Please, anyone explain, what is the exact difference between pre increment and post increment?

First, we print a value after we perform post-increment operation (i.e) output become a AB.

a++ is a postfix operation so it should increase the value after the statement, so why BC??

a++ increment its index t0 2.By *a means its content.so prints B.similarly next printf.

The function is not declared before it is invoked, why is the code still running fine?

void fun(char *a) is not declared before main. So why it is not giving an error?

Why we not use fun(*a[0])instead of fun(&a[0])?
@Rishabh. Please tell me.

a[0]='A' Store a[0]=97.
Then a++=98=B.
a++=99=C.
So that Answer is BC.
Then a++=98=B.
