• Force to reimplement a static function in inherit classes

  - by pacopepe

  Hi, I have a program in C++ with plugins (dynamic libs). In the main program, I want to execute a static function to check if i can create a object of this type. An example without dynamic libs (aren't neccesary to understand the problem): #include "libs/parent.h" #include "libs/one.h" #include "libs/two.h" int main(int argc, char * argv[]) { Parent obj; if (One.match(argv[1])) { obj = new One(); else if (Two.match(argv[1])) { obj = new Two(); } Now, i have a interface class named Parent. All plugins inherit from this class. Ideally, I have a virtual static function in Parent named match, and all the plugins need to reimplement this function. The problem with this code is that i can't do a static virtual function in C++, so i don't know how to solve the problem. Sorry for mi english, i did my best

• Interpreter more strict

  - by pacopepe

  Hi, Today, i lost a lot of time fixing a stupid error in my code. Very simplified, the problem was this: def f(): return 2 2 == f I forgot to write the parenthesis in the sentence, so I compared a pointer function with a number. Ok, my question: Is there any way to change the interpreter to be more stricted with the code? Show more warnings for example... Thanks ^^

• Weird initialization in C

  - by pacopepe

  Hi there, I have this piece of code and i don't know how it works #include <stdio.h> int main(void) { int numero = ({const int i = 10; i+10;}); printf("%d\n", numero); // Prints 20 return 0; } Why if i delete the second part (i+10;), the compiler gets an error? Why are the brackets necessary? Thank you ^^!
