b) 5
c) 4

d) double (*p[]) *(float *a);
15) Assume the size of int to be 2 bytes and the program is run on a 486 machine
register int a = 10;
The size of a
a) is 2 as int is assumed to occupy 2 bytes
b) Error ! As it is illegal to find the size of a register variable
c) is 4 as registers of 486 are 32bit in length
d) Compiler dependent
