把这代码用c语言表示import random def win(): a, b = 100, 100 while a > 0 and b > 0: num = random.randint(0,1) if num == 0: b -= 10 a += 10 else: a -= 20 b += 20 else: if a <= 0: return 1 return 0 sd, n = map(int, input().split(',')) random.seed(sd) cnt = 0 for i in range(n): if win(): cnt += 1 print('A输光的概率为:{:.2%}'.format(cnt/n)) print('B输光的概率为:{:.2%}'.format(1-cnt/n))

这段代码的意思是,定义一个名为 win 的函数,在函数中有两个变量 a 和 b,初始值均为 100。
然后使用一个 while 循环,当 a 和 b 都大于 0 时,循环执行。
在循环内部,使用 random 模块的 randint 函数生成一个 0 到 1 之间的随机整数,如果这个随机整数为 0,则 b 减去 10,a 加上 10;如果这个随机整数为 1,则 a 减去 20,b 加上 20。
当 a 或 b 其中之一小于等于 0 时,退出循环。如果 a 小于等于 0,则返回 1,否则返回 0。
在主函数中,使用 map 函数将输入的两个整数分别赋值给变量 sd 和 n。使用 random 模块的 seed 函数将 sd 作为随机数生成器的种子,然后使用一个 for 循环,循环 n 次,每次循环调用 win 函数,如果函数返回值为 1,则计数器 cnt 加 1。
最后输出 A 的胜率和 B 的胜率,使用 format 函数格式化输出。

需要注意的是,在C语言中,需要引入头文件来使用各种函数和类型,如`<stdio.h>`和`<stdlib.h>`。此外,为了使用随机数,还需要引入`<time.h>`头文件,并使用`rand()`函数来生成随机数。在C语言中,数组的下标从0开始,因此需要将Python代码中的下标进行修改。还需要注意在进行浮点数运算时可能会出现精度问题,因此需要使用`round()`函数来四舍五入取整,并将结果保留到小数点后三位。
