程序1

```c

include

int main() {

int head, foot, chicken, rabbit;

printf("请输入头的总数和脚的总数: ");

scanf("%d %d", &head, &foot);

rabbit = (foot - 2 * head) / 2;

chicken = head - rabbit;

if (rabbit >= 0 && chicken >= 0 && foot == 4 * chicken + 2 * rabbit) {

printf("鸡的数量为: %d, 兔的数量为: %d\n", chicken, rabbit);

} else {

printf("无解\n");

}

return 0;

}

```

程序2

```c

include

int main() {

int heads, legs, chickens, rabbits;

printf("请输入鸡和兔的头数: ");

scanf("%d", &heads);

printf("请输入鸡和兔的脚数: ");

scanf("%d", &legs);

rabbits = (legs - 2 * heads) / 2;

chickens = heads - rabbits;

if ((legs % 2 != 0) || (rabbits < 0 || chickens < 0)) {

printf("无解\n");

} else {

printf("鸡的数量为: %d, 兔的数量为: %d\n", chickens, rabbits);

}

return 0;

}

```

程序3

```c

include

int main() {

int total_heads, total_feet;

int x, y;

printf("请输入总头数和总脚数: ");

scanf("%d %d", &total_heads, &total_feet);

x = 2 * total_heads - total_feet / 2;

y = total_feet / 2 - total_heads;

if (x >= 0 && y >= 0 && total_feet == 4 * x + 2 * y) {

printf("鸡的数量为: %d, 兔的数量为: %d\n", x, y);

} else {

printf("无解\n");

}

return 0;

}

```

程序4

```c

include

int main() {

int h, f, x, y;

printf("请输入总头数和总脚数: ");

scanf("%d %d", &h, &f);

x = 2 * h - f / 2;

y = f / 2 - h;

printf("总头数为: %d, 总脚数为: %d!\n", h, f);

printf("鸡一共: %d只, 兔子一共: %d只!\n", x, y);

return 0;

}

```

程序5

```c

include

int main() {

int a, b, c, d, m, n;

printf("请输入鸡头、兔头、鸡脚、兔脚的数量: ");

scanf("%d,%d,%d,%d", &a, &b, &c, &d);

if (c % 2 != 0 || d % 2 != 0 || c < 4 * a || d > 4 * b) {

printf("输入的数据是错误的!\n");

return 0;

} else {

n = ((c + d) - 2 * (a + b));

m = (a + b) - n;

printf("兔子的数量为: %d, 鸡的数量为: %d\n", n, m);

}

return 0;

}

```

这些程序都遵循了鸡兔同笼问题的基本数学原理,并通过输入头的总数和脚的总数来计算鸡和兔的数量。如果输入的数据满足问题的条件,程序将输出鸡和兔的数量,否则输出无解。你可以选择其中一个程序,并在C语言的编译器中运行它来求解鸡兔同笼问题。
