采用类方法返回数组最大的数

#include 
using namespace std;
class Max
{
private:
    int i;
    int a[];
public:
    int accept();
};
int Max :: accept(){
    cout<<"请输入数组长度"<>i;
    int a[i];
    int a1;
    for (int j = 0; j < i; j++){
        cin>>a1;
        a[j] = a1;
    }
    int max = a[0];
    for (int e = 0; e < i; e++)
    {
        if (a[e] > max)
        {
            max = a[e];
        }
    }
    return max;
}
int main(){
    Max mm ;
    int ww = mm.accept();
    cout<<"最大的数是"<
