How do I add two strings?

I tried name = \"derp\" + \"herp\";, but I got an error:

Expression must have integral or enum type

Answer 1

using memcpy

char *str1="hello";
char *str2=" world";
char *str3;

str3=(char *) malloc (11 *sizeof(char));
memcpy(str3,str1,5);
memcpy(str3+strlen(str1),str2,6);

printf("%s + %s = %s",str1,str2,str3);
free(str3);
