no, your not going to reduce memory utilization like I said without writing
your own class, or just using char*.
My test shows that a string is 4 bytes, which is probably just the pointer. I
thought there was more data stored there origenally.
#include <iostream>
#include <string>
using namespace std;
int main(void)
{
string i="hello";
cout << sizeof(i) << endl;
return 0;
}
so your just getting an extra four bytes over what you would get if you were to
use char*.

Subject: Re: Re: [c-prog] memory utilisation by string variables
in a particular c++ program string variables are used to store data loaded
from database,is there any way to use string variable itself,without using
char* or character array,is there any way to reduce memory utilisation by
string variable ,hoping that i made the problem clear to all,please reply
