一个简单的大数阶乘问题,程序运行结束会出现内存错误,请高手指点~~

会出现这种错肯定是数组越界了

for(i = 0;i< ARR_LEN;i++)
        array[i] = -1;
      array[i] = 1;//这句有问题,执行结果array[199]=1;

LS的名字居然与我如此之像.

for(i = 0;i< ARR_LEN;i++)
        array[i] = -1;
      array[i] = 1;
在这里你的i已指向数组尾了吧，不需要重置i吗？
如i=0;?
没细看，应该在这吧，后面好像看到用到了数组array
     for(j = 2;j <= value;j ++)
     {   
        while(array[i] !=-1 || count != 0)    这里用到了i
        {            
           if(array[i] != -1)
           {
               temp = array[i];
               array[i] = (array[i] * j +count) % 10;
               count = (temp * j +count) / 10;
               i --;

           }
           else
           {
              if( count != 0)
              {
                  array[i] = count % 10;
                  count = count / 10;
                  i--;
              }
           }
        }
        i = ARR_LEN;
        count = 0;
     }

       数组一个很重要的问题就是越界问题。

6搂的广告在这里没用的

原来6楼的广告已删，原7楼变成了现6楼

数组越界,错误已找到~谢谢各位的回答~
