CS2100: Programming languages

1) Scripting vs Programming

Scripting languages: JavaScript, PHP, Python
-> interpreted, do not require compilation
-> Slower generally

Programming Languages: C, C++, Java
-> Compiled
-> Faster generally

In the classification, the environment is more important than the language.
-> We can write C interpreter and use it as a scripting language

2) Imperative Language
Uses a seq of statements to reach a certain goal.
Each statement change the state of the program as it is executed in turn


3) Procedural Language
Type of programming language that specifies a series of well-structured steps and procedures within its programming context to compose a program. Contains a systematic order of statements, functuons and commands to complete a task.

C is an example of both 2) and 3)

4) Timeline of execution (C)
- Editor
Source code
- Compiler
Object code
-Linker + fn libraries and other object codes
Executable code

Using the command
gcc -b Helloworld.c 
displays all details

5) The computer

This is abstraction.
