Notes

What is program and programming language?
*Program usually uses one or more algorithms written in a programming language
* Programming language is like a natural language, but with a very limited set of statements and strict syntax rules. (EX: Java, C++)

A few basic types of instructions appear in programming language:
- Input (get input from the user)
- Output (display data to the user on a monitor or printout)
- Math (perform basic mathematical operations)
- Conditions Execution (check for conditions and executes the appropriate sequence of statements)
- Repetition (perform some sequences of statements repeatedly)

What is a compiler and interpreter?
*Compiler is a program that converts a program written in a programming language into a native language called machine language
*Interpreter takes our program one statement at a time and executes a corresponding set of machine instructions.
-An alternative to a computer is a program.

3 type of syntax error:
- Syntax error
- Runtime error
- Logic error

3 type of programming language:
_ Machine language (1940s)
- Assembly language (1950s)
- High-level language (1960s)
- Very High-level language
- Natural language

1) Machine language
- 1st gen of programming language
- Also known as binary or machine code
- The only language that a computer understands without any translation because this language consists of 0 and 1 which directly correspond to the computers

2) Assembly language
- 2nd gen of programming language
- Also known as symbolic language
- Allows programmers to use symbols or mnemonics (abbreviations) to represent the various machine language
- It uses assembler to translate assembly code into machine code, because computer does not understand Assembly Language.

3) High-Level Language
- 3rd gen of programming language
- Also known as procedural language
- Uses an English language instead of symbols and abbreviations
- Allow programmers to write computer code using instructions resembling everyday spoken language like 'While', 'If', and 'Print'
- Which are then translated into machine language to be executed.

4) Very high-level language
- 4th gen of programming language
- Also known as object-oriented or non-procedural language
Ex: Jave, C++ and visual basic

5) Natural language
- 5th gen of programming language
- Also known as Artificial Intelligence (AI)
- Uses human language to give people more connection with computer
- Allows questions or commands to be framed in more conversational way.
