can anyone pls explain the solution for 5th question. when the run the I get the output as 43. but i would like to the logic behind it
++arr[++x] is parsed x=1(pre-increment)
thrfore ++arr[++x] is equivalent to ++arr[1] which gives 20+1=21
21+ ++x + arr[--x]
21+2+ arr[--x] since x is pre-incremented
23+arr[--x]
23+arr[1] since x is predecremented
23+20
=43
21+ ++x+arr[--x]
21+2+arr[--x]
23+arr[--x]
23+21 since arr[1] is already pre-incremented the value of arr[1] is 21
=44
answer should be equal to 43
i cant find the download original link. please post the link
