GEC Bilaspur Quiz 5 -- C++ -- Prof. Manish Tiwari

Given condition 1: Class A is base class, and there are 5 other classes derived directly from this class (A1, A2, A3, A4 and A5). Each derived class has additional member int z defined in public section of each derived class.

Class A has 2 members declared in private section: <int x1> and <void getdata()>.

Class A has 4 members declared in protected section: <int p1, p2, p3, p4>.

Class A has 2 members declared in public section: <float r1, r2>.

All question further are based on this condition only. Assume every variable and every function takes exactly 1 block of memory.

Q1---In int main() function, if first line of code, how many memory blocks will be allocated after this line is executed.

• 8

• 1

For Condition 1---

Q2---If this is 1 line of code in int main(), how many memory blocks will be allocated in total and how many will have some valid data in these blocks and how many will be empty in these blocks. Answer in 3 parts as "Total Allocated / Valid Data / Empty"

• 8/1/7

• 1/1/0

• 9/0/9

For Condition 1--

Q3--If these are 2 lines of code in int main(), how many memory blocks will have valid data in them.

.....................................................................................

A rt1;

A1 rt2;

A2 rt3;

• 3

• 10

• 0

• 9

For Condition 1--

Q4--If an 8 bit register is considered as "one" block of memory, how many total bits will be allocated in total, if this one line of code is written in int main().

.......................................................................

A1 rt2;

• 1x8

• 9x8

• 7x8

• 8

For Condition 1---Modified--Instead of every variable and function using only 1 block of memory, now variable uses 1 block and function uses 4 blocks of memory.

..................................

Q5--If one block is 8 bit register, how many total memory bits will be allocated after execution of these lines of code in int main().

......................................

Line 1----- int k1;

Line 2---- A1 A9;

Line 3---- A A12;

Line 4---- A4 B1;

Line 5--- B1.z = 45;

• 5x8= 40 bits

• 21x8 = 168 bits

• 28x8 = 224 bits

• 36x8 = 288 bits
