你能举例说明C++中奇怪的单行注释吗？

Question

我写了一个方法来从C++源文件中删除单行注释:

def stripRegularComments(text) {
  def builder = new StringBuilder()
  text.eachLine {
   def singleCommentPos = it.indexOf("//")
   def process = true
   if(singleCommentPos > -1)
   {
    def counter = 0
    it.eachWithIndex 
    { obj,i ->
     if((obj == '\'') || (obj == '"'))
      counter++
     if(i == singleCommentPos)
     {
      process = ((counter % 2) == 1)
      if(!process)
       return
     } 
    }


if(!process)
{
 def line = it.substring(0,singleCommentPos)
 builder << line << "\n"
}
else
{
 builder << it << "\n" 
}


} else {builder << it <<"\n"}}返回builder.toString()}


我测试了它:

println a.stripRegularComments("""
this is a test inside double quotes "//inside double quotes"
this is a test inside single quotes '//inside single quotes'
two// a comment?//other
single //comment
""")


它产生这个输出:

this is a test inside double quotes "//inside double quotes"
this is a test inside single quotes '//inside single quotes'
two
single


有些情况我不见了吗？

    

Answer 1

有趣的是由三字母和线条延续形成的.我个人最喜欢的是:

/??/
* this is a comment *??/
/

Answer 2

// Single line comments can\
actually be multi line.

Answer 3

我想你无法处理

  puts("Test \
    // not a comment");

这也可能会产生问题:

  puts("'"); // this is a comment

Answer 4

您似乎没有处理转义引号,例如:

"Comment\"//also inside string"

与

"Comment"//not inside string"
