i do not have any problem here. i solved the problem but i wanted to
know the views of you. please look at it from a newbie's perspective:

problem: define a table with names of months of the year & the number
of days in each month. write out that table. do this using: "a struct &
an array of that struct"

this is the solution i have created:

#include <iostream>
#include <string>

struct month_day {
std::string month;
int days;
};

// creating 12 structures
month_day md0 = {"Jan", 31};
month_day md1 = {"Feb", 28};
.................................................
month_day md11 = {"Dec", 31};

month_day arr_struct[arr_size] =
{md0, md1, md2, md3, md4, md5, md6, md7, md8, md9, md10, md11};

void print_struct_arr(month_day as[])
{
for(int i=0; i < arr_size; ++i)
std::cout << as[i].month << "\t" << as[i].days << "\n";
}


int main() {
print_struct_arr(arr_struct);
}

There is duplication of data here. What for? Couldn't you simply
initialise the array elements using the brace notation?

Besides that, the comments from my response to your post on the array
version apply here, too.

const month_day arr_struct[] =
{
{ "Jan", 31 },
{ "Feb", 28 },
{ "Mar", 31 },

// etc to

{ "Dec", 31 }
};

thanks & Stroustrup said in problem statement that it *must* be an
"array of struct".
