下面是一个简单的六子棋下棋策略的 C 语言代码示例:
```c
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define BOARD_SIZE 6
#define EMPTY 0
#define BLACK 1
#define WHITE 2
int board[BOARD_SIZE][BOARD_SIZE];

for (int i = 0; i < BOARD_SIZE; i++) {
for (int j = 0; j < BOARD_SIZE; j++) {
board[i][j] = EMPTY;
}
}
}
void draw_board() {
for (int i = 0; i < BOARD_SIZE; i++) {
printf(" %d ", i + 1);
}
printf("\n");
for (int i = 0; i < BOARD_SIZE; i++) {
for (int j = 0; j < BOARD_SIZE; j++) {
if (j == 0) {
printf("%c", i + 'A');
}

printf(" - ");
} else if (board[i][j] == BLACK) {
printf(" X ");
} else if (board[i][j] == WHITE) {
printf(" O ");
}
}
printf("\n");
}
}

```
这个代码实现了一个简单的六子棋人机对弈游戏。其中,`minimax` 函数实现了 Minimax 算法,`evaluate` 函数实现了评估函数,`computer_move` 函数实现了计算机下棋的策略。你可以根据需要修改这些函数来优化策略。
