Given the following declarations:
char a[ ] = "abc", *p = "def";

What is the effect of the following statement?

p=a

a. It copies the string "abc" into string p

b. It changes p to point to string "abc"

c. It copies the first character of a ton the first character of p

d. It generates an error

Answer 1

haha cheater.



ya D) is looking good.

Answer 2

Usually it would be b. Because you replaced the adress the pointer points at. But i am not quite sure you can declare a pointer on a string constant (*p="def") - it would probably generate an error.

Answer 3

Genrates Error

Answer 4

p will then point to the first position of a, it won't point to the whole string but you can use pointer arithmatic to get the rest of the string. So - E. none of the above.

Answer 5

The answer is b.



I just wrote a little code to do it, although I should have been smart and just looked at K&R.

Answer 6

b.

p is a pointer to char.

The name of the array a is also a pointer to char.

Answer 7

b. p will point to a which contains "abc".
