Explanation:
Stack is LIFO data structure (Last In First Out) where the last element entered in stack will be the last one to be out of stack. It has three operations: push() : used to insert an element in stack, pop() : used to delete an element from the stack, top() : used to return the top of the stack i.e. the newest member of the stack. All these operations will take place at the top.
<u>Explanation:</u>
Now, looking at the program, x and y are initialized the values of 2 and 3 respectively. The stack pushes 8 onto the stack making it the first member of the stack. Then the value of x which is 2 is pushed onto the stack. Next, (x+5) = (2+5) = 7 is pushed onto the stack.
Pop() is used to delete hence 7 is popped out from the stack. top() is assigned to y which is 2 in this case and again 2 is popped out from the stack. Now, (x+y) = (2+2) = 4 is pushed onto the stack. And the top() is assigned to x which is 4. 4 is again popped out from the stack. Hence the value of x is 4.

The answer to this question can be given as:
In this question the option b,c, and d are correct.
Explanation:
A (DBMS) stands for a database management system. The DBMS is a software package that is used for crate, update, and delete. The database uses the SQL which stands for the structured query language. It is a programming language that uses the queries. These queries are used to providing many operations in the database like crate table, update table, join table, create a view of the table, etc. In the database, we can view the code of the join table and is also used to hide the complexity of retrieval operations, it can help in the update the table in a single statement.
T<span>he seven steps used by a laser printer to print a page are :
</span>1) Processing, this is where he computer sends the data to the printer.
2) Charging, where <span>the wire (primary corona) negatively charges the
photoconductive drum.</span>
3) Exposing, where <span>the laser scans the image to the drum. Anywhere the
laser touches the drum causes the electrical charge to drain off.</span>
4) Developing, where <span>negatively charged toner particles are allowed to
attach to the painted area of the drum; since the negative charge has
been drained off these areas</span>
5) Transferring, where the transfer corona wire charges the paper with a
positive charge from behind. The negatively charged toner jumps to the
positive paper, according to the image on the drum. <span>A Static Charge
eliminator then removes any residual charge.
</span>6) Fusing, where t<span>he toner particles attached to the paper are fused or
melted to the paper, because of the heated drum.</span>
7) Cleaning, where t<span>he drum is cleaned of excessive toner and electrical
charges.</span>
