添加随机数时遇到问题 [英] Having trouble adding random numbers
问题描述
您好。我正在制作一个数学辅导计划，它生成两个随机的
数字（从1到500）并要求用户添加它们。如何检查
以查看它们是否输入了正确的总数？你如何添加
无论如何生成的随机数？
#include< iostream>
#include< cstdlib>
#include< time>
#include< conio>
使用命名空间std;
int main（）
{
未签名种子;
cout<< 输入种子值： ;
cin>种子;
srand（时间（0））;
cout<< rand（）％500<< endl;
cout<< rand（）％500<< endl;
cout<< rand（）％500 + rand（）％500;
getch（）;
返回0;
}
输入种子值：1

您需要将随机数存储在变量中。一旦他们存储了b $ b，他们就不再是随机的。

同样的方式你可以添加任意两个数字;它们来自哪里无关紧要。
int r（rand（）+ rand（））;

你应该能够从中找出其余部分。
cout<< rand（）％500<< endl;
cout<< rand（）％500 + rand（）％500;

返回0;

Hi. I am working on a math tutoring program which generates two random
numbers (from 1 to 500) and asks the user to add them. How can I check
to see whether or not they put in the correct total?? How do you add
random numbers that are generated anyway??
#include <iostream>
#include <cstdlib>
#include <time>
#include <conio>
using namespace std;
int main()
{
unsigned seed;
cout << "Enter a seed value: " ;
cin >seed;
srand(time(0));
cout << rand()%500 << endl;
cout << rand()%500 << endl;
cout << rand()%500 + rand()%500;
getch();
return 0;
}
Enter a seed value: 1

stored, they''re no longer random.

matter where they came from.

cout << Rand1 << endl;
You should be able to figure out the rest from that.
cout << rand()%500 << endl;
cout << rand()%500 + rand()%500;
getch();
return 0;
}
Enter a seed value: 1
