10.18 Draw the stack of activation records for the following Ada program (a) after the first call to procedure b; (b) after the second call to procedure b. Show the control links and the access links for each activation record. (c) Indicate how b is found in procedure c. procedure env is procedure a is procedure b is procedure cis begin b; end c; begin c; end b; begin b; end a; begin a; end env;

can you help me create a c++ program?

Implement in C Programming 9.5.1: LAB: Parsing dates Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substring() function to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3-1-1990. Ex: If the input is: March 1, 1990 April 2 1995 7/15/20 December 13, 2003 -1 then the output is: 3-1-1990 12-13-2003 Use the provided GetMonthAsInt() function to convert a month string to an integer. If the month string is valid, an integer in the range 1 to 12 inclusive is returned, otherwise 0 is returned. Ex: GetMonthAsInt("February") returns 2 and GetMonthAsInt("7/15/20") returns 0. #include <stdio.h> #include <string.h>   int GetMonthAsInt(char *monthString) { int monthInt;   if (strcmp(monthString, "January") == 0) { monthInt = 1; } else if (strcmp(monthString, "February") == 0) {…

Why does the C++ inclusion guard on a library interface file need a unique symbol or name? Assume that the symbol does not need to be unique and then show what happens when two libraries that are to be #included in the same application both use the same symbol. This is an example of proof by contradiction.

Why must the symbol or name in the C++ inclusion guard on a library interface file be unique? In this case, proof by contradiction may be used to postulate that the symbol does not need to be unique and show what occurs when two libraries to be #included in the same application share the same symbol. Example: the programme.

C++ Can someone answer the following code below in C++: Please add to the project a print statement that says how long each version ran in milliseconds please! Version 1 of the process creation hierarchy uses linked lists to keep track of child processes as described in section "The process control block", subsection "The PCB data structure". For the purposes of performance evaluation, the PCBs are simplified as follows: All PCBs are implemented as an array of size n. Each process is referred to by the PCB index, 0 through n-1. Each PCB is a structure consisting of only the two fields: parent: a PCB index corresponding to the process's creator children: a pointer to a linked list, where each list element contains the PCB index of one child process The necessary functions are simplified as follows: create(p) represents the create function executed by process PCB[p]. The function creates a new child process PCB[q] of process PCB[p] by performing the following tasks: allocate a…

A linked list is developed with the following set of nodes in sequence: 25, 40, 66, 38 and 53. The list first node is referred by First reference variable. The second node is referred by P reference variable while the second last node is referred by Q reference variable. Compose Java statements for the following operations: a) Replace the third node value to 55 using all possible reference variables. b) Delete the last node using the shortest path of reference variable. Then deallocate the memory. Shows all steps involved. c) Insert new node with value 99. Make the new node as third node in the list. Shows all steps involved. d) Destroy the linked list.
