These are typically constant values defined in a header file, or on the compiler command line. For example:#if VER < 3 && DEF_OPEN != 0....In this example, two condition variables are used: VER and DEF_OPEN. Eac
The same concept is known in other languages. The specific directive instructions must be supported by the compiler. You can't create custom preprocessing instructions.One of the new directives is a warning pragma, which you can set around a code section to suppress a comma-separated list of ...
IfAmight be null butBandCwouldn't be null if A isn't null, you only need to apply the null-conditional operator toA: C# A?.B.C(); In the preceding example,Bisn't evaluated andC()isn't called ifAis null. However, if the chained member access is interrupted, for example by parent...
As the compiler would replace the symbol of hostNode with the value provided intsconfig.jsonand then substitute that value in the AST. It would then realise that the one of the branches was unreachable at compile time and then collapse the AST branch and only emit the reachable code. 👍29...
letbool=true;// let bool1: Flatten<boolean> = "s"; // Error as string can't be assigned to booleanconsole.log(bool); Output true This way, you can use the conditional types in TypeScript. You can use the generic types, and infer them to make type transformation more flexible. ...
So my first attempt to create an unique project was to use compiler directives (I'm starting to learn about that) and I change my main.c file:main.c: #include code_1.h #include code_2.h #ifdef HARD_1 #include code_1.c #end if #include code_2.c So, by defining or not the ...
