具有二维数组的链接列表 [英] Linked list with bidimensional array
问题描述
我创建了这个结构：
typedef struct tabela tabela;
struct tabela {
char nome [50];
int nColunas;
int nLinhas;
char nomeColunas [10] [50];
char valores [50] [65];
tabela * next;
} ;
我的问题如下：
我可以成功改变nome [50]，nColunas和nLinhas的价值，
但我似乎无法将字符串插入nomeColunas或
valores。
这是模拟SQL表，nomeColunas [ 10] [50]表示
你可以拥有10个不同的collum名称和50字节的名字长度。
Valores [50] [65]表示你可以拥有50行价值，其名称长度为
50字节。
我的问题是，如何创建一个允许我改变的函数
这两个bidimensio的值nal数组？
提前感谢您的帮助。

为什么不呢？
我的意思是，你做什么，会发生什么？
我假设你已经在常见问题解答中看到了相关的内容，
并且你有一本体面的C书，而且你已经/>
读取其相关部分，因此你知道C字符串是什么和
C'的多维数组是什么真的是。

你应该可以，例如：
strcpy（myTabela.nomeColunas [4]，你好！ "）;
strcpy（myTabela.valores [4]，Goodbye！）;
发布你的代码，我们会试着帮助你弄清楚出了什么问题。

这个小例子怎么样
#include< stdio.h>
#include< string .h>
typedef struct tabela tabela;
struct tabela {
char nome [50];
int nColunas;
int nLinhas;
char nomeColunas [10] [50];
char valores [50] [65] ;
struct tabela * next;
};
int main（int argc，char * argv []）
{
tabela x;
tabela * x_ptr;
x_ptr =& x;
strcpy（x_ptr-> nome，" testname"）;
strcpy（x_ptr-> nomeColunas [0]，" testcol1"）;
strcpy（x_ptr-> nome Colunas [1]，testcol2）;
printf（"％s \ n"，x.nome）;
printf（" ;％s \ n"，x.nomeColunas [0]）;
printf（"％s \ n"，x.nomeColunas [1]）;
返回0;
}

Hi there! I''m having a problem in my program.
i''ve created this structure:
typedef struct tabela tabela;
struct tabela {
char nome[50];
int nColunas;
int nLinhas;
char nomeColunas[10][50];
char valores[50][65];
tabela *next;
};
my problem is the following:
I can sucessfully alter the values of nome[50], nColunas and nLinhas,
but i can''t seem to be able to insert a string into nomeColunas or
valores.
This is to simulate an SQL table, nomeColunas[10][50] indicates that
you can have 10 diferent collum names with a 50 bytes name length.
Valores[50][65] indicates that you can have 50 lines of values with a
50 bytes name length.
My question is, how can i create a function that permits me to alter
the value on these two bidimensional arrays?
Thanks in advance for any help.

I mean, what do you do, and what happens?
I assume you''ve read anything in the FAQ that looked relevant,
and that you''ve got a decent C book to hand, and that you''ve
read its relevant sections, so you know what a C string is and
what C''s "multi-dimensional arrays" really are.

How about this small example
#include <stdio.h>
#include <string.h>
typedef struct tabela tabela;
struct tabela {
char nome[50];
int nColunas;
int nLinhas;
char nomeColunas[10][50];
char valores[50][65];
struct tabela *next;
};
int main(int argc, char *argv[])
{
tabela x;
tabela *x_ptr;
x_ptr=&x;
strcpy(x_ptr->nome, "testname");
strcpy(x_ptr->nomeColunas[0], "testcol1");
strcpy(x_ptr->nomeColunas[1], "testcol2");
printf("%s\n", x.nome);
printf("%s\n", x.nomeColunas[0]);
printf("%s\n", x.nomeColunas[1]);
return 0;
}
