Question on Logical OR (||)

[ArbolOne]

#define SQLITE_ROW         100  /* sqlite3_step() has another row ready */
#define SQLITE_DONE        101  /* sqlite3_step() has finished executing */


rc = sqlite3_step(stmt);
if (rc != (SQLITE_DONE) || (SQLITE_ROW)){
std::cout << "Error " << rc << std:;endl;
}

having looked at the snip above, can any one tell me why this program would 
display:
                Error 100
??

Thanks!
