Assign Memory to 3D array using triple pointer

Question

I have to assign memory to a 3D array using a triple pointer.

#include 
int main()
{
    int m=10,n=20,p=30;
    char ***z;
    z = (char***)          


        

Answer 1

You want sizeof(char) not sizeof(char**) as the latter will give you the size of a pointer which on most modern systems will be 4 bytes instead of the 1 you're expecting.
