这行出错：

int *size=fill_array(properties,Max);

编译器显示错误信息如下：
Error] invalid conversion from 'int' to 'int*' [-fpermissive]
代码如下：

#include<iostream>
const int Max=5;

    show_array(properties,size);
    if(*size>0){

        double factor;
        while(!(cin>>factor)){
            cin.clear();
            while(cin.get()!='\n')
                continue;
            cout<<"bad input!";
        }
        revalue(factor,properties,size);
