Question

I would like to know how to add a string to array of char*

#define FROM    "<[e-mail]>"
#define TO      "<[e-mail]>"
#define CC      "<[e-mail]>"
#define SUBJECT "TESTING SUBJECT"

string testing("USING variables");
const char * c = "Subject: ";

static const char *payload_text[]={
"To: " TO "\n","From: " FROM "\n","Cc: " CC "\n",c "\n",
"\n", /* empty line to divide headers from body, see RFC5322 */
SUBJECT "\n",
"\n",
"Testing the msg.\n",
"Check RFC5322.\n",
NULL
   };

I would like to add either c or the variable testing to the array of payload_test[]
or is there other way to create the array paylod_text[] with user insiated variables.

Answer 1

If you want to add testing then just put it in the parameters as

testing.c_str()

Also one more way is there

string body="Testing the msg.\n";
body+=testing;
body+="Bye ....";

And to put in array use

body.c_str();
