I have a short code to print the month and days in a month. I declared a 
struct including month and days. but it does not work.

Please help me.

#include<iostream>
#include<vector>
using namespace std;

struct year{
char* month;
int day;
};

int main(){

vector<year>arr(("Jan",31),("Feb",28));
vector<year>::iterator iter;
for(iter=arr.begin(); iter!=arr.end(); iter++)
cout<<iter->month<<" "<<iter->days<<endl;
return 0;
}

Hi,

 >How can I initialize an array whose type is a struct?

You aren't initializing an array, you are initializing a std::vector.

You cannot construct a std::vector that way, as you did in your code.  You 
can construct arrays like that (with the appropriate syntax).

For a std::vector, use the push_back method.

Also, "iter->days" should be "iter->day".

HTH,

using std::cout;
using std::endl;
using std::string;
using std::vector;

struct year
{
     year(string const& m, int d)
     : month(m), day(d)
     { }

     string month;
     int day;
};

int main()
{
     vector<year> arr;
     arr.push_back(year("Jan", 31));
     arr.push_back(year("Feb", 28));

     vector<year>::iterator iter;
     for(iter = arr.begin(); iter != arr.end(); ++iter)
         cout << iter->month << " " << iter->day << endl;
}
