Data abstraction and data independence are two key concepts in computer science and database management systems. They are closely related and aim to improve the efficiency, flexibility, and maintainability of data management.

The definitions of these two are:

Data Abstraction:

Data abstraction refers to the process of hiding the implementation details of data and providing a simplified view or interface to interact with it. It allows users to focus on the essential aspects of data without being concerned about the underlying complexities. In programming languages, data abstraction is often achieved through the use of abstract data types (ADTs) or classes.

By abstracting data, programmers can create high-level representations of data entities, defining their properties and operations.

Data Independence:

Data independence refers to the ability to modify the data storage structures and organization without affecting the higher-level applications or programs that use the data. It allows for changes to be made to the database system without requiring corresponding modifications to the applications that rely on that data. Data independence provides flexibility, scalability, and ease of maintenance in database systems.

(4.1) 14 base 10 = 1102 base 3

To convert a number from base 10 to base 3, we repeatedly divide the number by 3 and write down the remainders. The remainders are read from right to left to form the number in base 3.

14 / 3 = 4 with remainder 2

4 / 3 = 1 with remainder 1

Therefore, 14 in base 10 is equal to 1102 in base 3.

(4.2) B2 base 16 = 10110010 base 2

To convert a number from base 16 to base 2, we repeatedly divide the number by 2 and write down the remainders. The remainders are read from right to left to form the number in base 2.

B2 / 2 = 51 with remainder 0

51 / 2 = 25 with remainder 1

25 / 2 = 12 with remainder 1

12 / 2 = 6 with remainder 0

6 / 2 = 3 with remainder 0

3 / 2 = 1 with remainder 1

Therefore, B2 in base 16 is equal to 10110010 in base 2.

Explanation:

Certainly! Here are the steps to convert the given numbers from one base to another:

1. Converting (4.1) from base 10 to base 3:

\((4.1)_{10}\) = ?? base 3

To convert a number from base 10 to base 3, we need to divide the number successively by 3 and record the remainders until the quotient becomes zero. Then, we read the remainders in reverse order to get the equivalent number in base 3.

Here are the steps:

Step 1: Divide 14 by 3

\(\left\lfloor \frac{14}{3} \right\rfloor = 4\) (quotient)

\(14 \mod 3 = 2\) (remainder)

Step 2: Divide 4 by 3

\(\left\lfloor \frac{4}{3} \right\rfloor = 1\) (quotient)

\(4 \mod 3 = 1\) (remainder)

Step 3: Divide 1 by 3

\(\left\lfloor \frac{1}{3} \right\rfloor = 0\) (quotient)

\(1 \mod 3 = 1\) (remainder)

Since the quotient is now 0, we stop. The remainders in reverse order are 112. Therefore, (4.1) base 10 is equivalent to \((112)_3\).

2. Converting (4.2) from base 16 to base 2:

\((4.2)_{16}\) = ?? base 2

To convert a number from base 16 to base 2, we need to convert each digit of the number from base 16 to base 2.

Here are the steps:

Step 1: Convert the digit B to base 2

B in base 16 is equal to 1011 in base 2.

Step 2: Convert the digit 2 to base 2

2 in base 16 is equal to 0010 in base 2.

Combining the converted digits, we get \((4.2)_{16} = (1011.0010)_2\) in base 2.

Answer:

C programming has three types of loops.

for loop

while loop

do...while loop

In the previous tutorial, we learned about for loop. In this tutorial, we will learn about while and do..while loop.

while loop

The syntax of the while loop is:

while (testExpression) {

 // the body of the loop

}

How while loop works?

The while loop evaluates the testExpression inside the parentheses ().

If testExpression is true, statements inside the body of while loop are executed. Then, testExpression is evaluated again.

The process goes on until testExpression is evaluated to false.

If testExpression is false, the loop terminates (ends).

To learn more about test expressions (when testExpression is evaluated to true and false), check out relational and logical operators.

Flowchart of while loop

flowchart of while loop in C programming

Working of while loop

Example 1: while loop

// Print numbers from 1 to 5

#include <stdio.h>

int main() {

 int i = 1;

 while (i <= 5) {

   printf("%d\n", i);

   ++i;

 }

 return 0;

}

Run Code

Output

1

2

3

4

5

Here, we have initialized i to 1.

When i = 1, the test expression i <= 5 is true. Hence, the body of the while loop is executed. This prints 1 on the screen and the value of i is increased to 2.

Now, i = 2, the test expression i <= 5 is again true. The body of the while loop is executed again. This prints 2 on the screen and the value of i is increased to 3.

This process goes on until i becomes 6. Then, the test expression i <= 5 will be false and the loop terminates.

do...while loop

The do..while loop is similar to the while loop with one important difference. The body of do...while loop is executed at least once. Only then, the test expression is evaluated.

The syntax of the do...while loop is:

do {

 // the body of the loop

}

while (testExpression);

How do...while loop works?

The body of do...while loop is executed once. Only then, the testExpression is evaluated.

If testExpression is true, the body of the loop is executed again and testExpression is evaluated once more.

This process goes on until testExpression becomes false.

If testExpression is false, the loop ends.

Flowchart of do...while Loop

do while loop flowchart in C programming

Working of do...while loop

Example 2: do...while loop

// Program to add numbers until the user enters zero

#include <stdio.h>

int main() {

 double number, sum = 0;

 // the body of the loop is executed at least once

 do {

   printf("Enter a number: ");

   scanf("%lf", &number);

   sum += number;

 }

 while(number != 0.0);

 printf("Sum = %.2lf",sum);

 return 0;

}

Run Code

Output

Enter a number: 1.5

Enter a number: 2.4

Enter a number: -3.4

Enter a number: 4.2

Enter a number: 0

Sum = 4.70

Here, we have used a do...while loop to prompt the user to enter a number. The loop works as long as the input number is not 0.

The do...while loop executes at least once i.e. the first iteration runs without checking the condition. The condition is checked only after the first iteration has been executed.

do {

 printf("Enter a number: ");

 scanf("%lf", &number);

 sum += number;

}

while(number != 0.0);

So, if the first input is a non-zero number, that number is added to the sum variable and the loop continues to the next iteration. This process is repeated until the user enters 0.

But if the first input is 0, there will be no second iteration of the loop and sum becomes 0.0.

Outside the loop, we print the value of sum.

d. Individually testing a small part (or unit) of a program, typically a function, using a separate program called a test harness.

Explanation:

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are;

1. Planning.

2. Analysis.

3. Design.

4. Development (coding).

5. Testing.

6. Implementation and execution.

7. Maintenance.

Unit testing can be defined as a software development procedure that involves the process of individually testing a small part (or unit) of a program, typically a function, using a separate program called a test harness.

This ultimately implies that, if the observed behavior of the small part of a software program is consistent with the expectations, then the unit test is considered a pass. Otherwise, the unit test failed.

In this case, the domain of values for the SSN column is 9-digit numbers that represent a government-issued identifier and are unique to each employee.

What are the domains of values?

The "domain of values" of a column (attribute) in a relational database refers to the set of possible values that the column can hold. In the case of the SSN column, the domain of values is 9-digit numbers that represent a government-issued identifier and are unique to each employee.
