An output for the C++ (version 14) program executed above
is:
1. sizeof(s1) = 5
2. s1 == s2 is false
3. s3 == s4 is true
4. The values stored in v are 8 8 8 8
5. s4 = joes
6. s5 = zoey
7. What is the value of (q[1] + q[2])?
8. What is the value of q?
9. p2 = 140726181901504, q = 140726181901504
10. p2 = 0x7ffd5e1534c0, q = 0x7ffd5e1534c0
Answer the following 10 questions based on the C++ program and
its
output above.
1. In the output for 1 above, why is sizeof(s1) = 5 even though
s1 contains only four letters? What is character is being
stored in the fifth byte of s1?
2. In the output for 2 above, why does s1 == s2 result in false
when both s1 and s2 contain the same character sequence?
What values are being compared in s1 == s2 to yield a result of
false?
3. In the output for 3 above, why does s3 == s4 result in true?
What values are being compared in s3 == s4? What
types of strings are s3 and s4, and how are they different than
the types of string used for s1 and s2?
4. In the output for 4 above, explain why the values stored in v
are all 8? Explain your answers in terms of how the
memory addresses are being stored for d. Assume the starting
address of d is 500, then what are the memory addresses
for d[0], d[1], d[2], d[3], and d[4]?
5. Why is joes in the output for 5 above? Explain how the first
character in s4 was changed to ’j’. Explain how the last
character in s4 was changed to ’s’.
6. Why did the output for 6 above print s5 = zoey instead of s5
= zoey is awesome?
7. As asked in the output for 7 above, what is the value of
(q[1] + q[2])? Is it correct syntax to use *(q[1] + q[2]) to
compute the value of (q[1] + q[1])? Explain why this syntax is
correct or why it isn’t correct.
8. As asked in the output for 8 above, what is the value of q?
Explain what this value represents in terms of what is going
on in the program’s memory at runtime.
9. Consider the output for 9 and 10 above. Why do these memory
addresses typically change each time this program is
run on odin?
10. Consider the output for 9 and 10 above. The memory addresses
that are being display to standard output for 9 above
are using which number system: binary, octal, base-10, or
hexadecimal? The memory addresses that are being display
to standard output for 10 above are using which number system:
binary, octal, base-10, or hexadecimal?
