实现象棋的程序需要考虑到棋盘、棋子、走法规则等多个方面。下面是一个简单的C语言程序实现下象棋的示例：
#include <stdio.h>
#include <stdbool.h>
// 棋盘大小
#define BOARD_SIZE 10
// 棋子类型
#define CHESS_KING 1 // 将/帅
#define CHESS_ADVISOR 2 // 士
#define CHESS_ELEPHANT 3 // 象
#define CHESS_HORSE 4 // 马
#define CHESS_CHARIOT 5 // 车
#define CHESS_CANNON 6 // 炮
#define CHESS_SOLDIER 7 // 兵/卒
// 棋盘数组

以上是一个基本的象棋程序框架，你可以根据需要进行修改和完善。注意，这只是一个简单的实现，可能存在许多不足之处，需要根据实际情况进行优化和改进。
