Language processors
2 likes9,627 views
The document describes a programming tool that facilitates tasks such as code writing, storing, and managing, along with additional tools like compilers and debuggers. It explains functions such as syntax error checking, translating programs into machine language, and assembling code from higher-level languages. Additionally, it covers features like debugging, error resolution, and handling repeated code through macro processing.
Language processors
- 2. ● A program that performs tasks, such as translating and interpreting, required for processing a specified programming language. www.eshikshak.co.in
- 3. www.eshikshak.co.in ● Provides facility to write, store and manage code. ● Provides other tools for programming like compiler, debugger, linker etc.
- 4. www.eshikshak.co.in ● Checks the code line by line to find syntax errors. ● If code is error free translate program into machine language (object code). ● Object code is machine dependent.
- 5. ● Interpret one instruction at a time. ● It checks, translate and execute the instruction. ● Does not produce object code. Input Output High level Result of language Interpreter program program execution www.eshikshak.co.in
- 6. ● Translates the assembly language program into machine code. ● It – ○ Reserves space for data ○ Replaces he mnemonic codes by machine code ○ Replaces symbolic addresses by numeric addresses ○ Determines machine representation of constants Input Output Assembly Machine language Assembler language program program www.eshikshak.co.in
- 7. ● Resolves the relative location of instructions and data ● Links libraries with the object and put them together as executable. www.eshikshak.co.in
- 8. ● Inbuilt component of OS. ● Loads program into main memory and prepare them for execution. www.eshikshak.co.in
- 9. ● Used to find logical errors ● Allows you to stop program at any step of execution, check and change the values of different variables. www.eshikshak.co.in
- 10. ● The repeated code (for e.g., UDF) of program is controlled by macro processor. ● It referred each repeated set of code by a name, and replace set of code when that name occurs in a program. www.eshikshak.co.in
