If the analyst is able to get the source system to insert into the system a message chosen by the analyst, a SQL injection attack is possible.
SQL injection attack:-
A SQL injection attack is a type of cybersecurity attack in which the attacker injects malicious SQL code into a database query, enabling the attacker to access, modify, or delete data within the database. The attack typically occurs through input fields such as login or contact forms on web pages.
As a result, the attacker can potentially gain unauthorized access to sensitive data. The SQL injection attack may allow an attacker to extract sensitive data, delete data, modify or tamper with data, or gain full control over the system.
If the analyst can manipulate the source system to insert a message chosen by them, it suggests that there might be a vulnerability in the system's input validation or sanitization mechanisms, making it susceptible to SQL injection attacks.

in cell c12 enter a formula using a counting function to count the number of items in the item column cell c2:c11
To count the number of items in the item column (C2:C11) and display the result in cell C12, you can use a counting function called COUNTA.
The formula to achieve this is:
=COUNTA(C2:C11)
The COUNTA function counts all non-empty cells within the specified range. In this case, it will count the number of cells in the range C2:C11 that contain a value, and display the result in cell C12.
Note that if there are any blank cells within the specified range, the COUNTA function will still count them as part of the total.
To enter a formula in cell C12 using a counting function to count the number of items in the item column from cells C2 to C11, follow these steps:
1. Click on cell C12 to make it active.
2. Type the formula `=COUNTA(C2:C11)` which uses the COUNTA function to count the number of non-empty cells in the range C2:C11.

What is the rationale for the above response?The function has an empty return statement, which is a placeholder and doesn't provide the desired functionality. The code includes the necessary header files and library functions, such as "vector" and "pair", which can be used to implement the summarize function.

What factors determine which deadlock strategy to use in a given system? In other words, if you were implementing a system, how would you decide which deadlock strategy to use?
When deciding which deadlock strategy to use in a system, several factors should be considered.
First, the nature of the system and its potential for deadlocks should be assessed through thorough analysis. The resource allocation and concurrency requirements of the system play a crucial role. If the system is prone to deadlocks, prevention strategies like resource ordering or deadlock avoidance may be appropriate.
However, if the system cannot avoid deadlocks, detection and recovery strategies, such as using deadlock detection algorithms or implementing a deadlock detection mechanism, become necessary.
The choice of strategy ultimately depends on the specific characteristics and needs of the system to ensure efficient resource utilization and prevent deadlock situations.

Duplicate data is common in a variety of settings, including data management and personal finance software. Users may have entered the same data twice, resulting in two identical entries for the same person or item.
The presence of duplicates in a data set can make data analysis more difficult and result in inaccurate results. As a result, duplicate data detection and elimination are essential in ensuring data quality and accuracy.In the context of databases, a unique index is frequently used to guarantee that data is entered only once.

explain how you would redesign the dataviz class using the adapter pattern so that dataviz can be configured at runtime to use either superstats or uberstats.
The adapter pattern should be used to allow dataviz to be configured at runtime to use either superstats or uberstats. You can use this pattern to create a class that adapts the interface of dataviz to the interface of superstats or uberstats.
What is the adapter patternThe adapter pattern is a software design pattern that enables the interface of an existing class to be used by another class. This pattern is used to make two incompatible interfaces compatible with one another by converting the interface of one class into another interface that the other class requires.
How to redesign the dataviz class ?To redesign the dataviz class using the adapter pattern, follow these steps:
1: Determine the interface of dataviz
The first step in redesigning the dataviz class using the adapter pattern is to determine the interface of dataviz. This interface will be used to create an adapter that adapts dataviz's interface to the interface of either superstats or uberstats.
2: Determine the interface of superstats or uberstats
The second step in redesigning the dataviz class using the adapter pattern is to determine the interface of either superstats or uberstats. This interface will be used to create an adapter that adapts dataviz's interface to the interface of either superstats or uberstats.
3: Create an adapter class
The third step in redesigning the dataviz class using the adapter pattern is to create an adapter class. This adapter class should implement the interface of superstats or uberstats and should take an instance of dataviz as a constructor parameter.
4: Implement the adapter's interface methods
The fourth step in redesigning the dataviz class using the adapter pattern is to implement the interface methods of the adapter. These methods should call the corresponding methods of dataviz.
5: Use the adapter at runtime
The final step in redesigning the dataviz class using the adapter pattern is to use the adapter at runtime. You should create an instance of the adapter class and pass it to the code that requires either superstats or uberstats.

Word frequencies - functions
Define a function named GetWordFrequency that takes a vector of strings and a search word as parameters. Function GetWordFrequency() then returns the number of occurrences of the search word in the vector parameter (case insensitive).
Then, write a main program that reads a list of words into a vector, calls function GetWordFrequency() repeatedly, and outputs the words in the vector with their frequencies. The input begins with an integer indicating the number of words that follow.
Ex: If the input is:
5 hey Hi Mark hi mark
the output is:
hey 1
Hi 2
Mark 2
hi 2
mark 2
Hint: Use tolower() to set the first letter of each word to lowercase before comparing.

Q2. You are expected to draw a circle with \( (0,0) \) centered with radius 6 units. Using midpoint circle drawing algorithm find out all the pixels of circle drawing and draw complete circle after fi
The midpoint circle drawing algorithm can be used to find and draw all the pixels of a circle centered at (0,0) with a radius of 6 units.
The midpoint circle drawing algorithm is a commonly used algorithm to draw circles in computer graphics. It works by starting at the topmost point of the circle and iteratively determining the next set of pixels to be drawn based on the midpoint between the current pixel and the next pixel.
To draw a circle centered at (0,0) with a radius of 6 units, we can use the following steps:
1. Initialize the variables: Let the initial point be (0,6) and the decision parameter be set to 5/4 - 6.
2. Set up a loop: Starting from the topmost point (0,6), we loop until the x-coordinate becomes greater than or equal to the y-coordinate.
3. Draw pixels: Inside the loop, we draw eight symmetric points by reflecting the current point about all the axes (x, y, -x, -y). These points are (x, y), (y, x), (-x, y), (-y, x), (-x, -y), (-y, -x), (x, -y), and (y, -x).
4. Update the decision parameter: At each iteration, we update the decision parameter based on whether the next pixel is inside or outside the circle. If it is inside, we increment the y-coordinate and update the decision parameter accordingly. Otherwise, we increment both the x-coordinate and the y-coordinate.
5. Repeat the loop: We repeat the loop until the x-coordinate becomes greater than the y-coordinate.
By following these steps, we can find and draw all the pixels of the circle. The resulting set of pixels will form a complete circle centered at (0,0) with a radius of 6 units.
