I would structure the code like this: https://code.sololearn.com/c2JzgxXwhJ2j/?ref=app But it is just the way I like things :)

:) Tobias is correct, they both provide the same result in this context I just like portability and I believe functions should be independent as possible. But as I said, earlier, it is just the way I like things

@Valkryion You need to declare a main function as well and call ajoutedeux in that for ajoutedeux to work. Main serves as the entry point for all C++ applications and it is necessary for all C++ programs to have a main function. So the final code will be : #include <iostream> using namespace std; int ajoutedeux(int nr){ cin>>nr; int resultat = nr + 2; cout<<"Le resultat est"<<resultat<<endl; return resultat; } int main() { int nombre; ajoutedeux(nombre); }

It should be int main(int nr) in the place of int ajoutedeux(int nr). The main method is required by the c++ code to work. You should remove your int ajoutedeux and then add int ain in it's place.

I understand, so i always need my main function to call the function that i created.
