Programming Languages

1. IDE

   • Examples include IDLE and Pycharm
   • IDE stands for Integrated Development Environments
   • Features of an IDE
     • Editor
       • Auto colour codes key command words, auto indents code, auto completion for code, line numbers.
         • Editor makes it easier to code as you can be more efficient when finding errors with line numbers and auto colour coding for command words.
     • Translators
       • Compiler
         • Translates all of the source code at the same time and creates one executable file.
       • Interpreter
         • Translates and runs the source code one line at a time, but doesn't create one executable file. If it finds an error it stops.
       • Translate the code from high level to a low level language so that the computer can execute the instructions.
       • Assembler
         • A low level language that is readable for humans and computers and is easier to remember.
           • Mnemonics are shortened command words that tell the computer what operation to perform.
     • Run Time Environment
       • A run time environment allows the code to be run within the IDE so that you don't have to compile it to test it.
     • Error Diagnostics
       • Error Diagnostics help to find and fix errors in a program, they tell you the location of the error and often suggest how to fix it.

2. High level programming languages

   • Designed to be understood by humans
   • Examples include python, c++, javascript.

3. Low level programming languages

   • Designed to be understood by the CPU in a computer system.
   • Examples include binary and assembly code.
