Project Overview: This project is for testing the use and understanding of stacks. In this assignment, you will be writing a program that reads in a stream of text and tests for mismatched delimiters. First, you will create a stack class that stores, in each node, a character (char), a line number (int) and a character count (int). This can either be based on a dynamic stack or a static stack from the book, modified according to these requirements. I suggest using a stack of structs that have the char, line number and character count as members, but you can do this separately if you wish.Second, your program should start reading in lines of text from the user. This reading in of lines of text (using getline) should only end when it receives the line “DONE”.While the text is being read, you will use this stack to test for matching “blocks”. That is, the text coming in will have the delimiters to bracket information into blocks, the braces {}, parentheses (), and brackets [ ]. A string…
Please elaborate on the distinction between the bound and unbounded stack.

Suppose that you want to create the following program: void copyStack(std::stack<int> &srcStack, std::stack<int> &dstStack); This operation copies the elements of srcStack in the same order onto dstStack. Consider the following statements: Int main() { Std::stack<int> stack1; Std::stack<int> stack2; … copyStack(stack1, stack2); The function copyStack(stack1, stack2); copies the elements of stack1 onto stack2 in the same order. That is, the top element of stack1 is the top element of stack2, and so on. The old contents of stack2 are destroyed and stack1 is unchanged. Note that std::stack<int> is a C++ standard library stack object type. Complete the following program void copyStack(std::stack<int> &srcStack, std::stack<int> &dstStack) { // check if srcStack is empty -> error message is printed and return // remove all the elements of dstStack // create a temporary stack tempStack for…
