Template Overview
To gain some perspective, let's begin with a general example that shows how templates work. We'll
explain concepts from the example throughout the section, though you'll probably follow this
without difficulty now:
#include <iostream.h>
#include <rw/cstring.h>
#include <rw/regexp.h>
#include <rw/tvdlist.h>
int main()
{
// Declare a linked-list of strings:
RWTValDlist<RWCString> stringList;
RWTValDlist<RWCString>::iterator iter;
RWCString sentence;
// Add words to the list:
stringList.insert("Templates");
stringList.insert("are");
stringList.insert("fun");
// Now use standard iterators to build a sentence:
iter = stringList.begin();
while (iter != stringList.end()) {
sentence += (*iter++ + " ");
}
// Replace trailing blank with some oomph!
sentence(RWCRegexp(" $")) = "!"
// Display the result:
cout << sentence << endl;
return 0;
}
Output:
Templates are fun!
