You need to know how that byte array is generated. Do you know which encryption algorithm it is encoded with? WebbIdeally you know the size of the array and can just do this. for (int i = 0; i < sizeof (structure_type) / sizeof (structure_type [0]); i++) If not, you can do this. for (int i = 0; structure_type [i].name != NULL; i++) Your mistake is that a structure is never NULL, NULL is used for pointers only.
