Random.nextInt()方法,是生成一个随机的int值,该值介于[0,n)的区间,也就是0到n之间的随机int值,包含0而不包含n。 语法 int nextInt() //随机返回一个int型整数 int nextInt(int num) //随机返回一个值在[0,num)的int类型的整数,包括0不包括num nextInt能接受一个整数作为它所产生的随机整数的上限,...

The rand() function, found in the <cstdlib> header, generates a random number. To generate random number between 0 and 1, we use the following code. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 #include <cstdlib> #include <iostream> #include <ctime> int main() { srand(static_cast<un...
