Using a member function Invocation example When invoked on a particular object of type ch_stack, the member functions act on the specified member in that object. The following example illustrates these ideas. If two ch_stack variables ch_stack data, operands; data.reset(); operands.reset();
invoke the member function reset, which has the effect of setting both data.top and operands.top to
EMPTY.
If a pointer to ch_stack ch_stack* ptr_operands = &operands;
ptr_operands -> push('A');
invokes the member function push, which has the effect of incrementing operands.top and setting
operands.s[top] to 'A'.
One last observation: the member function top_of() had its name changed from the previous implementation because of a naming conflict. |
