How to convert 1D array to 2D array & vice versa, To convert 3D to 4D array & vice versa. Pls send me c progs

I wanted to know how to convert 1D array to 2D array and 2D array back to 1D array in c programming. Again i wanted to Know how to convert 3D array to 4D array and 4D array back to 3D array. please help me, i have an interview on wednesday. All these programs should be worked in c language

How to convert 1D array to 2D array %26amp; vice versa, To convert 3D to 4D array %26amp; vice versa. Pls send me c progs
Memory is linear so you really only have one address after the other in a one dimensional space. 2D arrays show you a different view of this space. A 2D array of [n][m] elements means you have n "chunks" of m elements one after the other in memory. Addressing element [1][0] of an array of [2][3] means you are addressing the first entry (entry 0) of the second "chunk" (of 3 elements) in memory (chunk 1), or address 3*1 + 0 = 3 from the beginning of the array (remember indexes start at 0).





Here is a program to illustrate this. It prints the addresses of memory locations a[i][j] and b[i*m + j] which are the same.





#include %26lt;stdio.h%26gt;





int main()


{


const int n=10;


const int m=15;


int a[n][m];


int *b = %26amp;a[0][0];





int i = 3;


int j = 4;


printf("%p\n%p\n",


%26amp;a[i][j],


%26amp;b[i*m + j]);


}





Going from 3D to 4D follows a similar approach. I'll let you figure it out.
