c++ - My else if statement using a string is not working -

-

this question has answer here:

after amount of time trying else if statement work, doesn't. program keeps returning first one, no matter input. please help.

#include <iostream> #include <string> using namespace std;  string arehap;  int main() {     cout << "are happy?" << endl;     cin >> arehap;     if (arehap == "yes" || "y")     {         cout << "good." << endl;     }     else if (arehap == "no" || "n")     {         cout << "bad." << endl;     }     return 0; }

you should use this:

if (arehap == "yes" || arehap == "y") {     cout << "good." << endl; } else if (arehap == "no" || arehap == "n") {     cout << "bad." << endl; }

when you're using || operator, have compare 2 boolean values. if arehap equal "y", following statement true: arehap == "y". in case computer "understand" if (true || false) { /* smth */} , evaluate true , code want execute run.

java - Ebean enhancement ignores a model -

we using avaje-agentloader enhance our ebeans. ebeans in same package. including loader, agent & base ebean library in our project (via sbt): "org.avaje" % "avaje-agentloader" % "1.1.2", "org.avaje.ebeanorm" % "avaje-ebeanorm" % "4.5.5", "org.avaje.ebeanorm" % "avaje-ebeanorm-agent" % "4.5.2", however, when loader runs enhancement, skips 1 ebean. each ebean annotated @entity , extends com.avaje.ebean.model . there seem no differences between ones enhanced , 1 not. there no includes, or extends, etc. basically, i'm wondering if has run across issue in past, or has insights. things we've tried: specifying actual classes enhanced via serverconfig.setclasses(...) specifying pakages analyse/enhance via serverconfig.addpackage(...) or setpackages(...) not specifying @ , having loader analyse all. we've set break-point @ transformer.transform , bean in questio...
