storing number to array

what is use of for loop after decleration of array

Code:

---

#include<stdio.h>int main (void)
{
        int i;
        int array[4]= {2,2,3,4};
        for(i=0; i<4; i++)
        {
          printf("print array element : %d \n", array[i]);
        }
 
    return 0;


}

Does it check the size of array or store the array element ?

What happen when this program execute

Code:

---

#include<stdio.h>

{
        int i;
        int array[4]= {2,2,3,4};
        for(i=0; i<4; i++)
        {
          printf("print array element : %d \n", array[i]);

I am confused on "for" loop. Why do we use "for" loop after the array decleration

The for loop means you don't have to copy and paste 4 times.

printf("print array element : %d \n", array[0]);
printf("print array element : %d \n", array[1]);
printf("print array element : %d \n", array[2]);
printf("print array element : %d \n", array[3]);

Which is even more important if you don't know how many you need until run time.

So the 'for' loop is only used to print array number

What happen when we write this line ​

Code:

---

intarray[4]= {2,2,3,4};

does it mean's that the array storing four number's and if I want to print them , Then I have to write loop for it

A for loop is used to repeat any sequence of steps.

Okay but still unclear

Yes, the array stores 4 numbers.
How you print them is up to you, but a loop is one common way.
