— Yeah i=2,but why does it effect a[1]? i is just a variable right? why would assigning a variable effect array element?

— Array is just a pointer, so when u increment arr[index] u increment array element, not it's copy

— Try to declare

const int arr[5] ... 

instead of
int arr[5] ...

for better understanding


Okay... one more try

int arr[2] = {1, 2};
// u create actually a pointer (int *) named arr, it
//points to a
//memory-area with size sizeof(int) * 2;
int i = ++arr[0];
// here u just write this actually: int i = ++*(arr + 0);
// so u increment variable, that locate at 'arr + 0' address

— Well thanks! that explains 😁

— I ALWAYS get segmentation fault when i try to use 2D arrays or an array of strings. Any idea why?

— Show code

— Int main()
int ele,i,n,q;
int row,column;

int array[100][100];

for(int j=0;j<ele;j++)
for(int k=0;k<q;k++)
return 0;

— Its sort of a 2D array but number of elements in each row is not the same.. the number of elements is the first input in each line which i've taken as ele
