It s the destructor  This method is called when the instance of your class is destroyed   Stack lt int gt   stack  new Stack lt int gt     do something delete stack     lt - destructor is called here

It s the destructor  it destroys the instance  frees up memory  etc  etc   Here s a description from ibm com   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   See https   www ibm com support knowledgecenter en ssw ibm i 74 rzarg cplr380 htm

That would be the destructor freeing up any dynamic memory

As others have noted  in the instance you are asking about it is the destructor for class Stack    But taking your question exactly as it appears in the title      In c   what does a tilde         before a function name signify    there is another situation  In any context except immediately before the name of a class  which is the destructor context     is the one s complement  or bitwise not  operator  To be sure it does not come up very often  but you can imagine a case like  if   getMask            which looks similar  but has a very different meaning

This is a destructor  It s called when the object is destroyed  out of life scope or deleted    To be clear  you have to use  NameOfTheClass like for the constructor  other names are invalid

It s a destructor  The function is guaranteed to be called when the object goes out of scope
