```
C. ```

```
D. ```
char stringVar[6] = “Hello”;
```
E. ```
char stringVar[] = “Hello”;

Answer 1

a) c) d) e)
Note that a) and c) have the same size C-string variable and have the
same size C-string. d) and e) have the same size C-string variable and have the same
size C-string, but the size of the C-string variable is different from a) and c). The
character array in b) is not terminated, so the array does not contain a C-string at all.
