数组中有关的报错问题

Question

#include
using namespace std;
int a[10000];
int main()
{
int j = 2;
int a, b;
cin >> a >> b;
for (int i = 0; i < 10000; i++)
{
while (1)
{
int cnt = 0;
for (int k = 2; k < j; k++)
{
if (j%k == 0)
{
cnt++;
break;
}
}
if (cnt == 0)
{

            a[i] = j;
        }
        j++;
        if (cnt == 0)
        {
            break;
        }
    }
}
int cnt1 = 0;
for (int i = a - 1; i <= b - 1; i++)
{
    if (cnt1 == b - a)
    {
        cout << a[i] << endl;
    }
    else
    {
        if (cnt1 % 10 == 9)
        {
            cout << a[i] << endl;
            cnt1++;
        }
        else
        {
            cout << a[i] << " ";
            cnt1++;
        }
    }
}
system("pause");
return 0;

}

为什么代码中我设的变量i都报错了，平时我这样写对的啊。

数组和变量名字重合---a
