Are you new in the field of computer programming? Then it is very important to know and understand the common concepts and principles involved in such field. While computer programming for beginners comes with a certain level of difficulty, it is still achievable especially if you are equipped with the basic principles and concepts.
Writing a program involves storing data as well as manipulating it by means of a series of instructions. Included in the data are time and countable factors such as names, dates, and descriptions. By means of data types, you’ll be able to find out how a data must be stored and used.
Most programming languages such as C, C#, C , Visual Basic, and Java have integral parts which novice programmers need to get acquainted with. Among such parts are:
Wannabe programmers have to understand that variables provide them with momentary storeroom for any information needed while the program is used. Variables also play a great role in moving information from one section of the program to another. There’s also the so-called Local variable which can be accessed or modified by a specified portion of a program and global variables which are accessible to any part of the program.
- Data types
Any computer language comes with data types because they help maintain information contained in the program. However, programming languages have some restrictions on the data types they provide. Among the popular data types are characters, pointers, numbers, and strings. Numbers come in either floating points or integers. String data conceals internals that can be manipulated via exposed functions. Additionally, character data type stocks up numbers, symbols, letters, and spaces while the pointer means a piece of memory which can also be utilized for storing arrays.
Since it is an important part of any programming language, it is advisable that you have a good understanding of the various types of outputs in majority of the computer programming languages. One of the popular types is text output, which provides a simple means of revealing the result of a particular computer program. Graphical output is a bit difficult and it needs higher resolution.
- Testing conditions
These allow you to find out the path through a program by implementing a code with value as the basis. This value, which can be variable, another expression, or constant, is compared against an expression. One example of a testing condition statement is “if”. In case the validations became unsuccessful, many computer languages let you define a chunk of code that needs to be executed using “else” statement.
Aside from the indispensable elements of programming languages, computer programming for beginners also requires you to be familiar of the different language categories which include compiled languages, mark-up languages, and programming languages. It is also wise to have full understanding of the general principles and concepts behind each and every programming language. All of these factors are very much useful in helping you become an expert in a particular programming language or in computer programming in general.
