Introduction in C++

What is c+ +?

C++ is a high-level computer programming language.

What is high-level language and low-level language?

High-level language: High-level languages are those languages that are easy to understand for a human being. These languages are nearest to the common human being languages. The high level language code is called source code.

For example C, C++, Java, COBOL etc

Low-level language: Low-level languages are those languages that are easy to understand for the machine. The low-level language code is called object code.

For example: Binary language(0,1).

What is computer programming language?

Computer programming language is a language that is understandable for a computer. For example, all high level and low level languages including c++ are the computer programming languages.

What is a computer program?

A computer program is a set of instruction written in any high level or low-level language and this set of instruction is understandable for the computer.

Note: Program, code, source code and object code all are just the instructions of any computer programming language.

Machine understands low-level language and human beings understand high-level languages more easily, so how these two kinds of languages are compatible with each other?

We write our code in high-level languages like c++ and then different translator software converts this high-level code into low level language code.

What are types of language translators?

  1. Compiler
  2. Interpreter
  3. Assembler

What is Compiler?

The compiler converts the high-level language code into the object code as a whole.

What are advantages of the compiler?

Faster than interpreter

Produce the executable code

What are disadvantages of the compiler?

Code without any error is must to produce the executable file.

What is Interpreter?

The interpreter converts the high-level language code into the object code statement by statement.

What are advantages of the Interpreter?

Easy to debug

Informs about the errors earlier

What are disadvantages of the Interpreter?

Slower than an interpreter.

What is Assembler?

The assembler converts the assembly language code into the object code.

What are advantages of the Assembler?

  • Faster because assembly language is nearest to the hardware and binary language(machine language).
  • The code is easy to understand for the machine as compared to the high-level language code.

What are disadvantages of the Assembler?

The code is difficult to understand for human as compared to the high-level languages.

More is needed to write for a little task.

  1. In this article, differences between high and low level. That is human and computer instruction, then covert with different translator.

  2. c++ is high-level computer programming. the computer programming language is a language that is understandable for a computer for example high level or low-level language including c++ are the computer programming language. there are three types of a language translator.
    compiler
    interpreter
    assembler

  3. Glad to see the programming related questions as my concepts got cleared about the process of code execution after reading answers. I understood the difference between high and low-level languages, how a language translator converts the statements entered by humans into machine language, how three types of translators are different from each other even having the same purpose and also their advantages/disadvantages.

  4. C++is high-level programming language. It is nearest to human. Low-level language is nearest to the computer. A computer program is a set of instructions. There are three types of a language translator. 1)COMPILER
    2)ASSEMBLER 3)INTERPRETER
