What is static storage class ?

Static storage class is a type of storage class. Static storage class variables are stored in memory. The default initial value of static storage class variables is 0 (zero), unless they are initialized explicitly.

The scope of static storage class variables is local or blocks scope, and the life time of the variable, persists between different function calls. Static storage class variables are initialized only once.

Ex:

#include<stdio.h>

#include<conio.h>

void increment();

main( )

{

increment( ) ;

increment( ) ;

increment( ) ;

}

void increment( )

{

static int i = 1 ;

printf ( "%d\n", i ) ;

i = i + 1 ;

}

Output: 1
