return c.toLowerCase(); String.fromCharCode(number)函数返回number代表数字的ASCII码。 toLowerCase()用于将大写字母转为小写。 # 返回一个n到m之间的k个互异随机数 function randomKdiffer(n,m,k){ arrayK = []; var i = 0; while (i < k) { a = random(m-n+1)+n; for (var j = 0; ...
生成随机数：使用rand()函数生成随机数。rand()函数返回一个介于RAND_MAX和之间的整数。c复制代码int random_number = rand();生成指定范围的随机数：如果需要生成指定范围内的随机数，可以使用取模和加法运算来实现。例如，生成一个1到100之间的随机数：c复制代码int random_number = rand() % 100 + 1;三、...
rand()%m这个函数是随机产生0到m-1的随机数；比如rand()%10就是随机产生0到9的随机数。
(2) 假设你要随机生成一个在一定范围的数,你能够在宏定义中定义一个random(int number)函数,然后在main()里面直接调用random()函数: 比如:随机生成10个0~100的数: #include<stdio.h> #include<stdlib.h> #define random(x) (rand()%x) void main() { for(int x=0;x<10;x++) printf("%d/n",ran...
(1)如果你只要产生随机数而不需要设定范围的话，你只要用rand()就可以了：rand()会返回一随机数值, 范围在0至RAND_MAX 间。RAND_MAX定义在stdlib.h, 其值为2147483647。(2)如果你要随机生成一个在一定范围的数，你可以在宏定义中定义一个random(int number)函数，然后在main()里面直接调用random(...
