char text1[] = "hi";
char text2[] = " how are you?";
char final_text[30];

strcpy ( final_text, text1 );
strcat ( final_text, text2 );

or you can do it without text1/2 variables.

also you can:

char string[200];
sprintf ( string, "%s %s", text1, text2 );

Use std::string instead as it's safer, if you need to add more than just strings then use std::stringstream.
