c++类的成员变量的存储位置？

Answer 1

Test * test_ptr = new Test(); allocated on the heap
Test test; on the stack

Answer 2

Test *ptr = new Test;
Test::array is on the heap, ptr itself is on the stack...

Answer 3

It depends on where the class is instantiated

Answer 4

It’s been 15 years and it’s time to use c++11
Smart pointers are safer

//分配在堆上，多了不会爆栈，当然也不能大的太离谱了
auto test_ptr = shared_ptr<Test>(new Test()); 

//在栈上，多了会爆栈的
Test test;
