im making a project and i was getting an error out of nowhere supposedly so i went into debug mode and couldn’t find the error but the error only occurred in a specific place so i copied the code and ran it and the error repeated. i couldn’t search as to why it was giving an error as far as i know this should work.
in the code below i tried with direct assigning and it worked but i want to know why the pointer dereference one didn’t work.

#include <string.h>
#include <stdio.h>
#include <stdlib.h>

int assign(char**,char*);

int main(){
    char **arr = calloc(9,sizeof(char*));
    char *ele1 = "hello1";

    assign(arr,ele1);
    
    for(int i=0;i<2;i++){
        printf("%sn",arr[i]);
    }
}

int assign(char **arr,char *ele1){
    for(int *i=0;*i<2;(*i)++){
        arr[*i]=ele1;       
     }
    // for(int i=0;i<2;i++){
    //  arr[i]=ele1;        
    // }
}

i commented the first 3 lines in assign function and uncommented the remaining and tried and it worked. here im only assigning 2 values but that shouldnt give any unknown behaviour
