未知题型函数ReadDat()的功能是实现从文件IN2.DAT中读取一篇英文文章存入到字符串数组xx中:请编制函数 StrOL(),该函数的功能是:以行为单位对行中以空格或标点符号为分隔的所有单词进行倒排。最后把已处理的字符串(应不含标点符号)仍按行重新存入字符串数组xx中,最后调用函数WriteDat()把结果xx输出到文件OUT2.DAT中。
例如:原文:YOU He Me
I am a student.
结果: Me He You
student a am I
原始数据文件存放的格式是:每行的宽度均小于80个字符,含标点符号和空格。
请勿改动主函数main()、读函数ReadDat()和写函数WriteDat()的内容。
include <stdio.h>
include <string.h>
include <conio.h>
include <ctypE.h>
char xx[50] [80];
int maxline = 0;/* 文章的总行数 */
int ReadDat (void);
void WriteDat (void);
void StrOL(void)
{
main ( )
{
clrscr ( );
if (ReadDat ())
{
printf('数据文件 IN2.DAT不能打开! /n/007');
return;
}
StrOL ( );
WriteDat ();
}
int ReadDat (void)
{
FILE *fp;
int i = 0;
char *p;
if((fp = fopen('IN2.DAT', 'r')) == NULL) return 1;
while(fgets(xx[i], 80, fp) != NULL)
{
p = strchr(xx [i], '/n');
if(p) *p = 0;
i++;
}
maxline = i;
fclose (rD):
return 0;
}
void WriteDat (void)
{
FILE*fp;
int i;
clrscr ();
fp = fopen('OUT2.DAT', 'w');
for(i = 0; i < maxline; i++)
{
printf('%s/n', xx[i]);
fprintf(fp, '%s/n', xx[i]);
}
fclose (fp);
}
