Answer 1

看不懂你这程序，哪里有输出啊，不过看起来挺复杂的，好像是个什么加密算法一样，不过你说的程序输出那个-858993459一般应该是因为你输出的那个变量对应的地址错误了，比如输出a等于-858993459，那么很可能是没有对a赋值，比如我写个输出-858993459的程序你就明白了：
#include<iostream.h>
int main()
{
int i;
cout<<i<<endl;
return 0;
}
这个程序就输出-858993459，因为这里的i根本就没有值，所以 内存中的一个无效值（也可能是以前内存中占有的值吧）。你看看你程序中输出-858993459这个数对应的数的赋值情况就知道了。或许数组越界也可能吧。
#include<iostream.h>
int main()
{
int i[4]={1,2,3,4};
cout<<i[4]<<endl;
return 0;
}这个程序输出不是-858993459，但也是内存中一个数，也是个不知道什么数的数。

Answer 2

你这个输出结果 是随机数 可能是指针没有指向正确的数组位置 或者输出的不是数值而是数组的地址 应该是这方面的错误

程序没粘完，不过我找出错误在哪了。
小女子谢谢各位啦啊！

Answer 5

你程序没写完吧，全都是定义数组啊、、
