The above line is for the pre-processor to process. For example, in the previous chapter, we added following line in the program we created: C++ compilers also include pre-processor which process the files before the compilation starts. For example if you define a function and never invoke it, compiler will not include that function in the executable. It will be helpful to identify the errors if you have ideas how a compiler works. For example compiler will generate different kind of errors and warnings. It is not mandatory to know how compilers compile your source code but if you know it will help you. Now I will give an overview of the compilation process. In the earlier chapters we discussed that we write programs in human readable text and then the compiler converts it to machine readable format so that the CPU can execute the program. ![]() Multiset class and unordered_multiset class (std.C++ Statements, Blocks and Flow Control Statement.C++ Extending Operators for User Defined Types.C++ Modular Programming & Compile Multi File Project.Setting up Environment for C++ Programming.Difference Between C and C++ - The Complete List.Joined: Messages: 37 Likes Received: 7 Trophy Points: 8 Occupation: Software Engineer Location: Kolkata
