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?
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.

It is a good idea to make a copy constructor's parameters constant by specifying the const keyword in the parameter list. viz. c.) constant, const.
What exactly is a constructor?A constructor is a particular method used to build an object in object-oriented programming. The constructor is in charge of establishing the object's initial state, including any member variables or other data. The constructor is automatically called when an object is created, making it an important aspect of the object's lifetime.
A copy constructor produces a new object with identical characteristics to an existing object. The copy constructor is used to generate a new object that is the same as the original but has different memory addresses. The parameters of the copy constructor must be constant since they are not anticipated to change when the constructor is invoked.
