删除字符串中的空格的问题 [英] problem with removing spaces in the string
问题描述
假设我有这样的字符串：
我有一个字符串\和一个内部string\\\"我想删除
这个字符串中的空格但不在内部字符串中
在上面的字符串中我必须删除空格，但不要在内部
string（\"和一个内部字符串\\\"）。有谁请告诉我怎么做
这个？
问候
Hi,
Suppose I have a string like this:
"I have a string \"and a inner string\\\" I want to remove space in
this string but not in the inner string"
In the above string I have to remove spaces, but not in the inner

没问题。我想你有一个输入，比如
char s [] ="我有一个字符串\"和一个内部字符串\\\"我想要
删除此字符串中的空格但不删除
内部字符串中的空格" ;;
只需在遍历字符串时开始删除空格; <每当你看到'''''暂停空格移除时，当你看到另一个''''''恢复它时，
。别忘了在
结尾处停下来。

No problem. I suppose you have an input like
char s[] = "I have a string \"and a inner string\\\" I want"
" to remove space in this string but not in the "
"inner string";
Just start removing spaces while you walk through the string;
whenever you see a ''"'' suspend the space removal and when you
see another ''"'' resume it. Don''t forget to stop at the end of
the string.

设置一个标志，表明您遇到了第一个分隔符。想想一个
或更多_states_。如果您仍有问题，请搜索有关模式和状态的信息并说明
图表。
Set a flag indicating you have encountered the first delimiter. Think of one
or more _states_. Search for information on modes and states and state
diagrams if you still have trouble.

我这样做了：
char * strrmspace（char * s）
{
char * sptr = s;
char * instr = s;
char * outstr;
int i = 0;
boolean found_quote = FALSE;
outstr =（char *）malloc（strlen（s）+1）;
while（* instr！=''\'''）
{
if（found_quote）
{
outstr [i ++] = * instr;
}
else
{
if（ ！isspace（* instr））
{
outstr [i ++] = * instr;
}
}
if（（* instr ==''"''）&&（instr [-1]！=''\\''）） />
{
found_quote =！found_quote;
}
instr ++;
} / *而* /
outstr [i] =''\ 0'';
（无效）strcpy（s，outstr）;
free（outstr）;
return（sptr）;
} / * strrmspace * /
如果我有一个字符串
char s [] ="我有一个字符串\" \\\"我想删除此
字符串中的空格，但不删除\内部字符串\中的空格" ;;
但这是删除\内部字符串\中的空格当前一个内部字符串中有
反斜杠时，即。 \" \\\"。
我不想删除内部字符串中的空格。我怎么能实现这个呢？
问候
I have done like this:
char *strrmspace (char *s )
{
char *sptr = s;
char *instr = s;
char *outstr;
int i = 0;
boolean found_quote = FALSE;
outstr = (char * )malloc(strlen(s)+1);
while ( *instr != ''\0'')
{
if ( found_quote )
{
outstr[i++] = *instr;
}
else
{
if ( !isspace( *instr) )
{
outstr[i++] = *instr;
}
}
if (( *instr == ''"'') && ( instr[-1] != ''\\''))
{
found_quote = !found_quote;
}
instr++;
} /* while */
outstr[i] = ''\0'';
(void)strcpy(s, outstr);
free (outstr);
return(sptr);
} /* strrmspace */
And if I have a string
char s[] = "I have a string \"\\\" I want to remove space in this
string but not in the \"inner string\" ";
But this is removing spaces in \"inner string\" when there is
backslash in the previous inner string ie. \"\\\".
I don''t want to remove the spaces in the inner strings. How can I
achieve this?
