please solve them in using c++

1) Write a line code in C++ of erasing an element from a list.

1b) print out the elements of stack in class (code only).

2) implement a list using the vector class with at least two operations in C++.

5) You are given an array, A, containing n numbers in order. Describe in pseudocode an

efficient algorithm for reversing the order of the numbers in A using a stack for-loop that

indexes the cells of A, to insert each element into a stack, and then another for loop that

removes the elements from the stack and puts them back into A in reverse order.

what is the running time for this algorithm?

6) implement the Queue data structure; performing at least two operations.
