Why Compilation Error ????????????????????
int pole[100][100];

int main()
{
    int mx1,my1,mx2,my2,l,flag;
      l=0;
      flag= 0;

    int n,m;
    scanf("%d %d",&m,&n);
    scanf("%d %d",&mx1,&my1);
    scanf("%d %d",&mx2,&my2);
    pole[mx1][my1] = pole[mx2][my2] = 2;

    int i;
    for(i=0;i<=n+1;i++)
    {
        pole[0][i] = pole[m+1][i] = 1;
    }
    for(i=0;i<=m+1;i++)
    {
        pole[i][0] = pole[i][n+1] = 1;
    }

    int x=1,y=1,dx=0,dy=1;
    if(pole[x][y]==2) flag = 1;
    pole[x][y] = 1;
    while(1)
    {
        if(pole[x+dx][y+dy]!=1)
        {
            x+=dx; y+=dy;
            if(pole[x][y]==2)
            {
                if(flag) { printf("%d",l+1); return(0); }
                else { flag = 1; l=0; }
            }
            else l++;
            pole[x][y] = 1;
        }
