//referenceTypeObject 和 referenceTypeLocalVariable 都在哪存放? 单看valueTypeStructInstance,这是一个结构体实例,感觉似乎是整块都在栈上。但是字段referenceTypeObject是引用类型,局部变量referenceTypeLocalVarible也是引用类型。 public class ReferenceTypeClass { private int _valueTypeField; public ReferenceTypeClas...
The most immediate example is that you shouldn't return a reference to local memory: 1 2 3 4 5 int& getLocalVariable() { int x; return x; }Once the stack frame containing the memory for getLocalVariable is taken off the stack, then the reference returned by this function will no ...
a single return statement can only return one value from a function. In this chapter, we will see how to overcome this limitation by using call by reference.
