Q:

Sizeof(const char **) on 32 bit system

What's the value of the expression above? Is there any difference in running it in 32 or 64 bit (I'm on 32 bit) 
Thank you

A:

Value of expression Sizeof(const char **) is 8 on 64 bit machine and 4 and 32 bit machine.
Edit : 
1 byte = 8 bits 
64/8 = 8 bytes and 32/8 = 4 bytes.
