错误消息“error: use of deleted function 'std::unique_ptr<_tp, _dp>::unique_ptr(const std::unique_ptr<_tp, _dp>&)'”表明你尝试使用了一个被删除的构造函数,即std::unique_ptr的复制构造函数。由于std::unique_ptr是不可复制的,其复制构造函数被显式地删除,以防止复制操作的发生。 4. 提供可能...
std::cout<<ptrHandle->value_<<std::endl; } int main() { //新建一个智能指针 TestClass *testPtr(new TestClass()); //设置里面的数值 testPtr->value_=10; testPtrFunction(std::unique_ptr<TestClass>(testPtr)); return 0; }修改方案3:用std::move把unique_ptr移交给函数里面的参数,但这样...
