stray 302 error

[v3ga]

I am doing a program to do dfs traversal given the adjacency matrix. My code follows:

#include <iostream>
   #define SIZE 10
   using namespace std;
   bool M[SIZE][SIZE]; 
   int flag[SIZE]; 
   int dfsNum[SIZE], num;       
   int n;                      
   void dfs( int u, int p ) 
   {
       flag[u] = 1;
       dfsNum[u] = num++;
       for( int v = 0; v < n; v++ ) if( M[u][v] && v != p )
       {
           if( flag[v] == 0 ) 
           {

               dfs( v, u );
           }
       }
       flag[u] = 2;
   }
   int main() 
   {
       cout<<"Enter number of vertices\n";
       cin>>n;
       cout<<"Enter adjacency matrix";
       for(int i=0;i<n;i++)
       for(int j=0;j<n;j++)
       cin>>M[i][j];
       for( int i = 0; i < n; i++ ) 
       flag[i] = 0;
       num = 0;
       dfs( 0, ­1 );
       return 0;
   }

Compiling with g++ goves errors:
dfs.cpp:33: error: stray ‘\302’ in program
dfs.cpp:33: error: stray ‘\255’ in program

There's an invisible control character on line 33. Delete the line and rewrite it.

Thanks. It worked
