Strings HELP (NOT MFC)

Hi People,

I have two strings and need to create one string with the data from string1 and string2 separated by a null terminator. I'm developing eVC++ 3.0

I have listed what I’m trying to achieve below...... :->

String1 = const CHAR newipStr [] = "Kx001";
String2 = char IpNew[34];

String2 = “10.5.99.99”

String3 = String1 + NULL TERMINATOR + String2

String3 = Kx001(NT)10.5.99.99

(NT) = NULL TERMINATOR

Thanks

const char* string1 = "Kx001";
const char* string2 = "10.5.99.99";
char IpNew[34];

int string1size = strlen ( string1) + 1; //including it's NT
int string2size = strlen ( string2) + 1; //including it's NT

memset ( IpNew, 0, sizeof ( IpNew));

memcpy ( IpNew, string1, string1size);

memcpy ( IpNew + string1size, string2, string2size);

If you need to embed null terminators into strings, you may find it easier to use std::string instead of char[]. std::string doesn't treat the '\0' character as anything special (except where the constructor taking a const char* with no length is used).

--------8<--------
#include <iostream>
#include <string>

int main()
{
        const char c_string1[] = "Kx001";
        const char c_string2[] = "10.5.99.99";
        const std::string string1(c_string1,sizeof(c_string1)); // Include the '\0'
        const std::string string2(c_string2); // Don't include the '\0'

        std::string string3 = string1+string2;

        std::cout << "Here it is [" << string3 << "]\nRedirect output to a file to see the '\\0' character!\n";

        const char *data = string3.data();
        std::string::size_type size = string3.size();
        std::cout << std::hex;
        while (size--)
                std::cout << "Character is 0x" << static_cast<int>(*data++) << '\n';
}
