push() ADDS an element to the end of the container, pop() REMOVES the last element at the end of the container. There is no pointer math magic involved. You should try to replicate that behavior in your Stack class. @highwayman, std::stack can adapt a std::vector, std::deque or st...
C++ code to implement stack using c++ class with implementation of PUSH, POP and TRAVERSE operations. Stack with C++ class.
可以看到使用数组来存数,然后定义push, peek, pop三种方法。 delete[] arr; new与delete应该对应,都用[ ]或都不用[ ]。定义arr 时用了[ ],故这里也用 [ ]来删除 (2)测试文件。Main.cpp #include <iostream> #include "ArrayStack.h" using namespace std; int main() { int tmp=0; ArrayStack<int...
Sample Input and Output For a stack of integer, stack<int> st; st.push(4); st.push(5); stack content: 5 <-- TOP 4 st.pop(); //one pop operation performed stack content: 4 <-- TOP st.pop(); //one pop operation performed stack content: empty stack ...
in c++ you can also have a stack data structure (not the "system stack"). A *vector* in c++ lets you do as you said, mess with internal elements, or any element, yet it has push and pop features like a stack too. You can use the vector class as a stack, but its more than ...
