How to concat const char*?

I have three 'const char*' variables i would like to put into one long const char*.
The problem is just that i am simply unable to do so. No sprintf or similar solution worked for me - could someone put my nose into the right direction?

Finally found a solution - why didnt anyone tell me C Libraries could be included? 0o

#include <stdio.h>
#include <string.h>


  char cmd2[80];
  strcpy(cmd2, "<<<");
  strcat(cmd2, cmd);
  strcat(cmd2, ">>>");

Keep in mind that your result isn't actually "one long const char*" though.
