In computer programming language, everything from the programming environment to the variables involved must be understood. If you gain programming skills, you can be a real hero in the virtual world. So, learn computer programming for beginners and learn the tips and tricks you need to get ahead in the cyber world.

What is source code in programming language

It is a series of instructions created using Computer Programming Language to perform specific tasks through a computer. So what is the difference between human language and computer language? Well, it's the difference between the real and the virtual world. The introduction to computer program instructions is called a course code.

Computer programming language is known as program source coding. A computer without a program is like coffee without sugar or a morning without sun. Computer programs can contain anywhere from two to millions of command lines. Just as there are multiple languages ​​in the human world, there are also multiple computer programming languages ​​such as Python, C ++, Java, C, Perl, PHP, and Ruby.

There are hundreds of different programming languages. If you want to speak in many languages, the virtual world is the perfect place for you.

Creating Virtual Reality: What Computer Programs Can Do

Computer programs are used in almost everything from films to medicine, defense to agriculture, entertainment to communication. Commonly used computer programs include MS Word, Internet Explorer, and Adobe Photoshop. Computer programs are used from medical examinations to voice communication.

A computer programmer: the man behind the machine

A computer programmer is one who writes or executes computer programs. Different programmers have diverse skills in many types of computer programming languages.

Algorithm: The A to Z of computer programming language

For the computer programming language, a step-by-step process for solving problems or algorithms plays a central role. An algorithm is a finite set of well-defined instructions, and computer programmers frame the algorithm before creating the actual code.

There are standardized ways of creating computer algorithms.

Elements of a computer programming language: the grammar of the language

Computer programming environment

In any programming language, the most important element to examine is the setup of the environment. This serves as the basis for programming. The installation on the PC is used for writing, compiling and running programs.

The setup, which begins with the use of any programming language, consists of a text editor, a compiler and an interpreter. A text editor is used to create the computer program while the compiler converts the program to binary format. An interpreter is required to be able to run the program directly. Examples of text editors are Notepad ++, TextEdit and BBEdit. Programming languages ​​such as Java, Pascal, and C ++ must have their compilers installed before programming in such languages.

Certain programming languages ​​such as Python, Perl, and PHP do not require compilation into a binary format. The program can be read line by line with an interpreter and executed directly without any further conversion.

Basic Syntax: The ABCs of Computer Programming Language

A one-line computer program can be written easily. Complex coding is required to run complicated programs. Different languages ​​differ in their syntax. For example, every C program begins with the main function and is enclosed in curly brackets. The part of the code within the curly brackets is called the program body.

Functions are small program units that are used to perform certain tasks. C programming offers integrated functions. In certain programming languages, subroutines are used instead of a function. Comments are the feature used to make the program understandable and you can use whatever language you want to write them in. In addition to printable characters that are used to prepare programming instructions, there are also spaces, tabs and a new line in the program. Spaces are common to all programming languages.

Most compilers ignore blank lines or lines with spaces and comments. Every single instruction ends in a certain way, e.g. For example, a single statement in C programs ends with a semicolon.

This is how a program works: step by step

A program works in a complex way. For example, a C program uses a C compiler to convert the instruction to binary format. The binary called demo is created and executed. Like any other language, if you don't follow the rules. There is a syntax error. After such an error, the program will not compile.

Data types: The building blocks of computer programs

A data type represents the data type that can be processed with the computer program. This can range from numeric to alphanumeric, decimal, and so on. When a computer program is written to process different types of data, its type should be clearly identified to ensure that the computer understands how different types of data are processed. A keyword is the range of values ​​that can be represented by the data type.

Primitive data types can be used to create more complex data types, known as user-defined data types. Some programming languages ​​do not require a keyword to specify the data type because they are intelligent enough to automatically process a particular data type. An example of such a language is Python.

Variables: The three step path to programming success

Variables: Names for computer locations that are used to store values ​​in a computer program. First you need to create variables with appropriate names and then store values ​​in these two variables. Then stored values ​​are retrieved from these variables and used. Another name for creating variables is declaring variables. Depending on which programming language is used, there are different ways of creating variables within the program.

Characteristics of variables

A variable can only contain a certain type of value. For example, if the variable was defined as an int or char type, it can only store integers or characters. The C programming language requires the creation of variables, but Python does not. The rules of the game are therefore different depending on which computer programming language is used.

  1. Programming languages ​​such as Python, Perl and PHP do not require the data type to be specified at the time of variable creation.
  2. Any name or designation can be assigned to a variable.
  3. Very few programming languages ​​allow variable names to begin with a digit

Once created variables have been created, you can save values ​​in those variables. Using stored values ​​in the variables is the purpose of the entire exercise. With C programming, different types of data can be printed with different percentages and characters.

Different programming languages ​​offer different sets of a reserved keyword. The only rule that they all have in common is that a reserved keyword cannot be used to name variables.

Connecting the dots: operators

The operator in a computer programming language is a symbol that prompts the compiler / interpreter to perform certain mathematical, relational, or logical operations and to achieve end results.

It adds up: arithmetic operators

These are used for mathematical calculations. Arithmetic operators include plus, minus, and such operations, and the operands or values ​​on which these operations are performed.

Comparison operators = Boolean results

Relational expressions are symbols that are used to produce Boolean results; that is, the results are either true or false.

Logical operators: and or not

Logical operators help in making decisions based on certain conditions. The results can be combined from the conditions to produce an end result. There are three basic types of operators: and, or and not.

Decision Making: Choosing the Right Option

As in real life, in the virtual world, decision making involves choosing an option based on certain conditions. A; Programming languages ​​use conditions or decision statements that work based on the following route:

Different programming languages ​​provide different types of decision statements. For example, in the C programming language, an if ... else statement is used when a decision has to be made that requires one of two options to be selected. Another type of statement that is an alternative to if statements when the variable needs to be tested for equality with certain values, where each value is called a case and the switched-on variable is checked for each switch case. A switch is terminated with a break statement.

We go round and round and round: loops

Loops are used to execute one or more instructions a specified number of times. The real hallmark of a high-level computer programming language is that it uses several loops. Repetitive execution of instructions using this effective technique can be extremely beneficial.

There are different types of loops like while loop, do-while loop, to name a few. The break statement is found in the loop to end it, and program control passes to the next statement.

The numbers game: from the simple whole number to the floating point

Each computer programming language has support for different types of numbers, e.g. B. simple integers, floating point numbers, etc. Certain programming languages ​​have built-in math functions such as C. Others such as Python categorize numbers differently into int, long, complex, and float.

Characters: play an important role

Computer programming language is simply through characters that are assigned in character type variables. It is important to note that the character data type can occupy 8 bits of memory. Some characters have a special meaning in many programming languages ​​through an escape sequence.

Arrays: collection of data types

Almost all basic computer programming languages ​​have a concept called an array. This is a data structure in which a collection of elements of each data type can be stored at a fixed size. An array can be thought of as a collection of variables of one kind.

Arrays contain contiguous storage locations, with the lower address corresponding to the first element and the highest address corresponding to the last element. There are one-dimensional arrays. An element is accessed by indexing the array name.

Play along: save more than one character

If more than one character needs to be stored in a variable, strings are used. Strings in C are represented as arrays of characters. Advanced programming languages ​​such as Java provide a character string as a built-in data type so that character strings can be defined here directly against an array of characters.

Function: Actions speak louder than words

A function is a set of organized, reusable code that is used to perform a single related activity and provide better modularity for an application. They also increase the reusability of codes.

One role, many names

  1. In a computer programming language, functions are referred to as procedures, methods, subroutines, and other such labels.
  2. The function includes the header and body in C. In Java, programming is called a method.

One file I / O: The basic fundamentals of computer programming language

A computer file is used to store data in a digital format such as image data, plain text, or other such content. Computer files have different extensions depending on which computer programming language was used. File input or data that we write to the file is translated into the output or what is read from the file.

Conclusion - computer programming language

There are many different types of programming languages ​​including Objective C, C ++, C, and Java to name a few. When choosing a particular language for development, the first and foremost point to consider is the nature of the app's requirements, i.e. whether it is based on a web desktop or a mobile app. Also, developers should consider the type of market that is receiving the language and learning curve for particular languages.

Developers should ideally seek knowledge of web-based languages, as well as languages ​​for desktop-based and mobile platforms, in order to document the history of scripts in the virtual world. Programming is an amazing process through which virtual commands produce real results. In the virtual world, even a semicolon has an effect, similar to any human language. However, only the limits of your programming language determine the limits of your world in virtual reality.
