我已经知道这类事情的答案,但是我真的不知道如何在我的代码中实现它们。另外,除非必要,否则我不想使用任何其他功能。
这是我的代码:
int main()
{
unsigned seed;
seed = 1;
srand(seed);
std::string starFox[8];
int x[8];
starFox[0] = "Do a barrel roll!";
starFox[1] = "Try a somersault!";
starFox[2] = "Use bombs wisely!";
starFox[3] = "Something is wrong with the G-diffuser";
starFox[4] = "Can't let you do that, Star Fox";
starFox[5] = "Hey Einstein, I'm on your side";
starFox[6] = "Whoa! help me!";
starFox[7] = "Daddy screamed REAL good before he died!";
for(int i=0; i<8; i++)
{
int y = 0 + rand() % 8;
x[i] = y;
if (x[i-1]!=y || x[i-2]!=y || x[i-3]!=y || x[i-4]!=y || x[i-5]!=y || x[i-6]!=y || x[i-7]!=y)
{//now I need to make a statement that makes sure each number appears once.
std::cout << starFox[y] << "\n";}
}
std::cout << '\n';
return 0;
}
那么,我应该对这段代码进行哪些更改,以使其在每次执行程序时生成随机数?
最佳答案
每次运行时,您都在播种相同的值,因此您将始终获得相同的伪随机序列。尝试这个:
srand(time(0));
