I can see why
Char *encDate = "34857384573498573498";
might fail. Because you're assigning a pointer to some temp variable. It
depends on when that temp variable decides to go out of scope, that pointer
may no longer be valid. (Although I could be wrong. I'm not a C expert.)
However, I'm not sure why
Char encDate[] = "34857384573498573498";
fails. Because this time you're actually creating a variable on the stack
and initialize the content with the indicated string.
I'm sorry I couldn't help you further.
