处理希腊语单词可能取决于您的平台。
首先,您需要了解文件处理的工作原理。这是我写的:
#include <stdio.h>
#include <string.h>
#include <ctype.h>
#define bufSize 1024 // max lenght of word
// we are going to receive the .txt from cmd line
int main(int argc, char *argv[])
{
FILE *fp;
// Assume file has max 10 words
const size_t N = 10;
// Allocate a 2D array of N rows
// and bufSize columns.
// You can think of it like an array
// of N strings, where every string
// has, at most, bufSize length.
char buf[N][bufSize];
// make sure we got the .txt
if (argc != 2)
{
fprintf(stderr,
"Usage: %s <soure-file>\n", argv[0]);
return 1;
}
// open the file
if ((fp = fopen(argv[1], "r")) == NULL)
{ /* Open source file. */
perror("fopen source-file");
return 1;
}
// we will use that for toupper()
char c;
// counters
int i = 0, j;
while (fscanf(fp, "%1024s", buf[i]) == 1)
{ /* While we don't reach the end of source. */
/* Read characters from source file to fill buffer. */
// print what we read
printf("%s\n", buf[i]);
j = 0;
// while we are on a letter of word placed
// in buf[i]
while (buf[i][j])
{
// make the letter capital and print it
c = buf[i][j];
putchar (toupper(c));
j++;
}
i++;
printf("\ndone with this word\n");
}
// close the file
fclose(fp);
return 0;
}
对于这个 test.txt 文件:
Georgios
Samaras
Γιώργος
Σαμαράς
代码将运行为:
./exe test.txt
Georgios
GEORGIOS
done with this word
Samaras
SAMARAS
done with this word
Γιώργος
Γιώργος
done with this word
Σαμαράς
Σαμαράς
done with this word
如您所见,我可以阅读希腊语单词,但无法将它们转换为大写字母。
一旦你了解了文件处理的方式,你需要使用宽字符来读取带有希腊单词的文件。
所以,只要修改上面的代码,我们就可以得到:
#include <stdio.h>
#include <string.h>
#include <ctype.h>
#include <wchar.h>
#include <wctype.h>
#include <locale.h>
#define bufSize 1024
int main(int argc, char *argv[])
{
setlocale(LC_CTYPE, "en_GB.UTF-8");
FILE *fp;
const size_t N = 15;
wchar_t buf[N][bufSize];
if (argc != 2)
{
fprintf(stderr,
"Usage: %s <soure-file>\n", argv[0]);
return 1;
}
if ((fp = fopen(argv[1], "r")) == NULL)
{
perror("fopen source-file");
return 1;
}
wchar_t c;
int i = 0, j;
while (fwscanf(fp, L"%ls", buf[i]) == 1)
{
wprintf( L"%ls\n\n", buf[i]);
j = 0;
while (buf[i][j])
{
c = buf[i][j];
putwchar (towupper(c));
j++;
}
i++;
wprintf(L"\ndone with this word\n");
}
fclose(fp);
return 0;
}
现在输出是这样的:
Georgios
GEORGIOS
done with this word
Samaras
SAMARAS
done with this word
Γιώργος
ΓΙΏΡΓΟΣ
done with this word
Σαμαράς
ΣΑΜΑΡΆΣ
done with this word
我看到您可能想要创建一个读取单词的函数。如果你需要一个简单的 C 函数示例,可以访问我的伪站点。
至于我上面提到的二维数组,这张图可能会有所帮助:
其中 N 是行数(等于 4),M 是列数(等于 5)。在上面的代码中,N 是N
,M 是bufSize
。我在这里解释更多,您是否还可以找到二维数组动态分配的代码。
我知道你在Windows上。我在Ubuntu中测试了代码。
对于Windows,您可能想好好看看这个问题。
因此,在阅读完以上所有内容并理解它们之后,您可以通过动态内存管理看到您所要求的内容。
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <wchar.h>
#include <wctype.h>
#include <locale.h>
#define bufSize 1024
wchar_t **get(int N, int M);
void free2Darray(wchar_t** p, int N);
int main(int argc, char *argv[])
{
setlocale(LC_CTYPE, "en_GB.UTF-8");
FILE *fp;
const size_t N = 15;
wchar_t** buf = get(N, bufSize);
if (argc != 2)
{
fprintf(stderr,
"Usage: %s <soure-file>\n", argv[0]);
return 1;
}
if ((fp = fopen(argv[1], "r")) == NULL)
{
perror("fopen source-file");
return 1;
}
wchar_t c;
int i = 0, j;
while (fwscanf(fp, L"%ls", buf[i]) == 1)
{
wprintf( L"%ls\n", buf[i]);
j = 0;
while (buf[i][j])
{
c = buf[i][j];
putwchar (towupper(c));
j++;
}
i++;
wprintf(L"\ndone with this word\n");
}
fclose(fp);
// NEVER FORGET, FREE THE DYNAMIC MEMORY
free2Darray(buf, N);
return 0;
}
// We return the pointer
wchar_t **get(int N, int M) /* Allocate the array */
{
/* Check if allocation succeeded. (check for NULL pointer) */
int i;
wchar_t **table;
table = malloc(N*sizeof(wchar_t *));
for(i = 0 ; i < N ; i++)
table[i] = malloc( M*sizeof(wchar_t) );
return table;
}
void free2Darray(wchar_t** p, int N)
{
int i;
for(i = 0 ; i < N ; i++)
free(p[i]);
free(p);
}
请注意,此代码预计可在Linux上运行(在 Ubuntu 12.04 上测试),而不是在 Windows 上(在 Win 7 上测试)。
