if bptr is assigned b (the name of an array), then array element b[3] can alternatively be referenced with the pointer expression
a) bPtr + 5 b) *b [bPtr + 5] c) b[bPtr + 5] d) *( bPtr + 5)
The correct option is c) b[bPtr + 5)
Given that bptr is assigned b (the name of an array), then array element b[3] can alternatively be referenced with the pointer expression b[bPtr + 5].Step-by-step explanation:Given that,bptr is assigned b (the name of an array).bPtr holds the base address of the array b.The expression `b[bPtr + 5]` is equivalent to *(b+8), because the value of bPtr is the address of b[0].Thus, b[bPtr + 5] is the same as b[3].
The definition of an array in C is a way to group together several items of the same type. These things or things can have data types like int, float, char, double, or user-defined data types like structures. All of the components must, however, be of the same data type in order for them to be stored together in a single array.

In which SQL injection attack does the attacker send incorrect query to the database to intentionally generate an error message
The SQL injection attack in which the attacker sends an incorrect query to the database to intentionally generate an error message is called Error-based SQL injection.
SQL injection is a cyber attack that targets the database layer of the application. It is one of the most common web application security vulnerabilities. In an SQL injection attack, the attacker sends malicious SQL statements to the database server with the aim of stealing sensitive information or modifying the data stored in the database. In an Error-based SQL injection, the attacker intentionally sends an incorrect query to the database to generate an error message that can be used to extract information from the database.
SQL injection attacks can be prevented by using prepared statements, input validation, and sanitization techniques. Application developers must be aware of the risks of SQL injection and take necessary steps to ensure the security of their applications.

Within this block, we set the color property to steelblue, which will make the unvisited hyperlinks appear in that color. Additionally, we set text-decoration to none to remove any underlines.
For visited links, we use a:visited as the selector. Similar to the unvisited links, we set the color property to orange to make the visited links appear in that color.
