What is the answer of each question:

1-Which of the following operators returns a logical boolean value?

a)=

b)!

c)<

d)!=

e)>!

2-If variables p, q, and r are bool values, which of the following expressions are true?

a) ((p || q) && (p || r)) == (p || (q && r))

b) (p==q && q==r) == (p==r)

c) !!p == p

d) (!p || !q) == !(p && q)

3-Comparing two floating point values for equality using the == operator is considered poor programming practice even if the comparison works as expected.

false

true

4-false && !true || true || 4.2 < -42 && '1'+'2' == 99

false

true

4-Which C/C++ logical binary operator results in the following truth table for the following conditions?

condition 1 condition 2 ralult

false true true

true false true
