

self.__thisFileMenu.add_command(label = "Save",

command = self.__saveFile)

# To create a line in the dialog

self.__thisFileMenu.add_separator()

# To terminate

self.__thisFileMenu.add_command(label = "Exit",

command = self.__quitApplication)

self.__thisMenuBar.add_cascade(label = "File",

menu = self.__thisFileMenu)

# To give a feature of cut

self.__thisEditMenu.add_command(label = "Cut",

command = self.__cut)

# To give a feature of copy

self.__thisEditMenu.add_command(label = "Copy",

command = self.__copy)

# To give a feature of paste

self.__thisEditMenu.add_command(label = "Paste",

command = self.__paste)

# To give a feature of editing

self.__thisMenuBar.add_cascade(label = "Edit",

menu = self.__thisEditMenu)

# To create a feature of description of the notepad

self.__thisHelpMenu.add_command(label = "About Notepad",

command = self.__showAbout)

self.__thisMenuBar.add_cascade(label = "Help",

menu = self.__thisHelpMenu)

self.__root.config(menu = self.__thisMenuBar)

self.__thisScrollBar.pack(side = RIGHT, fill = Y)

# Scrollbar will adjust automatically

# according to the content

self.__thisScrollBar.config(command = self.__thisTextArea.yview)

self.__thisTextArea.config(yscrollcommand = self.__thisScrollBar.set)

With this code we will add the menu in the windows of our notepad and will add the things like copy, paste, save etc, to it.
