Sir, from when the GO Hardcopy will be available again?

---

Will be updated this week. Probably by May.

a[5]=5[a]=*(a+5)

by same analogy-

a[5][5][5]=(*(*(*(a+5)+5)+5))==*(*(a+5)+5)[5]

*((*(arr+5))[5]+5)==*(arr[5][5]+5)==arr[5][5][5]

so my ans is option (i),(ii),(iii),(iv)

Can you tell me how the storage will be done as we are having array of 3 dimensions and no. is only 123.

suppose int arr[2][3][3]={0};

total number of element in array  =2*3*3

actual all element of array are stored in row major order by default in contiguous manner -

                                     OR

2-

0	0	0
0	0	0
0	0	0

 

0	0	0
0	0	0
0	0	0
