Principles Of Procedural Programming Computer Science Essay

Principles Of Procedural Programming Computer Science Essay Procedural programming is the most natural way of telling a computer what to do as the computer processors own language and machine code is procedural. It is also referred as structured or modular programming. Procedural programming is performed by telling the computer what to do and how to do it through a list of step-by-step instructions. Therefore, procedural programming involves procedures, which implies that there are steps that need to be followed to complete a specific task. For example read a number, add 7 or display a specific message. Procedural programming is quite straightforward and efficient as more than often to begin with, the program is written in a common and plain language by applying logic before actually writing the code. The main features of procedural programming is that it is relatively easy to read and write program code and maintain program code as numerous procedures can be debugged separately. Furthermore, large programs are divided into smaller ones and that most of the data is shared and can therefore be reached from any other point within the program. Conclusively, taking into account that the main characteristics of procedural programing being sequential logic, simplicity, easy implementation of compilers and interpreters, ability to make use of the same code in the program by calling it instead of copying, ease with which the program flow can be tracked, ability to be strongly modular or structured, it can definitely be said that procedural programming is an essential stepping stone towards learning further programming skills. 2. Implementing Procedural Programming Solutions. An algorithm can be defined as a set of steps for performing a task that can be written down and implemented. An algorithm details how to start with known information specified in the problem and how to use that information to reach a solution. In this particular task, the following algorithm using pseudo code has been developed a program which will help a small High Street Curry House manage their business operations. Algorithm using pseudo code Show Login and Exit ( Press 1 to Login/ else exit) Request monthly salary and other income Calculate and Display Total Income Request All Personal Expenses ( i.e. college fees/ rent/ food/travel/entertainment/phone bill/ gas bill/electricity bill/ TV license/ council tax/ club membership and charity contribution and any other expenses) Calculate all expenses and display Total Expenses Calculate and Display Balance (Total Income Total Expenses) If Balance is positive display credit amount and if negative display no more funds available.

When 1 is pressed, User is requested to start entering figures for incomes Screenshot 3| Total Income. When all incomes are entered, Total Income is calculated and displayed. Screenshot 4| Input Expenses. User is requested to input figures for all expenses. Screenshot 5| Total Expenses, Positive Balance and Message. Total Expenses is calculated and displayed.

Balance is obtained and if result is negative, No More Funds Available message displayed 4b| Difference between syntax error and semantic error Syntax is the required grammar and punctuation of the language while semantics is all about meaning, that is, what the statements do, what the programs do. Applying the correct syntax is essential as if not done properly, the program wont run. The syntax of a language greatly affects how easy it is to write, read and understand programs. Syntax errors usually occur when program statements do not conform to the rule of the language. Therefore, Syntax errors occur during the parsing of input code, and are the result of grammatically incorrect statements. Some examples of syntax errors are misspelled keywords, unmatched quotation marks, missing semicolon, illegal character in the input, missing operator, two operators in a row, two statements on the same line with no intervening semicolon, unbalanced parentheses, misplaced reserved word etc. Semantic errors occur when the form of the elements in a statement is correct but the elements are not valid for its use. Semantic errors are normally detected at compile time. Semantic errors occur during the execution of the code, after it has been parsed as grammatically correct. These errors have to do not with how statements are constructed, but with what they mean. Regular examples of sematic errors are such things as incorrect variable types or sizes, non-existent variables, subscripts out of range, specifying the wrong number of arguments for a function, using numeric variable name where only character variable is valid and non-existent references.

Leadership in a time of complexity

Introduction A true and effective leader reacts to critical incidents especially in times of stress  and challenge. He sets an example and is clear about the â€Å"rules of the road† and then adheres to them along the journey. Clarity, consensus and intensity are three essential factors for aligning values of leaders with those of the followers. The importance of shared values is that they channel and focus people’s energies and commitments. Leadership during a Crisis Leadership in critical times was clearly seen in the Hurricane Katrina which hit the Gulf Coast. The U.S. government agencies tasked with relief and rehabilitation operations seem to remain in limbo.   One of which is Federal Emergency Management Agency (FEMA), which reportedly delivered a mere 15 percent of the travel trailers and mobile homes that it hurriedly purchased for temporary housing. The Chicago Tribune reported that FEMA ordered 125,000 travel trailers or mobile homes after Katrina struck in order to provide housing for the estimated 600,000 people who have been displaced by that storm and Hurricane Rita, which hit eastern Texas and western Louisiana three weeks later. However, FEMA was only able to install 18,834 travel trailers in Louisiana and Mississippi and 494 more mobile homes in the two states.[1] Repercussions of the Hurricane There were also reports that a year before Hurricane Katrina hit the Gulf Coast, information technology utilized by the Homeland Security Department to support disaster management was so disconnected and inadequate that it was necessary for employees to develop ad hoc alternatives to supplement them. This was revealed by DHS' inspector general in a derisive report. Conclusion Thus, to point our fingers to a single cause or leadership may be overly simplistic.   The slow and inefficient disaster response may properly be viewed as the effect of various factors, including, but not exclusively, the inadequacies of the FEMA officials.[2]   All these spread far and wide, up to the very top of the government and down to the local government officials. It is sad that there was no strong leadership to have prevented this disaster. In sum, we conclude that leaders do not achieve success by themselves. Exemplary leaders enlist the support and assistance of all those who must make the project work. They involve, in some way, those who must live with the results, and they make it possible for others to do good work. BIBLIOGRAPHY Martin, A. Hitches Show in FEMA Trailer Plan. The Chicago Tribune.
