What feature allows a person to key on the new lines without tapping the return or enter key

Answers

The feature that allows a person to key on new lines without tapping the return or enter key is called word wrap

How to determine the feature

When the current line is full with text, word wrap automatically shifts the pointer to a new line, removing the need to manually press the return or enter key.

In apps like word processors, text editors, and messaging services, it makes sure that text flows naturally within the available space.

This function allows for continued typing without the interruption of line breaks, which is very helpful when writing large paragraphs or dealing with a little amount of screen space.

In JAVA with comments: Consider an array of integers. Write the pseudocode for either the selection sort, insertion sort, or bubble sort algorithm. Include loop invariants in your pseudocode.

Answers

Here's a Java pseudocode implementation of the selection sort algorithm with comments and loop invariants:

```java

// Selection Sort Algorithm

public void selectionSort(int[] arr) {

   int n = arr.length;

   for (int i = 0; i < n - 1; i++) {

       int minIndex = i;

       // Loop invariant: arr[minIndex] is the minimum element in arr[i..n-1]

       for (int j = i + 1; j < n; j++) {

           if (arr[j] < arr[minIndex]) {

               minIndex = j;

           }

       }

       // Swap the minimum element with the first element

       int temp = arr[minIndex];

       arr[minIndex] = arr[i];

       arr[i] = temp;

   }

}

```The selection sort algorithm repeatedly selects the minimum element from the unsorted part of the array and swaps it with the first element of the unsorted part.

The outer loop (line 6) iterates from the first element to the second-to-last element, while the inner loop (line 9) searches for the minimum element.

The loop invariant in line 10 states that `arr[minIndex]` is always the minimum element in the unsorted part of the array. After each iteration of the outer loop, the invariant is maintained.

The swap operation in lines 14-16 exchanges the minimum element with the first element of the unsorted part, effectively expanding the sorted portion of the array.

This process continues until the entire array is sorted.

Remember, this pseudocode can be directly translated into Java code, replacing the comments with the appropriate syntax.

Question 3 3.1 Describe the TWO main elements of a CPU 3.2 Describe the fetch/execute cycle 3.3 Convert the binary number 00000011 to a decimal ​

Answers

Answer:

Here are the answers to the questions:

3.1 The two main elements of a CPU are:

The Control Unit (CU): The CU controls and coordinates the operations of the CPU. It is responsible for interpreting instructions and sequencing them for execution.

The Arithmetic Logic Unit (ALU): The ALU executes arithmetic and logical operations like addition, subtraction, AND, OR, etc. It contains registers that hold operands and results.

3.2 The fetch/execute cycle refers to the cycle of events where the CPU fetches instructions from memory, decodes them, and then executes them. The steps in the cycle are:

Fetch: The next instruction is fetched from memory.

Decode: The instruction is decoded to determine what it is asking the CPU to do.

Execute: The CPU executes the instruction. This could involve accessing data, performing calculations, storing results, etc.

Go back to Fetch: The cycle continues as the next instruction is fetched.

3.3 The binary number 00000011 is equal to the decimal number 3.

Binary: 00000011

Decimal: 1 + 2 = 3

So the conversion of the binary number 00000011 to decimal is 3.

The Biography and Life of Henry Ford.

Column One: Who was Henry Ford?

Henry Ford was the founder of Ford Motor Company and also the mass producer of the automobile. Henry Ford was born in 1863. At the age of 16, he worked as a machinist apprentice. Later, Henry began to work the family farm while still working on creating steam engines. Henry had a big interest in steam engines, which would later contribute to him building his first working automobile.

Column Two: How did Henry Ford contribute to our society?

After marrying in 1888, Ford was hired to work for Edison Illuminating Company. His position was an engineer, and Ford began to accelerate his position in the company quickly. After a while, Ford created his first operating vehicle. This was called the "Quadricycle." Ford wanted to improve on his models, so he founded the Company Ford with others. Ford then began to develop methods of mass-producing automobiles to sell to the public. After success in business, he bought the whole company and owned it all by himself. Ford began to mass-produce automobiles. It is said that " The mass production techniques Henry Ford championed eventually allowed Ford Motor Company to turn out one Model T every 24 seconds." Ford passed away in 1945. He decided to give ownership to his son Edsel Ford before he died, but Edsel sadly died before Henry Ford. The Ford company's ownership was given to Ford's grandson, Henry Ford II.

From the window select the tables that need to be used in the query, here Student and PaymentPlan tables are selected.Select the desired fields from each table, here we need StudentID, PaymentPlan, and BalanceDue from the Student table and StudentID, PaymentPlan from PaymentPlan table.Drag and drop the desired fields to the Query Design grid.

Now comes the main part of the query that is grouping. Here we need to group the total outstanding balances of students who are on a payment plan and who are not on a payment plan. We will group the data by PaymentPlan field.

The query design grid should look like this:

Now, to show the query results only the sum of the balance due, grouped by PaymentPlan, a new column Balances needs to be created. In the field row, enter Balances:

Sum([BalanceDue]). It will calculate the sum of all balance dues and rename it as Balances. Save the query by the name TotalBalancesByPlan.Close the query design window. The final query window should look like this:

The above image shows that the balance due for Payment Plan A is $19,214.10, while for Payment Plan B it is $9,150.50.

Now, in order to resize all columns in the datasheet to their best fit, select the Home tab and go to the Formatting group. From here select the AutoFit Column Width option.

The final output should look like this:

Thus, a query has been created that lists the total outstanding balances for students on a payment plan and for those students that are not on a payment plan.
