10.12 One linear structure could be more applicable than another.(A) Can a Stack be used to implement a Queue? How complicated are the Queue operations individually? (b) Can a Stack be implemented using a Queue? What level of complexity do the different Stack techniques have? 10.13 Explain how we may effectively build a Queue as a "stack pair," which is a pair of Stacks. (Hint: Picture one stack as being at the front of the queue and the other as being at the back.)
Passing Arguments to a FunctionThe sample program in Example 5.4 shows how the stack frame is used to passarguments to a function.The code simply creates some local stack variables, fillsthem with values, and passes them to a function called callex().The callex() function takes the supplied arguments and prints them to the screen.Example 5.4 Stack and Passing Parameters to a Function/* stack2.c */#include <stdlib.h>#include <stdio.h>int callex(char *buffer, int int1, int int2){/* This prints the input variables to the screen:*/printf("%s %d %d\n",buffer,int1, int2);return 1;}int main(int argc, char **argv){Stack Overflows • Chapter 5 173 char buffer[15]="Hello Buffer"; /* a 15-byte character bufferwith12 characters filled/*int int1=1, int2=2; /* two four-byte integers */callex(buffer,int1,int2); /*call our function*/return 1; /*leaves the main function*/}You need to compile this example in MSVC in a console application inRelease mode or in GCC without optimizations.

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…

Show how to replace the related stack with a single reference in an in-order traversal by removing the accompanying stack. (Hint: The items below the stack top are decided by the stack top; we just need to know the top of the stack.) 12.23 Which additional traversals can be reformulated by substituting a single reference for their Linear structure? How does this modification affect how complicated each iteration is?
12.1-3 Give a nonrecursive algorithm that performs an inorder tree walk. (Hint: An easy solution uses a stack as an auxiliary data structure. A more complicated, but ele- gant, solution uses no stack but assumes that we can test two pointers for equality.)

4.4.2 Queue program Implement a multi-instance version of the linked-list queue. In your program, create 4 queues. Read numbers until you encounter a negative integer input. For every number input, if the number modulo 4 is 0, put the number in the first queue; if the number modulo 4 is 1, put the number in the second queue; if the number modulo 4 is 2, put it in the third queue, and if the number modulo 4 is 3, put it in the fourth queue. When the negative number is input, output all the numbers in the first queue, then all the numbers in the second queue, then all the numbers in the third queue, and then all the numbers in the fourth queue. Detailed specifications: The source file name shall be queueproblem.c. The input shall be integer numbers separated by spaces or newlines. There may be as many as 400 inputs, and it is possible that all input numbers modulo 4 will evaluate to the same value. • The output shall be integer numbers each printed with a %5d format, 12 per output line.…
PP 12.7 Implement an postfix-to-infix translator using stacks. The applicationshould repeatedly read a postfix expression and print the equivalentinfix expression until the user quits. Throw an exception if the postfixexpression entered is invalid.PP 12.8 Implement a class called ReverseWords that uses a stack to output a set of elements input by the user in reverse order.
Q.2. Implement a single linked list. Elements of this linked list should be of integer type, user would provide values as input for elements of this linked list. Which does not allow insertion of duplicate value to the list.
