b) given short A[]

c) given char A[]

Solutions

Expert Solution

a) int datatype storage size is 4 bytes and consider the memory starts at 0x0000.

Memory address of A[3]:

3*4=12 bytes=0x000C(hexadecimal address)

Hence the memory address of A[3] is 0x000C.

Memory address of A[10]:

10*4=40 bytes=0x0028(hexadecimal address)(2*16+8)

Hence the memory address of A[10] is 0x0028.

Memory address of A[20]:

20*4=80 bytes=0x0050(hexadecimal address)(5*16+0)

Hence the memory address of A[3] is 0x0050.

b) short datatype storage size is 2 bytes and consider the memory starts at 0x0000.

Memory address of A[3]:

3*2=6 bytes=0x0006(hexadecimal address)

Hence the memory address of A[3] is 0x0006.

Memory address of A[10]:

10*2=20 bytes=0x0014(hexadecimal address)(1*16+4)

Hence the memory address of A[10] is 0x0014.

Memory address of A[20]:

20*2=40 bytes=0x0028(hexadecimal address)(2*16+8)

Hence the memory address of A[3] is 0x0028.

c) char datatype storage size is 1 byte and consider the memory starts at 0x0000.

Memory address of A[3]:

3*1=3 bytes=0x0003(hexadecimal address)

Hence the memory address of A[3] is 0x0003.

Memory address of A[10]:

10*1=10 bytes=0x000A(hexadecimal address)

Hence the memory address of A[10] is 0x000A.

Memory address of A[20]:

20*1=20 bytes=0x0014(hexadecimal address)(1*16+4)

Hence the memory address of A[3] is 0x0014.
