Please need help on C++ language. Infix to Postfix) Write a program that converts an infix expression into an equivalent postfix expression. The rules to convert an infix expression into an equivalent postfix expression are as follows: Initialize pfx to an empty expression and also initialize the stack. Get the next symbol, sym, from infx. If sym is an operand, append sym to pfx. If sym is (, push sym into the stack. If sym is ), pop and append all of the symbols from the stack until the most recent left parentheses. Pop and discard the left parentheses. If sym is an operator: Pop and append all of the operators from the stack to pfx that are above the most recent left parentheses and have precedence greater than or equal to sym. Push sym onto the stack. After processing infx, some operators might be left in the stack. Pop and append to pfx everything from the stack. In this program, you will consider the following (binary) arithmetic operators: +, -, *, and /. You may assume that the expressions you will process are error free. Design a class that stores the infix and postfix strings. The class must include the following operations: getInfix: Stores the infix expression. showInfix: Outputs the infix expression. showPostfix: Outputs the postfix expression. convertToPostfix: Converts the infix expression into a postfix expression. The resulting postfix expression is stored in pfx. precedence: Determines the precedence between two operators. If the first operator is of higher or equal precedence than the second operator, it returns the value true; otherwise, it returns the value false.

Module 02 Discussion - Domestic Containment Discuss the concept of \"domestic containment\". How did this concept operate in 1950\'s-1960\'s America? Why was it destined to ultimately fail? Give an example of one of the values present in domestic containment, and explain why it did not apply to the increasingly independent youth culture during the 1960\'s. Please respond to another student\'s post! By. Mr. Miller Domestic containment is a concept promoted by our government after WWII to encourage uniformity in American households. It painted a picture where the father provided the income for the family, the mother stayed home to care for the household, and the children were obedient. The belief was that providing this stable environment would prevent unwanted influences, such as communism, from permeating our society. it was destined to fail because it was a ludicrous concept, that, if anything, probably bred discontent that ultimately evolved into greater acts of protest, particularly with the youth of the era. The government wanted to create a sense of conformity in our society with this, but as the 1960\'s dawned, the younger generations started to question certain aspects of our society. Things like civil rights and our involvement in Vietnam led prompted many protests, and illustrated the discontent that many had with the status quo of our society. One of the values within domestic containment was that women should stay home to take care of the household and raise the children. Women\'s rights became another rallying point in the 1960\'s as a second wave of feminism took hold, with reproductive rights and pay inequality being key issues. These women had spent their lives being told what they could or couldn\'t do, and they were tired of having their lives dictated to them. Solution Concept of domestic containment :- It is a concept promoted after World war 2nd in US to encouratt certain uniformity in households. It promoted discipline within family by a painted picture which shows father who is the head of the family who provides income for the family, mother who takes care of family as a housewife and children who are discipline to the parents.The belief of domestic containment was to showcase a stable environment and motivate others to follow the same and that will.rile out unwanted though or agressions like communism. It destined to ultimately fail.because of change in social economic culture .The youth didnt accept this theory and considered as ludicrous.People started fighting for their rights rather than blindly follow the theories proposed by government. During 1960\'s major protest was from youth and women\'s . As per domestic containment theory women are supposed to help household things and are not supposed to go for work. It create a hindrance to chase their dreams .Also for you they were not supposed to raise voice against government for holding their rights .This theory of domestic containment become ludicrous because of it .

How financial reporting for public companies has changed since the Enron scandal in 2001. Solution Enron Scandal 2001 Enron a global Gas and Energy company incorporated in Omaha Nebraska and once distinguished as the Nation’s 7th largest company. Listed on Forbs Fortune 500 as being among the wealthiest companies listed on the stock exchange. Through this accumulation of “wealth” Enron at one point held a robust market valuation, which was higher other large global companies like AT&T. Many would call Enron a company that was “too big to fail”; this was due to the company’s reported revenue milestone accomplishment of 100 billion dollars. But what made the Enron scandal so compelling was the fact that it brought down accounting giant Arthur Andersen too. It was a truly amazing situation, a conflation of corporate wrongdoing which would change the accounting world forever. Changes In Financial Reporting and Other Changes due to Enron Scandal 2001 SOX includes several gatekeeper provisions: Requiring a company’s board of directors to have an Audit Committee composed solely of independent directors. Making the Audit Committee responsible for the appointment, compensation, and oversight of the outside auditor and for establishing procedures for the confidential, anonymous submission by company employees of concerns about accounting or auditing practices. Creating a new agency, the Public Company Accounting Oversight Board (PCAOB), to strengthen the outside audit function. The PCAOB sets standards involving auditing, quality control, ethics, and audit reports and has authority to inspect, investigate, and discipline registered public accounting firms. Requiring attorneys who practice before the Securities and Exchange Commission (SEC) to report material violations of the securities laws to a company’s chief legal officer or chief executive officer. If those officers do not respond in an appropriate manner, the attorney is then required to report the violations to the Audit Committee of the board or to another committee composed solely of independent directors. Enhance Regulatory Protections Federal and state securities regulators and self-regulatory organizations play an important and necessary role in corporate governance. They wield a broad and powerful array of sanctions, and their enforcement actions serve as a strong deterrent against wrongdoing. The SEC’s enforcement priorities, reflected in public speeches by its Commissioners and staff, help shape corporate conduct. Increase in Regulations after Sarbanes Oxley The Sarbanes-Oxley Act initiated stringent regulations. The Act was composed of sixty-six sections, some long and others short. Each section dealt with a different part of the reporting cycle (Schaeffer, 2006). These sections are contained within eleven titles, primarily dealing with the issue of internal control. The eleven titles of SOX are as follows: Public Company Accounting Oversight Board, auditor independence, corporate respo.

Give the examples of network core devices Give the examples of physical media? Are they network core or network edge devices? What is queuing delay and packet loss? Solution Answer 3: Example of Network core devices: There are many core devices such as gateways, routers, network bridges, modems, networking cables, line drivers, switches, hubs, and repeaters in networks. Gateways : Gateways are also called protocol converters, can operate at any network layer. A gateway is a router in a computer network. Or we can say that, a major key stopping point for the data on its way to or from other networks, because of gateways, we are able to communicate and send data back. Routers : A router is a networking device that can forwards data packets between computer in networks. Routers do perform the traffic controlling or directing functions on the Internet. A data packet is forwarded from one router to another router, through the networks that have the internetwork until it reaches its destination computer or node. Bridge : A network bridge is a device that connects a local area network (LAN) to another LAN that uses the same protocol as Ethernet or token ring or any other. Modems : A modem is a network device or a program, that enables a computer to transmit data over networking cables, for example : telephone or cable lines or any other. Computer informations are stored in form of digital, whereas information transmitted over telephone lines. it is transmitted in the form of analog waves. Answer 4: physical media: It is refers to the physical materials that are used to transmit information in data communications. It is called as physical media because the media is generally a physical object like as copper or glass. that can be touched and felt, and it also has physical properties like as weight, color and thikness. there are many physical devices like as: 1. Twisted pair cables - Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. There Wire are twisted to avoid crosstalk or any interference for instance, electromagnetic radiation from cables, and crosstalk between neighboring pairs. there are two types of Twisted pair cable like as: a. shielded Twisted pair cable b. unshielded Twisted pair cable. 2. Coaxial cables - it is the kind of copper cable used by cable TV companies. it is used in between of antenna and homes and businesses. Coaxial cable is also used by telephone companies. Coaxial cable is also called as coax. it is a type of cable that has an inner conductor surrounded by a tubular insulating layer, an above of that surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. 3. fiber optics:it is medium or technology associated with the transmission of information as light form along a glass or plastic wire or fiber. Fiber optic cables allow to carries much more information than conventional copper wire and is safer in term of.

Identify and describe the needs-based perspectives on motivation. Relate motivation and employee performance. Discuss the nature of creativity and relate it to decision making and problem solving. Describe the types and uses of power in organizations. Define “organization culture” and explain how it affects employee behavior, and understand its historical roots. Solution Ethics are considered as an asset to the workplace and they provide a properly organised working structure for the organisation. Employee relationship and high morals ensure better productivity and efficiency of the organisations while maintaining the cultural diversity of the organisation. Ethics are necessary to maintain a happy working environment which is beneficial for each and every employee inside the organisation to maintain a more specified way of working. Bi implementation of different ethics and code of conduct, level of implementation of different strategies can be easily done as ethics provide a harmonious working environment. It helps in maintaining in ethical position for environment in workplace which directly increases its compatibility towards the society and increases the efficiency of the organisation. Corporate culture is very essential in defining and formulating a strategy for an organisation. According to the organisational culture, dependencies of strategies are changed. Corporate culture define the type of strategies which is needed for the organisation in the meantime. Different aspects of diversity as well as cultural and corporate needs of the organisation effects the formulation of an strategy. Decisions which affect the organisational equity and interferes in the organisations management are usually excluded from strategy formulation different people in the corporate culture also effects the formulation of the strategy and their effect is reflected on the strategies which are created . Motivational theory is divided into the following influencing factors. Mastery goals Buy successfully learning the overall scenario of the specific training programs and determining the needs I had successfully implemented a plant which directly influence the company is over on productivity towards a specific training program.

describe two processes by which evolution can occur. explain why Solution There are plenty of processes are present, which leads to evolution. for example: Mutation, migration, genetic drift, Selection (Natural and artificial) etc. 1. Mutation is the change in the sequence in DNA (herdiatery material of life). An organism\'s DNA affects how it looks, how it behaves, and its physiology — all aspects of its life. So a change in an organism\'s DNA can cause changes in all aspects of its life. it can be beneficial, neutral, or harmful for the organism. 2. Migration, also known as gene flow, is any movement of individual, that carry genetic material from one population to other. For example: pollen being blown to a destination or people migrates to new cities. If gene versions are carried to a population where those gene versions previously did not exist, gene flow can be a very important source of genetic variation..

Develop a structure chart for student asking diploma in university after graduation of Diagram-0. Your structure chart must automate all processes, data flows and data stores shown on Level-0. Your completed structure chart will have at least three layers (one top-layer module, several middle-layer modules, and several third-layer (or leaves) modules, which capture inputs/outputs, interact with data stores or other common subroutines Solution This should be easy, if you have a leveled set of data flow diagrams available. Start with the context diagram, then repeat the following step for as long as possible (that is, as long as processes that are specified by lower level diagrams exist on the diagram you\'ve obtained). Choose a process on your diagram that\'s specified by a lower level data flow diagram, instead of a process specification. ``Cut and paste,\'\' replacing this process by the simpler processes (and any data stores) in the lower level data flow diagram. Since the conservation of flow rule was used if the leveled set of data flow diagrams was correctly prepared, you should be able to ``match up\'\' the data flows to and from the process being replaced, by the data flow diagrams into and out of the processes you\'re adding to replace it. It should now be the case that all the processes on your diagram are refined by process specifications, and not by lower level data flow diagrams. You\'re ready for the next step. Choose this case if the diagram is ``nontrivial\'\' - it includes four or more processes - and it is easy to split it up into pieces that represent ``subsystems,\'\' such that there is virtually no (direct) communication between subsystems, and the entire system works by invoking each of these subsystems, one at a time. In the ``Student Information System\'\' that will eventually follow, we\'ll see that the diagram we start with has this property. In particular, it will include a ``startup\'\' process that can be considered to be one subsystem, which reads system data from a text file, and initializes data areas - and which is actively ony once, when the system is initiated. All the other processes in the system form a subsystem that repeatedly requests and obtains a user\'s command and executes it. This second ``subsystem\'\' is only activated after the first ``subsystem\'\' terminates. While the two subsystems share information indirectly, in the sense that the second subsystem uses the data areas that the first set up, the only direct communication between the two ``subsystems\'\' is the transmission of a control signal from the first subsystem to the second. Transaction Flow A nontrivial data flow diagram exhibits transaction flow if there is one process in the diagram - a transaction center - that results in multiple data streams flowing out of the transaction center. Each of these data streams corresponds to a major subsystem. Typically, each time the transaction center is activated, it responds by triggering activit.

A) How does the ability of the ligand to cross the plasma membrane determine where the receptors for that ligand will be located? B) Compare the signaling transduction pathway of a hydrophobic ligand with that of a hydrophilic ligand. Solution The term ligand means a molecule bind to another molecule usually larger one.In cells a molecule binds to a receptor is called a ligand which alters the shape and ability of the receptor protein and a cascade of events are initiated results in cell signalling.Polar ligands(hydrophilic) are usually large and cannot cross the pasma membrane they usually binds to the protein receptors on the plasma membrane ,short half life and can be stored in vescles.Transported freely through blood plasma and rapid reponse whereas non polar ligands(hydrophobic) cross the membrane and binds to receptors in cytoplasm or nucleus.Half life is long ; cannot be stored so synthesize when needed.Need a carrier to transported through the blood.Response is very slow..
