I'm not sure what you're asking. arr[] is obviously an array of some type, and i is presumed to be a variable of some type too, but you don't indicate what type of array arr is or why type of variable i is. If I had an array of integers, and a variable i that was an integer. I would do the following to put i at the first index of arr[]:

int main(){
    int i = 5;   /* an arbitrary value */
    int arr[10];   /* an array of 10 integers */
    arr[0] = i;    /* assign value i (which = 5) to the first index in arr[] */

   return 0;
I hope that helps.

If arr[] = i has a meaning, I don't know what it is. If you have an array arr[] then arr points to the beginning of the array, not arr[]. Similarly, if you are assigning values then you can say arr[n] = i, and also in the declaration you can say int arr[] = {i}, but not arr[] = i.

arr[] = i is not valid c++ as far as i can work out, ive tried to do it by overloading the [] operator but it doesnt work because [] has to have one argument and it cant be a default argument

It'd be useful to know what language is being talked about.

As kev said, it doesn't seem like valid C/C++. In C/C++ you would have a syntax like so:

int arr[] = {i, i2, i3, i4};

Your syntax reminds me somewhat of other languages I know, but none that have exactly that syntax...

Depends on the language, cause in php that would actually add an element to the array. It's cool, though you would need the stupid $ signs.
