Hi everyone, I'm trying to fill up a table of 10 students as example, how can I do it?

I know just how to make the typedef structure, can any one lend me a help? Thanks !

#define MAX 20

typedef struct date
{
       int day,month,year;
} T_date;

typedef struct student
{
       char first_name[MAX], last_name[MAX];
        float mark;
        T_date birth_day;
} T_student;
