调用方法如下:
#include <iostream> #include "stack.h" int main(int argc, char* argv[]) { CStack stack = 5; stack.push(1); stack.push(2); stack.push(3); stack.push(4); stack.push(5); stack.push(6); int c =0; stack.pop(c); cout << c << endl; stack.pop(c); cout << c << endl; stack.pop(c); cout << c << endl; stack.pop(c); cout << c << endl; stack.pop(c); cout << c << endl; stack.pop(c); cout << c << endl; getchar(); }
