I am trying to search through a vector of strings.  If the string is found, then I store it into a pointer array.  THere can be up to 4 elements in this pointer array.  Could someone provide me with sample code for this?

I think you need something like this:

string *strPtrArray[4];
int index=0;

vector<string> theStrings;
vector<string>::iterator i;

// Somewhere theStrings is filled

for(i = theStrings.begin(); i !=theStrings.end(); i++ )
{
    if (*i=="Some string") {
        strPtrArray[index++] = &(*i);
    }    
}

I think is not exactly the same, although both can be combined.

Hi Jaime

I just thought that the 2 questions refer to the same problem, although written differently.

I have understood this:

This question is related to search a string into a vector of strings.
Refered question is related to mantain a collection of vector of strings to search in.
There is a third question right now: How to pass a null argument to the same function.
