c++ - 为什么我会换行？

Question

如何让它在同一行？

看起来像:

You see a closed door.
It belongs to house 'Magician's Alley 
5a'. 
Nobody owns this house.

但我希望它看起来像:

You see a closed door. It belongs to house 'Magician's Alley 5a'. Nobody owns this house.

代码:

void House::updateDoorDescription()
{
std::stringstream houseDescription;
houseDescription << "It belongs to house '" << houseName << "'. " << std::endl;

if(houseOwner != 0){
    houseDescription << houseOwnerName;
}
else{
    houseDescription << "Nobody";
}
houseDescription << " owns this house." << std::endl;

HouseDoorList::iterator it;
for(it = doorList.begin(); it != doorList.end(); ++it){
    (*it)->setSpecialDescription(houseDescription.str());
}
}

Answer 1

因为你在做

<< std::endl

这是 endline 并放置一个换行符。去掉这些，它就是你想要的。
