In the C language, strings are terminated with ASCII NUL (ASCII value 0).
NULs are invisible, so it's possible that the contents of value could be
John\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0Paul\0\0\0...
If this guess is correct, then e.g. strcpy(value[0],string1)
and strcpy(value[1],string2) should copy John and Paul separately.
