填空题

[说明]
从文件in.dat中读取一篇英文文章存入到字符串数组xx中，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，最后把结果xx输出到文件OUT6.DAT中。
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。
[函数]
#include＜string.h＞
#include＜conio .h＞
#include＜ctype.h＞
#include＜stdio.h＞
char xx[50][80];
int maxline = 0 ; /*文章的总行数*/
int ReadDat (void) ;
void WriteDat (void) ;
void StrOL(void)

char *p1,*p2,t [80];
int i;
for (i=0; i＜maxline; i++)
p1=xx[i];t[0]=0;
while (*p1) p1++;
while (p1＞=xx [i])
while (! isalpha (*p1) ＆＆p1 ! =xx [i]) p1--;
p2 =p1;
while( (1) )p1--;
if (p1==xx [i])
if (isalpha (*p1) p1--;
else if (! isalpha (* (p1+1;)) break;
p2++;
(2) ;
strcat (t,p1+1) ;
strcat (t, " ") ;

strcpy (xx [i] ,t) ;


void main

if( (3) )

while (fgets (xx [i] , 80, fp) ! =NULL)
p=strchr (xx [i] , ’\n’) ;
if(p)*p=0
i++ ;

maxline= (4) ;
fclose (fp);
return 0;

void WriteDat (void)

FILE *fp;

for (i=0; i＜( (5) ) ; i++)
printf("%s\n" ,xx [i]);
fprintf (fp, "%s\n", xx[i]);
