如何为15000个整数创建一个数组？ [英] how to create an array for 15000 integers?
问题描述
我需要做一个大约15000个整数的数组。
我已经将它声明为无符号字母[13000];
但是编译器说这个太多了。
如何为15000个整数创建数组？
我正在使用Miracle C编译器。
这是我收到的错误：
" c：\documents and settings\david\desktop\asdasdasdasdasdasdasdad22.c：
第6行：太多当地人宣布
''未签名的信[15000]''
中止编译"
I need to do an array with around 15000 integers in it.
I have declared it as unsigned letter[13000];
But the compiler is saying that this is too much.
How can I create an array for 15000 integers?
I am using "Miracle C compiler".
This is the error i am recieving:
"c:\documents and settings\david\desktop\asdasdasdasdasdasdasdad22.c :
line 6: too many locals declared
''unsigned letter[15000]''
aborting compile"
推荐答案
这取决于您的桌面有多少内存。假设你有足够的内存，你可以写：
unsigned int * letter;
if（（letter = malloc（ 15000 * sizeof（int）））== NULL）
返回-1;
" David D'μà£o
"
This will depend on how many memory your desktop has. Assume you have
enough memory, you can write:
unsigned int *letter;
if ((letter = malloc(15000 *sizeof(int))) == NULL)
return -1;

unsigned int * letter;
if（（letter = malloc（15000 * sizeof（int）） ）== NULL）
unsigned int *letter;
if ((letter = malloc(15000 *sizeof(int))) == NULL)
if（（letter = malloc（15000 * sizeof（* letter）））== NULL）
if( (letter=malloc(15000*sizeof(*letter))) == NULL )
返回-1;
return -1;
不是我错误处理的首选。

letter是指向unsigned int的指针，但是你使用sizeof（int）。是的，
他们保证是相同的，但是没有必要依赖
。事实上，写作的首选方式是：
if（（letter = malloc（15000 * sizeof * letter））== NULL）
什么是return -1应该完成？只有当代码在一个返回某个整数（或
最少算术）类型的函数中时才有意义
。如果你假设代码在main（），
之后，那么（a）这是一个不好的假设，（b）从main（）返回-1是
不便携。

我们必须做点什么。这是事情。因此，我们必须这样做。
letter is a pointer to unsigned int, but you use sizeof(int). Yes,
they''re guaranteed to be the same, but there''s no point in depending
on that. In fact, the preferred way to write that is:
if ((letter = malloc(15000 * sizeof *letter)) == NULL)
And what is the "return -1" supposed to accomplish? That makes sense
only if the code is in a function that returns some integer (or at
least arithmetic) type. If you''re assuming the code is within main(),
then (a) that''s a bad assumption, and (b) returning -1 from main() is
not portable.
And please don''t top-post. See the following:

We must do something. This is something. Therefore, we must do this.
