what does the following do?
int array[6] = { 5, 3, 4, 17, 22, 19 };
int* ptr = array[0]
*ptr = -1;
thank you!

The first line initializes the values of the array.
The second line is a syntax error. It should be int* ptr = &array[0]; The last line sets the value of te first array element to -1.

Think about it and post your answer (or guess)

okies..
so this is what i thought:
ptr+= 2
increases the pointer by two.. so the ptr will now point to array[2]
and ptr[1] =9
the value of index 1 is equal to 9..
is this correct?
thank you!

yes, but in the original array which element is set to 9?
dsuh06 0 Newbie Poster
