不能熟练掌握语言的转换

Question

怎么把这个改成c语言惹

#include <iostream>
using namespace std;

    }

            maxsize = sz;
        else
            maxsize = 100;
        data = new datatype[maxsize];
        last = -1;
    }

    bool isempty() { return last == -1 ? true : false; }

    int length() { return last + 1; }

    bool getdata(int i, datatype &x);    //引用

Answer 1

就是简单的增删改查，要用C的语言重写方法，修改输入输出方式。
