Question

How to call a destructor explicitly in C++

Answer 1

#include <iostream>

class Test {
public:
    Test(std::string s): str(std::move(s)) { std::cout << "Constructor\n"; }

    ~Test() { std::cout << "Destructor\n"; }

    std::string& getString() { return str; };
private:
    std::string str;
};

int main()
{
    Test s("c++");

    std::cout << s.getString() << "\n";
  
    s.~Test(); 
    
    return 0;
}
     
     
     
     
/*
run:
   
Constructor
c++
Destructor
Destructor
      
*/
