Error while taking array of strings as input

I am trying to take array of string as a input but its giving run time error

    #include<iostream>
    #include<cstdio>
    #include<string>
    using namespace std;

    int main()
    {
        string str[500];
        int n;
        cin>>n;
        for(int i=0;i<n;i++)
            scanf("%s",&str[i]); \\works fine with cin but gives error using scanf
        return 0;
    }

Process terminated with status -1073741510 (0 minute(s), 10 second(s))

works fine with cin but give error if i use scanf

Can some one tell me why its giving such error

what does that error mean and why doesn't it gives error while using cin
