Static storage class

[vead]

What happen when we use static storage class in front of variable name

If I use static or if I don't use static in this program, nothing change

What the benefits of static storage class in program

#include<stdio.h>

void loop (void)
{
	 static int count;
	for (count = 0; count < 5; count++)
	{
		printf("Number :  %d \n", count);
	}
}
int main(void)
{  	
    loop();


    return 0;
}

Try this:

#include<stdio.h>
 
void loop (void)
{
     static int count = 0;
     printf("Number :  %d \n", count++);
}

int main(void)
{   
    for(int i = 0; i < 5; ++i)
        loop();
 
 
    return 0;
}

Try this:

int main(void)
{   
    for(int i = 0; i < 5; ++i)
        loop();
 
}

I didn't get your point What is the meaning of those lines why you are incrementing counter in loop function

The point is for YOU to experiment with calling the same code, where the only difference is the use of the static keyword.

In the hope you'll learn something.

TBH, your simple questions have been going on so long now, you're bordering on being a troll.
Seriously, you need to pick up the pace of learning if you ever hope to write a meaningful program.

I did the two experiment. I printed value with static and without static

Program with static

#include<stdio.h>  
void loop (void)
{
     static int count = 0;
     printf("Number :  %d \n", count++);
}
 
int main(void)
{   
    for(int i = 0; i < 5; ++i)
        loop();
    
    return 0;
}

Number : 0
Number : 1
Number : 2
Number : 3
Number : 4

If I write static before variable , so every call of the function number would change.

If I don't write static before variable , so every call of the function number would be 0

#include<stdio.h>
  
void loop (void)
{
     int count = 0;
    printf("Number :  %d \n", count++);
}
 
int main(void)
{   
    for(int i = 0; i < 5; ++i)
        loop();
    
    return 0;
}

Number : 0
Number : 0
Number : 0
Number : 0
Number : 0

Seriously, you need to pick up the pace of learning if you ever hope to write a meaningful program.

I wrote this program

#include <stdio.h>


void loop(void)
{
    int a = 0;
    static int static_a = 0;


    a += 5;
    static_a += 5;


    printf(" \n a = %d, static_a = %d", a, static_a);
}




int main(void)
{
    int i;


    for (i = 0; i < 5; ++i)
    loop();
	return 0;
}

a = 5, static_a = 5
a = 5, static_a = 10
a = 5, static_a = 15
a = 5, static_a = 20
a = 5, static_a = 25

you're bordering on being a troll..

Why do you think that? I do my best to solve problrm

Note: Not all symptoms listed; just the ones I see in a "Help Vampire".
Edit: It might just be the ones I really dislike seeing in a poster.

Typical symptoms include:
Inability to use web search (eg Google) effectively.
Inability to "try it and see", when asking programming questions.
No apparent increase in comprehension after questions are answered.

I did the two experiment. I printed value with static and without static

And what did those experiments tell you? Did they answer your original question?

I wrote this program

Okay, and what did that program prove/disprove?

I understood the difference. I can see in experiment. If I don't use the static before variable then, every function call, the value of variable doesn't change. if the I use the static before variable name, every function call value in variable change

a) What are the advantages and disadvantages of the static version?
b) Can you think of any times you might use static?

[jimblumberg]

c) Can you think of any times you should avoid the use of static?

And these experiments are only dealing with a static variable inside a function.

d) What happens when you use static outside of any function.
e) What happens when you use static with a function it's self?

And lastly you seem to be leaving out a very important aspect of using a static variable inside a function, what is that aspect?
