However, it must be noted that data-processing systems and their supporting personnel were actually products that evolved from Word War II. In fact, during this war, pieces of vital military information were needed to be compiled and organized. It required also reliable persons who could place it in a systematic method and store it in a more safety device. Furthermore, some considerable decisions had became so vast and numerous that it was not possible for a normal beings to collect and put them all in a proper systematic order. They needed a technological innovations to store and retrieve those data at anytime they were needed especially in an urgent situation when important decisions must be made. There must be a device that can aid to analyze those information logically- to be used as a powerful reference and create a precise decision especially, during wartime. Consequently, physicists who were working in the national defense with combined effort and skills with those brilliant engineers and technologists that time had able to invent a more sophisticated machines they dreamt to make -- the computers.
Nevertheless, data -processing systems within the ambit of a c programmer jobs are a logical outgrowth of the tools that have helped people handle the informational aspects of our environment for many centuries. One of the first of these tools was the abacus, which is still used in certain Eastern countries. In some respects, it may be said that the telegraph, typewriter, adding machines and calculators were produced to help us gather and organize information. The computer is actually an extension of these devices. The first computer was put to use in order to work out civilian problems was installed by the Bureau of the Census in 1951 and to help compile the data from the 1950 census. This machine was large and complicated, and seemed impractical to design, install, and used for problems of less scope than analysis of the entire population. However, three years later the first computer was installed by a business firm. Since 1954, many thousands of data-processing systems have been installed in government agencies, industrial firms, banks, insurance agencies, educational systems, publishing houses, colleges, and universities, and scientific laboratories. Because the machines are useless until there is someone to implement them, personnel to program and operate the computers have evolved with the data systems themselves.
Broadly speaking, there are two types of c++ jobs on a computer programming career, namely the system programmer and the one who is known as application programmer. It can be noted that System programmer create the code of sophisticated instructions which are commonly known to be 'programs' or 'software.' These programs have the capability to control the whole brain of the computer system that include the center of the processing system unit, as well as the equipments or say, hardware- by which it can transport its code of communications to produce the desired output. These hardware for instance are the terminal ports, printer devices, and other removable disks or disk drives. Moreover, the skilled programmer writes the desired software to perform a specific task. He may opt to have a specialized skills in engineering related programs or may be in some business and science-related programs. Meanwhile, other veteran specialists may be designated chief business programmers and supervise the work of other business programmers. Programmers often work from descriptions prepared by systems analysts, listing in detail the steps the computer must follow to complete a task. In smaller companies, analysis and programming may be handled by the same person, called programmer-analyst.
Being part of the c# jobs, a programmer analyzes the request that is being made of the instrument, obtains from the persons who make the request information about the kinds of results that they want, discovers the kinds of data that will be needed to attack the problem, and plans the way in which the machine will have to respond to produce the information required. The programmer prepares a flow chart to show the steps in sequence that the machine must make. He or she must pay attention to minute detail and instruct the machine in each step of the process. When the program is completed, the programmer tests its working practicality by having it performed on simulated data. If the machine responds according to expectations, actual data will be fed into it and the program will be activated. If the computer does not respond as anticipated, the program will have to be ''debugged,'' or examined for errors that must be eliminated. Finally, the programmer prepares an instruction sheet for the computer operator who will run the program. The programmer's c programming job, then, is concerned with both an overall picture and with minute details. One works from two points of view: from that of the persons who want certain information produced and from that of technological problem-solving. The work is equally divided between meeting the needs of other people and comprehending the capabilities of the machines.
