suppose we'd like to add an item to the end (push back) of two data structures: a linked list and a vector. which data structure is technically faster in the worst case?

Answers

Suppose we'd like to add an item to the end (push back) of two data structures: a linked list and a vector. In the worst-case scenario, which data structure is technically faster?

We should note that a vector is more effective than a linked list for most types of data in this case. In terms of big O notation, adding to a vector has a time complexity of O(1) at best, whereas adding to a linked list has a time complexity of O(n) at worst, which is significantly slower than adding to a vector.

Furthermore, memory access is a crucial component of a program's overall efficiency. A vector's contents are kept together in memory, and the CPU's cache can load the data faster. When data is kept in separate memory blocks, such as in a linked list, the CPU will be forced to fetch each memory block separately, lowering the program's efficiency. Therefore, in the worst-case scenario, a vector is technically faster than a linked list.

Answers

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.

How to assign the address of a variable to a pointer?

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.
