#include <stdio.h> #include <stdlib.h>  struct date{    int day;    int month;    int year; };  struct calc{    int row;    int col;    char menu_name[20];    char sub_menu_name[20];    struct date dob; };  int main() {     int count = 0, i;     struct calc *my_calc[2];     //here unable understand need resever seprate memory date?    my_calc[0] = (struct calc *)malloc(sizeof(struct calc));      //trying asign date value     for(count; count<2; count++)    {           printf("please enter day: ");            scanf("%d",&my_calc[count]->date.day);         printf("please enter month: ");            scanf("%d",&my_calc[count]->date.month);         printf("please enter year: ");            scanf("%d",&my_calc[count]->date.year);    }     //trying print date value     printf("day: %d\t  month: %d\t   year: %d\n ",my_calc[0]->date.day,my_calc[0]->date.month,my_calc[0]->date.year);     system("pause");     return 0; } 

you declare dob not date. &my_calc[count]->dob.day
