Hi,
In simple terms a destructor is a member that implements the actions required to destruct an instance of a class. The destructors enable the runtime system, to recover the heap space, to terminate file I/O that is associated with the removed class instance, or to perform both operations. For better understanding purpose I will compare C++ destructors with C# destructors.

Destructors in REALbasic can be in one of two forms. Each form uses a regular method declaration with a special name (with no parameters and no return value). The older form uses the same name as the Class itself with a ~ (tilde) prefix. The newer form uses the name "Destructor." The newer form is the preferred one because it makes refactoring the class easier.

it is used to destroy the memory space which is occupy dynamically.it is also have the same name as class followed by a difference sign.

when we use the destructor when log time constructor not use .

In simple words it a simple method called when an object is destroyed.

[tylerlongtw]

it is called whever the object is destroyed, which simply means to free all those resources which that object was having, so as to free the allocated memory for that object.

[vikramrandhawa]

Destructors are usually used to deallocate memory and do other cleanup for a class object and its class members when the object is destroyed. A destructor is called for a class object when that object passes out of scope or is explicitly deleted.A destructor takes no arguments and has no return type. Its address cannot be taken. Destructors cannot be declared const, volatile, const volatile or static. A destructor can be declared virtual or pure virtual.

destructer is nothing but it destroys the structure....

[sandeep552]

When we create constructor of a class a destructer is involuntarily created for destroy objects.
