这个问题如何解决？

int *size=fill_array(properties,Max);

#include<iostream>
const int Max=5;
int fill_array(int ar[],int limit);
void show_array(int ar[],int *n);
void revalue(double r,int ar[],int *n);
int main(){
    using namespace std;
    int properties[Max];
    int *size=fill_array(properties,Max);
    show_array(properties,size);
    if(*size>0){
        cout<<"enter revaluation factor:";
        double factor;
        while(!(cin>>factor)){
            cin.clear();
            while(cin.get()!='\n')
                continue;
            cout<<"bad input!";
        }
        revalue(factor,properties,size);
        show_array(properties,size);
    }
    cout<<"Done.\n";
    cin.get();
    cin.get();
    return 0;
}
int *fill_array(int ar[],int limit){
    using namespace std;
    int temp;
    int i;
    for(i=0;i<limit;i++){
        cout<<"enter value #"<<(i+1)<<":";
        cin>>temp;
        if(!cin){
            cin.clear();
            while(cin.get()!='\n')
                continue;
            cout<<"bad input!";
            break;
        }
        else
            if(temp<0)
                break;
        ar[i]=temp;
    }
    return ar+i;
}
void show_array(int ar[],int *u){
    using namespace std;
    for(int i=0;(ar+i)!=u;i++){
        cout<<"property #"<<(i+1)<<":$";
        cout<<ar[i]<<endl;
    }
}
void revalue(double r,int ar[],int *n){
    for(int i=0;(ar+i)!=n;i++)
        ar[i]*=r;
}
