-> Compiler is faster than interpretesbut interpreter gives better error report than compiles. · 7 user ageing Source code - ↓ Preprocessor ↓ modified source code (Pre high level language) Compiler ↓ Targetassemblycode Assembles ↓ relocatable machine code Linker I holder ↓ Target machine code -> The preprocessor convents the source code into modified sauce code (pune high level language) by excluding the macros and excluding the header files. -> the assembles converts this code to relocatable machine code. (The code which doesn't have a memory address) -> The Linker links different objectfiles by putting memory locations tothe relocatable machine code. -> the louder combines all this together and store itin the memory and the targetcode is generated.
