Q$1.$

a$.$ Define operator precedence and operator associativity.

b$.$ What is a ternary operator? What is a prefix operator?

c$.$ What is a coercion?

d$.$ In JavaScript, what is the difference between $==$ and $===?$

e$.$ What is a mixed$-$mode expression?

f$.$ What is short$-$circuit evaluation?

Q$2.$ Let the function fun be defined as

int fun $($int ${?}^{**}k)\{$

$+k+=4$;

return $3+(+k)-1$;

$\}$

Suppose fun is used in a program as follows:

void main $()\{$

int $i=10,j=10,$ sum$1,$ sum$2$;

sum$1=(\frac{i}{2})+$fun$($&$i)$;

${\displaystyle \underset{?}{\overset{?}{}}}2=$fun$({}_j)+(\frac{j}{2})$;

$\}$

What are the values of sum $1$ and sum $2$

operands in the expressions are evaluated left to right?

operands in the expressions are evaluated right to left?

Q$3.$

a$.$ Determine whether the narrowing explicit type conversions in two languages you know provide

error messages when a converted value loses its usefulness.

b$.$ What is a pretest loop statement? What is a posttest loop statement?

c$.$ What is unusual about Python's design of compound statements?

d$.$ What does the range function in Python do$?$

Q$4.$ Rewrite the following pseudocode segment using a loop structure in the

specified languages:

$k=\frac{j+13}{27}$

loop:

if $k>10$ then goto out

$k=k+1$

$i=3+k-1$

goto loop

out: $...$

C$,C++,$ Java, or $C$#

Python

Assume all variables are integer type. Discuss which language, for this code, has the best writability, the

best readability, and the best combination of the two.
