请教如何生成一组随机数

int a[100];
srand((unsigned) time(0));
for (int i = 0;i < 100;++i)
      a[i] = rand();

// This program seeds the random-number generator
// with the time, then displays 10 random integers.
//

#include <iostream>
//#include <cstdlib>
//#include <cstdio>
#include <ctime>

using namespace std;

int Random(int MIN, int MAX);   // generate a random number

int main()
{
    // set the random-number seed with the current time
    srand((unsigned)time(NULL));

    cout << "请输入要产生的随机数的个数：";
    int NUM;
    cin >> NUM;

    cout << "现在开始产生随机数..." << endl;
    int min, max;

    cout << "请输入要产生的随机数的下限：";
    cin >> min;
    cout << "请输入要产生的随机数的上限：";
    cin >> max;

    //generate the random numbers
    int randoms;

    for (int i=0; i<NUM; i++)
    {
        randoms = Random(min,max);
        cout << randoms << "  ";
    }
    cout << endl;
    system("pause");
    return 0;
}

int Random(int MIN, int MAX)
{
    return (((double)rand() / (double)RAND_MAX)*MAX + MIN);
}
我前不久也遇到了同样的问题.
我用的就是上面的代码.不知道合不合你的要求.

rand()%(33-1+1)+1

要是5到33就是33-5+1=29

呵呵.
