#include <hstack.h>
int main()
{
hstack<int> A;
int i,N;
for(i=0;i<100;i++) {
A.push(i);
}
for(i=0,N=A.len();i<N;i++) {
int e=A.pop();
printf("%d*%d=%d\\n",i,i,e);
}
return 0;
}
Initializes a new hstack<T> object.
Cleans up an hstack object and all of it''s members.
Clears the hstack object. All elements are flushed from memory.
Returns the current actual length of the stack.
Returns true if the stack is empty.
Pops an element of the stack and assigns it''s value to ''e''. Deletes the popped element.
Peeks the first element of the stack and assigns it''s value to ''e''.
Creates a new element, assigns it the value of ''e'' and pushes the newly created element on the stack.
