使用的库函数

rand（）函数 – ->生成0到RAND_MAX（32767）范围内的随机数 ->定义见 / 标题 ->如果我们想将-m到n[n>=m]范围内的随机数分配给变量var，那么使用- var=m+（rand（）%（n–m+1））； ->此函数是一个运行时函数。所以在编译之前必须声明-n，m的值，就像我们在编译之前必须声明数组的大小一样。 ->每当你想生成一个随机数时，调用这个函数
time（）函数 ->返回[UTC，1970年1月1日，00:00:00]的秒数 ->定义为时间。h> 标题
srand（种子） ->根据传递给它的种子生成随机数。 ->如果不使用这个函数，我们使用rand（）函数，那么每次运行程序时，都会生成相同的随机数。 ->为了克服上述限制，我们将时间（NULL）作为种子传递。因此，srand（time（NULL））用于在每次程序运行时生成随机值。 ->始终在程序开始时使用此选项，即在int main（）之后{ ->无需在每次生成随机数时调用此函数 ->定义见 / 标题
freopen（“output.txt”，“w”，stdout） ->将所有数据写入（这就是为什么我们将“w”作为第二个参数传递）输出。txt文件（文件必须与程序所在的文件相同）。 ->用于将标准输出重定向到文件。 ->如果输出。在创建txt文件之前，不会在程序所在的同一文件中创建该文件。
fclose（标准输出） ->关闭标准输出流文件以避免泄漏。 ->始终在程序结束时使用此选项，即在int main（）函数中返回（0）之前。
