passing an iterator to a function

[gulHK]

Hello all

Is there anyway I can pass an iterator to a function?

Thanks

What's your problem? You can surely pass an iterator to a function.

Yes,

What's the problem?

Actually passing an iterator also wont do. I have vectors of different struct types. A "space separated" string is stored in one of the struct variables (all of type string) in each vector. I have to remove spaces from the "space separated" string and replace it with a comma to make it a csv string but except at one place i-e I want to keep that substring still a "space separated" string and I have also stored that "space separated" string separately in one of the struct elements.

e-g

element-1"space separated" string part of the string: "abc 123" which is for example the fifth/sixth substring in the example below 
element-2 of vector-structtype-1: "shnd 23j l94 hsi8 abc 123 md38 fhw0 8fdj"
csv element-2 of vector-structtype-1: "shnd, 23j, l94, hsi8, abc 123, md38 fhw0 8fdj"


element-1 of vector-structtype-2: "space separated" string part of the string: "klm 987" which is for example the fifth/sixth substring in the example below 
element-2 of vector-structtype-2: "dnhs j32 49l 8ish klm 987 83dm 0wfh jdf8"
csv element-2 of vector-structtype-2: "dnhs, j32, 49l, 8ish, klm 987, 83dm, 0wfh, jdf8"

The code below works fine but I dont know how to keep that specific substring still a "space separated" string.

void liffe_breach::CSVline(int Count, int ordIDno, string str) // I want this str to be an elements of a specific vector. Is it possible?
{									// because vectors are of different (struct) types
	std::stringstream Brchno;
  	Brchno << Count;
  	
  	std::stringstream IDno;
  	IDno << ordIDno;
  	
  	stringstream ss(str);
  	string word;
  	string cvsLine = "";
  	while ( ss >> word )
        {
  		cvsLine = cvsLine + word + ",";  
      	}
}

You can temporarily replace the spaces you don't want to transform into another character (for example "_"), run your program, and then re-insert the space back in:

Step 0: "shnd 23j l94 hsi8 abc 123 md38 fhw0 8fdj"
Step 1: "shnd 23j l94 hsi8 abc_123 md38 fhw0 8fdj"
Step 2: "shnd, 23j, l94, hsi8, abc_123, md38, fhw0, 8fdj"
Step 3: "shnd, 23j, l94, hsi8, abc 123, md38 fhw0 8fdj"

EDIT: You know, you wouldn't be having all these problems if you were actually modeling your data, instead of always trying to do string operations.
EDIT2: perl (and regexes in general) is much better suited for this task. This is a 3-line perl script.

Is it always the same field that you want to keep the space ? If so,
you can keep a counter to determine whether to keep the space
or put a comma.

    std::stringstream Brchno;
    Brchno << Count;
    
    std::stringstream IDno;
    IDno << ordIDno;
    
    stringstream ss(str);
    string word;
    string cvsLine;
    int field = 0;
    while ( ss >> word )
    {
        cvsLine = cvsLine + word;
        if (field == 4)
            cvsLine += " ";
        else
            cvsLine += ",";

        ++field;
    }
