Two rather straight foward C++ questions need some answer and explanation.

Please try to use simple C++ code and comment on your logic, these questions are sample questions for my upcoming test and I really need to know how to solve similar problems! Thank you!

1. Assume that Stack is the stack class implemented by a static array, with data type is set to int and stack capacity is 5. Give the contents of the myTop and myArray data members of s after the code segment is executed, or indicate why an error occurs.

Stack s;

for (int i = 0; i < 2; i++)

s.push(2*i);

int i = s.top();

s.pop();

2. Write a function to find the sum of all integers stored in the linked list. The first node is pointed to by a Node pointer "first"

class Node {

public:

int data;

Node * next;

}

Your codes: int sum(Node * first )

{

//Implement the code here.

}
