strncpy() fails on second call for same source

Question

I\'m new with c and want to separate string in two parts. Here is my code:

#include 
#include 
#include 

void tes         


        

Answer 1

The array-subscript-operator [] has higher precedence then the dereferencing operator *.

So you want to change

*a[3] = ...

to be

(*a)[3] = ...

Same for b.

Having set the compiler's warning level high enough, it should have warned you about this. Or at least told you that their is something fishy with

*a[3] = '\0';
