The preprocessing process scans the source code, makes a preliminary conversion, and generates a new source for the compiler. The preprocessing process can be seen before the source code is processed by the compiler.In the C language, there is no

  The pre-processing process scans the source code and performs initial conversion to generate new source code for the compiler. It can be seen that the preprocessing process processes the source code prior to the compiler. In C language, there is

Preprocessing is the work done prior to the first lexical scan and parsing of the compilation. To be blunt, the preprocessing part is processed before the source file is compiled, and then the processed code is compiled. The advantage of this is

Conditional compilation of pre-processing commands (# ifdef, # else, # endif, # If, etc) Preprocessing is the work done before the first lexical scan and syntax analysis of compilation. To put it bluntly, it is to process the preprocessing part
