Programming Languages

Programming Languages

1. IDEs (Integrated Development Environment)

   • TREE
     • Translators
       • Translators are compilers and interpreters that convert our high level languages (python, java, C++, etc) into low level languages (binary)
       • Compiler
         • Translates all of the source code at once and creates one executable file
         • Only needed once to create the executable file
         • Returns a list of errors rather than stopping when it finds one.
         • The program runs quickly after a long compiling process
       • Interpreter
         • Translates code one line at a a time
         • Needed every time you want to run the program
         • Returns the first error it finds then stops
         • Runs at a slower pace as it translates the code line by line.
       • Assembler
         • Translates assembly language into machine code.
         • Each CPU requires a unique assembler.
     • Editor
       • Editors allow you to write your code and colour codes your code to make it easier to understand and bug fix. They also allow you to edit your code.
     • Run time environment
       • Run time environment allows you to run and test your code while finding logic errors in your code
     • Error diagnostics
       • Helps you with debugging by telling you where to find your syntax errors and what they are.

2. High level languages

   • Code that is designed to be understood by people so is easier to read, write and modify.
   • C, C++, C#, Python, Java, Javascript, Ruby

3. Low level languages

   • Tricky for humans to read and write but are easier for a computer to run.
   • Assembly language
     • Mnemonics that are created to be understood by different CPUs in different personalised ways
   • Machine code
     • Code that is designed to be read and unserstood by CPUs and CPUs only
