A computer program is made up of a chain of instructions a computer has to perform. These instructions may come with other important data that's needed to carry out those instructions. Hence, the process of programming involves the defining of the instructions and the data. For you to come up with data for your computer, you should be familiar with computer programming basics and the datas three fundamental elements:
1. Instructions that need to be carried out.
2. Order in which the instructions are to be carried out.
3. Data needed to do the instructions.
The first stage of computer programming basically involves paper processes. In this phase, you don't even need to work using a computer, however if you use a word processor that will enable you to write your work to a disk file rather than in a piece of paper. You need to do this so you can figure out clearly and more specifically, what you want your computer to perform before you begin to instruct the computer to execute it.
Bear in mind that the computer will follow the instructions exactly as given. It can't say what you want; it can rather do what you want it to do. So before your program comes close to a computer, you need to do several steps which include:
- Defining the problem
Before you instruct the computer what to do, you must first be familiar with it. You need to clearly tell the computer what it needs to accomplish or to generate as the outcome of all the activities it will perform.
- Identifying the solution
If you already know what the computer will produce as an end result, you should take a close look at the information you have, and determine the information that you require. There's also a need for you to define the logical procedures, equations, and other methods you have to utilize so you can manipulate the raw input data into the end result you want to achieve.
- Mapping the solution
This stage in computer programming has to be laid out in proper order. Don't forget that the sequence in which actions are used is as vital as the actions themselves. When organizing the solution into the right order, you will be putting choices into consideration.
When you're done defining the problem as well as designing and mapping the solution, the next thing you need to do is to begin with the task of writing the program code into one or a couple of computer language(s). But before you proceed, you must first decide on the possible languages you need to use as well as the particular computer platform.
Usually, computer languages are optimized for various kinds of tasks. It is, hence, important to select first the language that will best suit the task required. Indeed, learning computer programming basics is the first step a wannabe programmer has to arm himself with, especially if he wants to pursue a career in the said field.
