Which of the following properties is true after the assignment (at line 3)?
1 --i, j = 0, 0
2 i, j := i+1, j-1
3 -- ?
i + j > 0
i+j < 0
i+j=0
i = j
5.
Suppose u, v = 10, 5 before the assignment. What are the values of u and v after the sequence of assignments?
1 u :=v
2 v := u
u, v = 5,5
u, v = 5,10
u, v = 10,5
u, v = 10,10
6.
How do we refine a statement?
7.
Why is function an abstraction?
8.
Distinguish between a condition and a statement.
9.
For the given two flowcharts write the pseudo code.
10.
Define a function to double a number in two different ways:
(1) n + n,
(2) 2 x n.
11.

3 if C
4 S2
5 else
6 S3
7 S4
12.
Trace the step-by-step execution of the algorithm for factorial(4).
factorial(n)
--inputs: n is an integer, n > 0
-- outputs: f = n!
f, i := 1 ,1
while i < nf
, i := f × i, i+1
13.
Exchange the contents: Given two glasses marked A and B. Glass A is full of apple drink and glass B is full of grape drink. Write the specification for exchanging the contents of glasses A and B, and write a sequence of assignments to satisfy the specification.

(a)
(1) only
2.
(a)
3.
(b)
S2
4.
(c)
i+j=0
5.

u, v = 5,5
6.
In refinement, each statement is repeatedly expanded into more detailed statements in the subsequent levels.
7.
Once a function is defined, it can be used over and over and over again. Reusability of a single function several times is known as an abstraction.
8.
| statement | condition |
| A statement is a phrase that commands the computer to do an action. | A condition is a phrase that describes a test of the state. |
| In flow chart rectangular box is used | In flow chart diamond box is used |
| Ex. x: = 5 | Ex. If C SI else S2 |
9.
1. Enter A,B
2. Initialise Q-0, r-A
3. If r ≥ B, then do Q-Q+1; r-r-B else r,q
4. Exit.
10.
(1) double (n)
--inputs: n is a real number or an integer, n > 0
--outputs: y is a real number or an integer such that y= n x h.
(2) double (n)
--inputs: n is a real number or an integer, n > 0
--outputs: y is a real number or an integer such that y = 2 x n.
11.
S1; S2; S4
12.
(i) f=1 i=1 f = f * i i = i+1
f = 1 x 1 = 1 i = 2
(ii) f = 1 x 2 i = 3 = 2
(iii) f = 2 × 3 i = 4 = 6
(iv) f = 6 x 4 i = 5 (loop terminates) = 24
