Stack is quite simple. Many computer systems have stacks built into their circuitry. They also have machine-level instructions to operate the hardware stack. Stack is(73)in computer systems.
A.useless
B.not important
C.simple but important
D.too simple to be useful
第1题:
有下列程序: #include<iosteram.h> using namespace std; class Stack { public: Stack(unsignedn=10):size(n){rep_=new int [size];top=O;} Stack(Stack&s):size(s.size) { rep_=new int[size]; fo
