the year is considered 2016.But my program does not working for weeks..the value of check variable always remains 0..help please.

What I have tried:

#include <iostream>
#include
#define pii pair<int>
using namespace std;

int main()
{

    long long n;
    string s;
    while(getline(cin,s))
    {
        int len=s.size();
        int number=0;int check=0;

int i=0;
            while(s[i]!=' ')
            {
                int digit=s[i]-'0';
                number*=10;
                number+=digit;
                i++;

            }

            string ss;
            for(;i<len;i++)>
            {
                if(s[i]=='w')
                {
                    break;
                    check=1;
                }


            }
            if(check==1)                 //here value of check is always remains 0
            {                             // what's the problem cann't understand.
                if(number>=5 and number<=7)
                    cout<<"53\n";
                else if(number>=2 and number<=4)
                    cout<<"52\n";
                else
                    cout<<"51\n";
            }
            else{
                if(number<30)
                    cout<<"12\n";
                if(number==30)
                    cout<<"11\n";
                else if(number==31)
                {
                    cout<<"7\n";
                }
            }
           // cout<<ss<<endl;


    }

//           if(row[x-1]==0 and col[y-1]==0)
//            cout<<day<<" ";
//            else  if(row[x-1]==0 and col[y-1]==0 and day==size-1)
