if the stack has room enough for 4 elements, can the program possibly handle an expression of 10 characters?
In this scenario, the stack has a maximum capacity of 4 elements, which means that it can only hold 4 values at any given time.
However, an expression with 10 characters would require more than 4 elements to be evaluated, which means that the stack would not be able to handle the expression.
In programming, a stack is a data structure that allows for the storage and retrieval of data in a specific order. A stack typically has a fixed size or maximum capacity, and it can only hold a certain number of elements at a time.

what solution puts the stolen vehicles database in 3nf by breaking up this one big table into several tables?
To convert the stolen vehicles database into 3NF (Third Normal Form), the big table should be broken down into several smaller tables that contain the necessary information.
The process involves the following steps:
1. Identify the columns that contain the same data in multiple records, and create a new table for each of these columns.
2. Make sure that each table contains a primary key that uniquely identifies a record, as well as other attributes which together form a composite key.
3. Define relationships between tables, either one-to-one or one-to-many.
4. Make sure that each table contains only the information that is necessary for it, and that all other data is moved to other tables.
5. Check for anomalies such as insertion, update, and deletion, and take care of them by creating more tables or modifying the existing ones.
By following these steps, the big table can be broken down into several smaller tables and the stolen vehicles database can be converted into 3NF.

a.int* myPtr = *myInt;
b.int* myPtr = myInt;
c.int* myPtr = &myInt;
d.int& myPtr = &myInt
Option C: int* myPtr = &myInt; is the following statement used to assign the address of the variable int myInt to the pointer int* myPtr.
What are pointers and addresses?In C++, pointers are variables that store the memory address of another variable. A pointer is essentially an address. It points to a memory address, indicating where a variable is stored in memory. A pointer should be declared as the data type of the variable it points to, followed by an asterisk.
For example, if a pointer points to an int, it should be declared as int*. A memory address is a unique identifier for a specific memory location. It is a reference point for a particular byte of memory. Each byte in memory has a distinct memory address.
To assign the address of a variable to a pointer, use the address-of operator & followed by the variable name. For example, to assign the address of the variable int myInt to the pointer int* myPtr, use the following statement: int* myPtr = &myInt.
Therefore, option C, int* myPtr = &myInt, is the correct answer.
