- 2. WHAT IS ACOMPILER? • Translates the entire source code into machine code. • Generates an executable file (.exe). • Execution is fast after compilation. • Example: GCC compiler for C.
- 3.
- 4. PHASES OF COMPILATION •1. Lexical Analysis • 2. Syntax Analysis • 3. Semantic Analysis • 4. Optimization • 5. Code Generation
- 5. WHAT IS ALINKER? • Combines object files and libraries into a final executable. • Resolves external references (e.g., library functions). • Two types: Static linker and Dynamic linker.
- 6. TYPES OF LINKERS •Static Linker: Links all modules at compile time • Dynamic Linker: Links during program execution (runtime)
- 7. WHAT IS ANINTERPRETER? • Translates and executes code line by line. • Does not produce an independent executable. • Execution is slower compared to compiler. • Example: Python Interpreter.
- 8. EXAMPLES OF INTERPRETERS •Python Interpreter • JavaScript Engine (V8, Spider Monkey) • Ruby Interpreter
- 9. WHAT IS ALOADER? • Loads the executable file into memory for execution. • Allocates memory and sets program counter. • Part of the operating system.
- 10. COMPARISON • Compiler:Translates fullprogram executable. → • Interpreter: Executes line by line no executable. → • Linker: Combines object files + libraries final → program. • Loader: Loads program into memory ready to run. →
- 11. CONCLUSION • Compiler:Translates code •Linker: Combines modules • Interpreter: Executes line by line • Loader: Loads program into memory • All four are essential for program execution.
