哪里错了?

[xiaorou00]

FILE *fp;

if ((fp = fopen ("1.txt","rb")) == NULL )
{
printf ("error!");
}
else
{
fseek(fp,0l,SEEK_END);
length = ftell(fp);
txt_buff = (unsigned char *) unsigned char[length];
fread( txt_buff, 1, length, fp );
}

strcpy (s,txt_buff);
delete txt_buff;

不是只有new的才delete吗？

[langhaixin]

没有new 那来的delete！

[zeroweb]

txt_buff怎么声明的, new了没有?

[blue_coco]

txt_buff在栈里，不是在堆。

[MountLion]

txt_buff = (unsigned char *) unsigned char[length];
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
txt_buff = new unsigned char[length];

Study.

[blh]

txt_buff = (unsigned char *) unsigned char[length];？？？
txt_buff = new unsigned char[length];

[huflcy]

txt_buff = (unsigned char *) unsigned char[length];
编译能过去？那应该是编译器比较笨，没有提醒你

[xiaorou00]

写错了 !
txt_buff = (unsigned char *)new unsigned char[length];

[huflcy]

int a
char b[a];
我这样写，编译器肯定不会让我过的，变量是不许用来定义数组的
我不清楚你是怎么骗过编译器的，能否告诉我

[xiaorou00]

这样编译是可以通过,不过当读一个文件很大的时候就乱了!

[xiaorou00]

unsigned char *txt_buff;
