VC++程序运行结果出错 内存不能被读 这又是什么原因啊

Question

之前是出现应用程序错误的对话框，自己试着把程序调来调去改来改去后，现在又出现内存的错误。这到底是什么错误啊，哪位大虾或者有这个经验的帮帮忙。
下面是我写的程序。这是主函数部分。前面的都是复数与矩阵库运算库，即complex类的声明和定义。

Answer 1

int n,i,m,c; 
complex S2,S1,S,S0,a,b,xn,S10; 
这些个变量你先赋个初值看看，会不会你用到的时候还没有值啊

Answer 2

2处地方可能越界，造成这个错误。if(n+m>63)
{
c=n+m-64;        //判断m+n是否超过64
X[n+m]=X[c];
} 
        S1=X[n+m]*b;        //复数部分运算部分 

Answer 3

谢谢楼上几位的帮助，确实是数组那边的问题。我现在改成这样，但是结果却出不来。感觉好像没错吧，怎么就是会出不来呢

Answer 4

为什么结果只有一个<-1.#IND,0>呢，应该是64*64个才对啊 

Answer 5

这个<-1.IND,0>又是什么数据
