求解在编译的最后跑出来MAX was not declared in the scope。
main.cpp
#include <iostream>
#include <iomanip>
#include "vector.h"
using namespace std;
const int MAX = 100;
int main() {
int a1[] = {0,1,2,3,4,5,6,7,8,9};
int s1=sizeof(a1)/sizeof(int);
vector v1(a1,s1);
v1.dump();
vector v2(v1);
v2.set(13,88);
v2.dump();
vector v3(v1);
v3.resize(6);
v3.dump();
vector v4(v1);
v4.resize(15);
v4.dump();
system("pause");
return 0;
}
