Chapter 1

1. The process of making an executable from the source code is called compilation. Compiling a C++ program is a sequence of complex tasks that results in machine code generation. Typically, a C++ compiler parses and analyzes the source code, generates intermediate code, optimizes it, and finally, generates machine code in a file called an object file. An interpreter, on the other hand, doesn't produce machine code. Instead, it executes instructions in the source code line by line.
2. First, pre-processing, and then the compiler compiles the code by parsing it, performing syntax and semantic analysis, after which an intermediate code is generated. After optimizing the generated intermediate code, the compiler generates the final object file (containing machine code), which can then be linked with other object files.
3. A pre-processor is intended to process source files...
