Declaring Strings

  char a[] = "hello world";
  
  you can that because the compiler knows how much space to allocate for the string "hello world."
  
  char a[];
  a = "hello world";
  
  C won't allow aggregate assignment; you've got an array of chars and a string, which aren't exactly the same thing. you've also got an unknown size - the compiler doesn't know much space to allocate to a.
  
  char a[80];
  strcpy(a, "hello world");
  
  An interesting feature of C though is you can assign structs.
  
  [code]
  typedef struct {
  char a[40];
  } test;
  
  test t1 = { "hello world" }, t2 = t1;
  
  puts(t1.a);
  puts(t2.a);
  [/code]
