请教两个问题(有深度)?
wbcuc 2011-02-18 11:35:56 There’s a variable VAR, how to judge if it is signed or unsigned?
这个问题太抽象,请问如何回答?
Implement the following stack operations with linked list.
• bool push(int aValue); //push parameter to stack
• int pop(); //pop from stack
• int popall(int aValue); //find and pop all elements in stack that equals to
parameter, and return the amount of popped elements.
• int count(); //return the amount of elements in stack
• void empty(); //empty the stack
上面这个问题不知所云,也不知道怎么回答?
