Simple string question...

char* stringtofile; 

/* c style */
stringtofile = malloc(mylength* sizeof(char));
// c++ style
stringtofile = new char[mylength];
 

/* c style */
free stringtofile;
// c++ style
delete[] stringtofile;
 

  #include <iostream>
#include <string>  // string class header; no .h extension


using namespace std;
int main(int argc, char *argv[])
{
  string str = "This is a string.";
  cout << str;
  str += " I appended a second string to it dynamically.";
  cout << ''\n'' << str;
  str += "\nAnd I appended a new line."
  cout << str << endl;
}  

This is a string.
This is a string. I appended a second string to it dynamically.
This is a string. I appended a second string to it dynamically.
And I appended a new line.

I''m pretty sure class string'' methods are optimized for dealing with the entire string as one object, while vectors are optimized for managing each container individually.

basic_string<charT, traits, Alloc>:
The types string and wstring are typedefs for, respectively, basic_string<char> and basic_string<wchar_t>.
