What is many to many junction?
When numerous records in one table are linked to several records in another table, this is known as a many-to-many relationship.
The simplest method is to utilize a Junction Table when you need to create a many-to-many link between two or more tables. By referring to the main keys of each data table, a junction table in a database, also known as a bridge table or associative table, connects the databases.
A many-to-many relationship, or type of cardinality, is used in systems analysis to describe the relationship between two entities, such as A and B, where A may have a parent instance for whom there are many offspring in B and vice versa.

The destination operand of the or instruction cannot be a memory operand.
a. True
b. False
The given statement is false. By performing a bitwise OR operation, the OR instruction supports logical expression.
What is OR instruction?By performing a bitwise OR operation, the OR instruction supports logical expression. If the matched bits from either or both operands are 1, the bitwise OR operator returns 1. If both of the bits are zero, it returns 0. One or more bits may be set using the OR operator. A bitwise instruction is an OR instruction. This implies that the digits of two integers with the same amount of bits (for example, two 32-bit numbers) are handled bit by bit (and not the complete number). If both "input" bits are 0, the OR instruction produces a result of 0, and a result of 1, if at least one input bit is a 1.A memory operand cannot be the destination operand of the OR instruction. The destination operand is always changed by the TEST instruction. The Zero flag is always set when an operand is XORed with 1. The two's complement of an integer can be created by applying the XOR instruction to it.The given statement is false. By performing a bitwise OR operation, the OR instruction supports logical expression.To learn more about OR instruction refer to:

Errors can be syntax errors or logic errors (the code works, but not as intended). In the Guess My Number game, there is a lower limit and an upper limit for the range of possible numbers to guess. If the lower limit were exclusive and the upper limit inclusive, which expression would properly generate values for the secret number?
(int)(Math.random() * (upper − lower + 1) ) + lower
(int)(Math.random() * (upper − lower) ) + lower + 1
(int)(Math.random() * (upper − lower + 1) ) + lower - 1
Errors can be syntax errors or logic errors (the code works, but not as intended) is option A: (int)(Math.random() * (upper − lower) ) + lower
What is the syntax errors about?The phrase that would correctly provide results for the secret number if the lower limit were inclusive and the upper limit exclusive is Option A
Note that we cannot increase the lower limit by one because it is INCLUSIVE. Additionally, the Math.random() function returns a result between [0,1[ that satisfies our requirements (meaning the 0 is included, but not the 1).
Therefore, We'll be flawless if the (int) caster returns only the integer component after rounding down the result.
