C++

 

C++ is a high-level programming language. It is based upon the programming language C. However, C++ has additional features and more advanced components.

In C++, there are expressions and statements. To put it simply, an expression is just an action that needs to be carried out, while a statement is an expression that has been ended by a semicolon. There are three types of statements in the C++ programming language:

1. Declaration Statement
2. Assignment Statement
3. Output Statement

In C++, statements can be grouped together into functions. Every C++ program must contain the function main(). This is because when any C++ program is first opened, it must know what instructions to first carry out. C++ programs always begin execution with the first statement in the main() function. Meanwhile, a C++ program always ends with the last statement in the main() function.

In the C++ language, there can be things called comments. Comments are placed within the characters /* and */. They are used to help clarify things to humans that are reading the language. For example, they could be used to clarify parts of the code or to identify a variable.

There are five major data types in C++ :

1. Char
Char is short for the word character. Char data types represent individual characters, like alphabetical letters and numerical digits. Characters are a single byte, or 8 bits. One bit is one binary digit-a 1 or a 0. The binary system is the basic language of all computers.

2. Int

Int is short for integer. In computer language, an integer value is a machine word. A word is equivalent to either 16 or 32 bits.

3. Float

Float data types are floating point single precision values. This type of data is one word in length.

4. Double

Double data types are floating point double precision values. These are comprised of two words.

5. Long Double

Long double data types are like the data types float and double. It represents floating point extended precision values, and is comprised of three or four words.

C++ is a very advanced programming language. It would be impossible to briefly cover all aspects of this language. If you would like to learn more about C++, I would suggest going to your local library! There are tons of primers and tutorials about how to write in the C++ programming language!
