The Basics You should Know For programming!

For what Programming language used?

A computer programming language is a language used to write computer programs, which involves a computer performing some kind of computation or algorithm and possibly control external devices.

Example: printers, disk drives, robots, and so on.

Basics elements for programming

• History Of Programming Language You want to Learn: Firstly, collect information regarding that programming language you want to learn such as language developed by whom ? , In which year ? , Was developed for which purpose , Demand and scope of the language now-a-days!

• What are keywords? : A keyword is a word that is reserved by a program because the word has a special meaning. Keywords can be commands or parameters. Every programming language has a set of keywords that cannot be used as variable names. Keywords are sometimes called reserved names .For Example: we call Apple to  a fruit which is actually a Apple And for that we have reserved the apple word And we can say apple is keyword for fruits.

• Datatypes: In programming languages, datatype are the elements which tells us which type of data is assigned to them for storing data . A data type provides a set of values from which an expression may takes it’s values . As its name indicates, a data type represents a type of the data which you can process using your computer program. It can be numeric, alphanumeric, decimal, etc.

• Identifiers: Identifier names must differ in spelling and case from any keywords. You create an identifier by specifying it in the declaration of a variable, type, or function. An identifier name should indicate the meaning and usage of the element being referred.

• Operators: An operator in a programming language is a symbol that tells the compiler or interpreter to perform specific mathematical, relational or logical operation and produce final result. Operators allow us to manipulate the variables and constants in the expressions. Operands are the constants or variables which the operators operate upon.

• Loops: programming structure that repeats a sequence of instructions until a specific condition is met. Programmers use loops to cycle through values, add sums of numbers, repeat functions, and many other things.
