what is use of for loop after decleration of array
Does it check the size of array or store the array element ?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; }

What happen when this program executeCode:#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; }
I am confused on "for" loop. Why do we use "for" loop after the array declerationCode:#include<stdio.h> int main (void) { int i; int array[4]= {2,2,3,4}; return 0; }
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.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
So the 'for' loop is only used to print array number
What happen when we write this line 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 itCode:intarray[4]= {2,2,3,4};
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.
