求助：为数组赋值过后程序出错……

[dugufengwu]

在一个类里面有几个无符号整形变量，一个4维数组，FILE类型指针文件。

在为4维数组赋初值之后，会影响到之后的对类中其他内容的操作，出现错误。

如在给数组赋值成功后，txt文件无法打开。如果注释掉数组赋值代码，txt文件又能够开。

这个问题困扰我一天了，求高人指教。

[就想叫yoko]

贴代码吧
4维数组？
你真厉害

代码来了。问题就在那注释了的4个for循环那。

for ( int tid=0; tid!=5; tid++)
?

[Quote=引用 3 楼 bluewanderer 的回复:]
for ( int tid=0; tid!=5; tid++)
?

大哥，我错了。
在声明那应该是5，写成4了。
找了这么多人看了都没发现，CSDN好地方啊。

没什么可说的,接分.

[3h随然吧]

数组越界呀，类的对象分配的内存在一块，这样使得File指针的值改变了。所以文件打不开
