Question

I’m trying to define an array of type char

char data[][]

I want to use it to store some data from another array using strcpy()

The problem is I don’t know exactly what is the length and I can’t specify the length in the array, and I’m getting this error:

Error array type has incomplete element type

Here’s the full code:

int bit_to_ascii(const char core[], char data[])
{
      char char_data2[][];

      strcpy(char_data2, core);
      len1 = strlen(char_data2);

}

You either declare it with maximum size possible and acceptable for your case, or use malloc(3) to ask the runtime to dynamically allocate exact amount of memory for you (then release that memory with free(3) when done).
