Why this c++ code is giving me segmentation fault error on runtime?

Consider the code below:

#include <iostream>
using namespace std;

int main()
{
   const int max=500008;
   long long cordx[max],cordy[max];
   char type[max];
   int n;
   cin>>n;
   for(int m=0;m<n;m++)
       cin>>type[m]>>cordx[m]>>cordy[m];
   return 0;
}

This code is giving me a Segmentation Fault error on runtime.
