Would this be safe?

I am new to the C++ world, after spending many years as a C programmer.
I am attempting to convert a std::string to a array of characters (C
string), to enable me to send the data via a socket.
I realise that discussion of none standard functions is off topic here,
so for the purpose of this discussion, lets pretend that is not what I
am trying to achieve.

Coming from a C background, I have had it drilled into me to always try
to avoid buffer overflows especially when dealing with arrays of
characters. So with this in mind I ask the following question:

Is the code below safe?

#include <iostream>
#include <cstdio>
#include <string>

int main (void)
        std::string hello, hello2;
        hello = "This is a C++ String";

        std::cout << hello << std::endl;
        const char *cstring = hello.c_str();
        for(int i = 0; i < strlen(cstring); i++){
                if( i == 7)
                        printf(" \nn\no\nt\n");
                printf("%c\n", cstring[i]);

        hello2 = cstring;
        std::cout << hello2 << std::endl;
        return 0;

Thanks in advance.
