IN LANGUAGE C

Step L First, you need to create a structure game_piece. It should contain the variable, label (char [30]) In addition, the following functions should be defined unction oid game_piece_init default(struct Assign the default string "---" to the game piece's label. me piece piece oid game_ piece_init(struct ame piece piece, char new labprovided. escription Assign the game piece's label with the new label turns the piece's label. har* game_piece_get label(struct me piece piece har game piece to string struct ame piece piece) structs a C string of length 3 from the piece's label ote: this length does not include the null character). If e label is shorter than length 3, then the new string should be the label with spaces appended to make it the orrect length. If the label is longer than 3, then use the irst 3 characters of the label Step 2. You will be creating a structure called game_board in the same code file. The structure will contain a 2-dimensional array called "board" of game piece type and 2 ints, rows and columns. Define the following functions: unction escription tiates the 2-dimensional array "board" to the size oid game_board mit struct ame board* me board, int rows. S"by "columnsspecified by the parameters, then cols) ets the game board's rows and columns values. Then it izes each game piece element of this arrav using the ame piece init default function. So, each piece will ve the default value for its label game board is space_valid(struct The function checks if the parameters row and col are ame board" game board, int row, int alid. If at least one of the parameters "row" or "col" is ol) ess than 0 or larger than the last index of the array (note at the number of rows and columns can be different), en it retum 0 (false). Otherwise it returs1 (true). game_board_add_piece(struct is function should validate that the space specified by ame board" game board, struct ro and col is valid and that the space is not occupied by a ame piece* piece, nt ow, int col) piece. If the game_piece at the space has the default label, e space should be considered not occupied. If the space s both valid and not already occupied, then the space ld be replaced by the parameter "piece" and the ethod should retum 1. Otherwise, retun 0 game board move piecestruct s method should validate that both the src and dest paces are valid and that the dest space is not occupied. If ame board* game board, int conditions pass, then the piece located at (sre row, c col) should be moved to (dest row, destcol). The pace at (src row, src col) should be replaced by the row, int src col, int dest row, int est col) lt game piece. If this method moves the piece, re otherwise return 0 oid game_board print(struct ame board* game board) t prints infonmation of the "board". It should show the list fpieces placed on the board using the e _piece to string function (it shows the first 3 haracters of each piece).
