Q4 Write a C program to show the storage, default initial value, scope and life of a static storage class variable.

Write a C program to show the storage, default initial value, scope and life of a static storage class variable.

Program: 142

Write a C program to show the storage, default initial value, scope and life of static storage class variables.

Variable Storage Class tells us:

  1. Storage (location)
  2. Default Initial Value of the variable
  3. Scope of the variable
  4. Life of the variable

1. Storage: Where the variable would be stored.

2. Default Initial Value: What will be the initial value of the variable, if initial value is not specifically assigned. (i.e. the default initial value)

3. Scope: What is the scope of the variable: i.e. in which functions the value of the variable would be available.

4. Life: What is the life of the variable: i.e. how long would the variable exist.

Static Storage Class:

Same as Automatic Storage Class but value remains stored in memory when the function no longer active and it default initial value is zero (0).

Storage : Memory
Default Initial Values : Zero
Scope : Local to the block remains within the block in which the variable defined.
Life : Value of the variable persists between different function calls.

#include<stdio.h>
void increment();
int main()
{
    increment();
    increment();
    increment();
    return 0;

}
void increment()
{
    static int i=1;
    printf("%d\n",i);
    i=i+1;
}

Output:
