Writing strings to dynamically allocated array - c

Question

I keep getting 4 "Passing argument 1 of strcpy makes pointer from integer without a cast" error message each time I am trying to write a string to a dynamically allocated array of strings. I know that it has to do with my strcpy call obviously, and that it's a type mismatch issue somewhere, but I need a little assistance on this please.

Answer 1

From code :
strcpy(arr[counter][index],token);
arr[counter][index] refers to the single character of the array, so please use arr[counter] instead of that (which is pointer to the dynamically allocated block),
so that you can copy the string to that dynamic array.
Adding extra details, if you use strcpy as below,
strcpy(arr[counter][index],token);
Still the copy is done but, not in the correct location,
Suppose arr[counter] holds the address of a char pointer which is 1000.
So strcpy(arr[counter][index],token); will copy the string in the address 1000 + index.
strcpy(arr[counter],token) will copy the string in the address 1000
Hope this is helpful.
