c# - Interfaces and Coupling -

-

from design , loose coupling standpoint. idea have interface each class in project might part of composition model?

i have project i'm doing this, i'm getting rather lot of interfaces, in attempt keep things relatively loosely coupled.

without knowing specifics of design, that's how interface segregation principle (pdf) supposed work.

you should provide interface every class may need swap out implementation (i wouldn't create interface each dto, example).

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...
