I came across this rather unusual usage of 'delete'. Just wanted to know if the following line deletes both pointers or only the first?
delete ptr1, ptr2

C library function - remove() The C library function int remove(const char *filename) deletes the given filename so that it is no longer accessible.
Syntax of delete operatordelete pointer_variable; // delete ptr; It deallocates memory for one element.
There's no new / delete expression in C. The closest equivalent are the malloc and free functions, if you ignore the constructors/destructors and type safety.
delete is used for one single pointer and delete[] is used for deleting an array through a pointer. This might help you to understand better.
This is undoubtedly an error. The comma here is the comma operator, not a separator. Only the first pointer, ptr1 is deleted.
The second pointer, ptr2, is just a do-nothing expression.
The delete operator has higher precedence than the , operator, so the expression is parsed as if it were written:
(delete ptr1) , (ptr2) and not as if it were written:
delete (ptr1 , ptr2) If , had higher precedence than delete, then only the second pointer would be deleted.
