Explain the steps to generate machine code from a C/C++ code.
To generate machine code from a C/C++ code, the process involves three steps: preprocessing, compilation, and assembly.
1. Preprocessing: The first step in generating machine code is preprocessing. In this step, the preprocessor scans the C/C++ code and performs tasks such as removing comments, expanding macros, and including header files. The preprocessor directives, indicated by the '#' symbol, are processed to modify the code before compilation.
2. Compilation: Once the preprocessing step is complete, the code is passed to the compiler. The compiler translates the preprocessed code into assembly language, which is a low-level representation of the code. It performs lexical analysis, syntax analysis, and semantic analysis to check for errors and generate an intermediate representation called object code.
3. Assembly: In the final step, the assembly process takes place. The assembler converts the object code, generated by the compiler, into machine code specific to the target architecture. It translates the assembly instructions into binary instructions that the computer's processor can directly execute. The resulting machine code is a series of binary instructions representing the executable program.
By following these three steps, C/C++ code is transformed from its human-readable form into machine code that can be understood and executed by the computer.
