int a[]={3,5,2,6,1,6,43,6,32,1,77};vectorvec(a,a+11);vector::reference v4=*--vec.end

int a[]={3,5,2,6,1,6,43,6,32,1,77};vectorvec(a,a+11);vector::reference v4=*--vec.end
int a[]={3,5,2,6,1,6,43,6,32,1,77};
vectorvec(a,a+11);
vector::reference v4=*--vec.end

int a[]={3,5,2,6,1,6,43,6,32,1,77};vectorvec(a,a+11);vector::reference v4=*--vec.end
将 v4 指向VECTOR最后一个元素的引用
