Derived Data Types

Derived data type is a data type which is derived from primitive data type.
Ex: Array is a collection of homogeneous types of element and it stores elements at adjacent memory locations called as contiguous memory locations.
Syntax:
Data type name_of_array[size];

Ex:
int arr[10];
This array stores ten integer types of element at adjacent memory locations.
arr[0]  arr[1]  arr[2]  arr[3]  arr[4]  arr[5]  arr[6]  arr[7]  arr[9].

\* Write a program to implement array */
#include<conio.h>
#include<stdio.h>
void main()
{
int a[5]={10,20,30,40,50};
int i;
clrscr();
printf("\n\n\tElements in forward direction is -->\n\n");
for(i=0;i<5;i++)
{
printf("\t%d",a[i]);
}
printf("\n\n\tElements in Backward Direction is-->\n\n");
for(i=4;i>=0;i--)
{
printf("\t%d",a[i]);
}
getch();
}

Output-
     Elements in forward direction is -->
      10   20   30   40   50
     Elements in Backward Direction is-->
      50   40   30   20   10
