Creating software

1. Integrated Development Environment

   • Translator
   • Auto documentation
   • Libraries
   • Build automation
   • Debugger

2. Low-level language

   • Examples
     • Assembly Language
     • Machine language
   • What are the features of low-level language
     • Programs developed using low level languages are fast and memory efficient.
     • Programmers can utilize processor and memory in better way using a low level language.
     • There is no need of any compiler or interpreters to translate the source to machine code
     • There is no need of any compiler or interpreters to translate the source to machine code
     • It can directly communicate with hardware devices.

3. Translators

   • Interpreter
     • It is needed because if the compiler fails to satisfy the software development needs then they can use the interpreter instead.
     • The interpreter: Parse the source code and perform its behaviour directly, Translate source code into some efficient intermediate representation or object code and immediately execute that, Explicitly execute stored precompiled bytecode made by a compiler which is matched with the interpreter Virtual Memory.
   • Compiler
     • It is needed because it allows the user to perform customized task on a machine and it allows us to communicate with hardware.
     • A compiler is a program translating code written in a programming language into another language.

4. High level language

   • What are the features of high-level language?
     • Require translation
     • Portable
     • Easier to read, write and maintain as commands are similar to English
     • Allow access to module libraries
     • Use data types and data structures, selection statements and repetition/iteration constructs
   • Examples
     • FORTRAN
     • COBOL
     • BASIC
     • PASCAL
     • SIMULA
