Question

How these two statements are equivalent
1.*(s+2)
2.*(*(s+2)+1)
where s is a two dimensional array.S[3][2].

Answer 1

A two dimensional array is internally stored as 1-D. So you can refer to start of first row by s+1, second row by s+2. And each row will start from first element . So *(s+1) print s[1][1] , *(s+2) prints s[2][1] and also *(*(s+2)+1) will refer to s[2][1].

Answer 2

As i think,these two statement are not equal,because
above statement
*(s+2)=s[2][0] (in case of 2D array)
while
below statement
*(*(s+2)+1)=s[2][1]

Remember,the index counting start from zero.

Answer 3

When I programmed the above codes both are reffered to same location.But I can't resolve them.

Answer 4

yes Md. Azam is right *(s+2) will refer to s[2][0] and *(*(s+2)+1) to s[2][1] as index starts from 0 in C.
