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

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
