To copy your word, you first have to be sure that it is a valid string (it should, again, end with a '\0'), and make sure it's less than 9 characters long (10 if counting the terminator), because you declared array. Now, each element of your array can hold a string up to 9 characters long (remember, the last one has to be the terminator '\0'). The standard strcpy () function copies a given C-string to another string. If you want to store an entire string inside array, then you'll have to declare your array as an array of arrays of char, like this: char array Write an efficient function to implement strcpy () function in C. Is not an array of strings, it's just an array of characters. Named stars appear as asterisks (*), while unnamed stars appear as dots (.).Ĭhar cmd6 = "show" // displays the names of the couple who owns a pair of stars.Ĭhar cmd7 = "save" // saves the games data into the file system.Ĭhar cmd8 = "load" // loads saved data from universe.Your understanding of the concept of a "string" might be wrong.Ī string in C is nothing else than an array of characters, with the NUL terminator (character '\0') at the end. For each star the command prints the stars serial number, name (if named), and coordinates x, y.Ĭhar cmd3 = "name" // finds closest pair of unnamed stars, and allows player to name the pair.Ĭhar cmd4 = "pairs" // prints list of all pairs of stars that have been named so far.Ĭhar cmd5 = "draw" // used to draw the universe. Takes one integer argument representing the number of stars to be created.Ĭhar cmd2 = "list" // prints list of all stars in the universe. *char cmd1 = "bang" // creates a hypothetical universe comprised of stars only. *CLI FUNCTION (Command line interface implementation)*/ "To start playing, press the RETURN key.\n") "Well, maybe not the part about apple pies -)\n" "And that's exactly what we're going to do.\n" "In order to make an apple pie from scratch, you must first create the universe\n" Star_pairs named_stars //Array of named_universe_max_size, of which each element is a star_pairs structĬhar fbuffer_arr //Frame buffer Stars_single new_stars //Array of new_universe_max_size, of which each element is a stars struct Int star_two_serial //Serial number of second star in pair (integer)ĭouble distance_one_two //Distance (light years) between star one, two (double)Ĭontains all the data about a single universe*/ Int star_one_serial //Serial number of first star in pair (integer) Remember also that C string constants are NOT of type string (they are of type.
