Nested Structure

As you know though structure we can process data record by record that is why structure is called user defined data type. In some specific case you nested structure where a structure is inside of a structure. For example when process a student record with their dob. Take a look on following example.

#include<stdio.h>

#include<conio.h>

#include<string.h>

typedef struct s

{

    int roll;

    char name[10];

    struct d

    {

         int dd,mm,yy;

    }dob;

}student;

Static Variable

Static Variable

A static variable initialize by 0 instead of garbage at the time of declaration. Static variable retain its value in memory till the program is running.

On the other hand auto variable lost its data when function scope pass out . But static variable retain its value whenever  scope get over.

You can trace that how many times a function is being called.

void test()

{

    static int k; /* k will retain its value when function scope goes down */

    printf("\nThis function being called %d times ",++k);

}
