C++ 内存泄漏对象按函数返回

Question

Are there any memory leak? Does the object will be delete automaticly?

int main ()
{
    SomeClass *someObj;
    ...
    someObj = &foo();
    ...
    return 0;
}

SomeClass foo()
{   
    ...
    return SomeClass();
}

Answer 1

There are no leaks because the code is invalid and shouldn't even compile. You can't take the address of a temporary ( &foo() ).
