## CS代写|程序设计作业代写algorithm Programming代考|FLOWCHARTING AND ALGORITHMS

A computer program is a sequential set of instructions written in a computer language that is used to direct the computer to perform a specific task of computation.

Observe that the definition demands that any set of instructions must be such that the tasks will usually be performed sequentially unless directed otherwise. Each instruction in the set will express a unit of work that a computer language can support. In general, high level languages, also known as 3GLs, support one human activity at a time. For example, if a computational task involves the determination of the average of three numbers, then it will require at least three human activities, viz., getting the numbers, obtaining the sum of the numbers, and then obtaining the average. The process will therefore require three instructions in a computer language. However, it can be done using two instructions, also: first by obtaining the numbers and second by obtaining the sum and the average.

The objective of programming is to solve problems using computers quickly and accurately.

## CS代写|程序设计作业代写algorithm Programming代考|A problem is something the result of which is not readily available

A problem is something the result of which is not readily available. A set of steps involving arithmetic computation and/or logical manipulation is required to obtain the desired result. There is a law called the law of equifinality that states that the same goal can be achieved through different courses of action and a variety of paths, so the same result can be derived in a number of ways. For example, consider the task of sending a message to one of your friends. There are many ways in which this can be done. First, you can convey the message over the phone if your friend possesses a phone. Second, you can send it by post. Third, you can send it through a courier service. If the message is urgent, then you can try to use the quickest means for sending it. If it is not urgent, then you will choose to send it in the least expensive but most reliable way of doing it. Depending upon the urgency, you will decide the most effective way of doing it. This most effective way is called the optimum way. The different ways of solving a problem are called solution strategies. The optimum way of solving a problem to get the desired result can be achieved by analyzing different strategies for the solution and then selecting the way that can yield the result in the least time using the minimum amount of resources. The selection process will depend on the efficiency of the person and his/her understanding of the problem. He/she must also be familiar with different problem-solving techniques. Determining the set of steps required to solve a given problem is an art. It shows how well a person can arrange a set of steps so that others can follow it. A type of analysis called task analysis is required to reach the solution from a problem definition that states what is to be achieved.

A set of steps that generates a finite sequence of elementary computational operations leading to the solution of a given problem is called an algorithm. An algorithm may be too verbose to follow. The textual description of an algorithm may not be understood quickly and easily. This is why a pictorial representation may be used as a substitute for an algorithm. Such a pictorial representation is called a flowchart. Formally speaking, a flowchart is a diagrammatic representation of the steps of an algorithm. In a flowchart, boxes of different shapes are used to denote different types of operations. These boxes are then connected by lines with arrows denoting the flow or direction to which one should proceed to know the next step. The connecting lines are known as flow lines. Flowcharts may be classified into two categories:
(i) Program Flowchart
(ii) System Flowchart

## CS代写|程序设计作业代写algorithm Programming代考|Program flowcharts

Program flowcharts act like mirrors of computer programs in terms of flowcharting symbols. They contain the steps of solving a problem unit for a specific result.

System flowcharts contain the solutions of many problem units together that are closely related to each other and interact with each other to achieve a goal. We will first focus on program flowcharts.

A program flowchart is an extremely useful tool in program development. First, any error or omission can be more easily detected from a program flowchart than it can be from a program because a program flowchart is a pictorial representation of the logic of a program. Second, a program flowchart can be followed easily and quickly. Third, it serves as a type of documentation, which may be of great help if the need for program modification arises in future.
The following five rules should be followed while creating program flowcharts.

• Only the standard symbols should be used in program flowcharts.
• The program logic should depict the flow from top to bottom and from left to right.
• Each symbol used in a program flowchart should contain only one entry point and one exit point, with the exception of the decision symbol. This is known as the single rule.
• The operations shown within a symbol of a program flowchart should be expressed independently of any particular programming language.
• All decision branches should be well-labeled.
The following are the standard symbols used in program flowcharts:

Flowcharts can be used to show the sequence of steps for doing any job. A set of simple operations involving accepting inputs, performing arithmetic operation on the inputs, and showing them to the users demonstrate the sequence logic structure of a program. The following flowchart shows the steps in cooking rice and then utilizing the cooked rice.
The algorithm for the flowchart about cooking rice is as follows:
Step 1. Take the rice to be cooked.
Step 2. Procure the container.
Step 3. Procure the water.
Step 4. Wash the rice in the water.
Step 5. Put the rice into the container.
Step 6. Pour water into the container.
Step 7. IF WATER LEVEL = I INCH ABOVE THE RICE
THEN GOTO STEP 8
ELSE GOTO STEP 6

• 在程序流程图中只能使用标准符号。
• 程序逻辑应该描述从上到下和从左到右的流程。
• 程序流程图中使用的每个符号应仅包含一个入口点和一个出口点，但决策符号除外。这被称为单一规则。
• 程序流程图符号中显示的操作应该独立于任何特定的编程语言来表达。
• 所有决策分支都应该有良好的标签。
以下是程序流程图中使用的标准符号：
