Relational Operators practice: (Interactive mode)

Q. Relational Operators' practice: (Interactive mode)

x = 29.0, y = 13, z = 2, p = 0.5, q = 12.79, i = 13, j = 29.0, k = y – 11, a = ''(empty string), b = '', c = 'great', d = 'Great', e = 'GREAT', f = 'Great', g = 'GREAT', h = ' great'

Answer :-

 
	 
S. No.
 
	 
Expression
 
	 
Result
 
	 
Reason
 
 
 
	 
1
 
	 
y > p * 26
 
	 
False
 
	 
We should know the precedence order of operators.
 
 
 
	 
2
 
	 
(y > p) * 26
 
	 
26
 
	 
(1{means True}) * 26
1 * 26
26
 
 
 
	 
3
 
	 
x <= y < x + y
 
	 
False
 
	 
We should know the precedence order of operators.
 
 
 
	 
4
 
	 
x // y < p * 20
 
	 
True
 
	 
Precedence order of ‘*’ and ‘//’ greater then ‘<’ operator.
 
 
 
	 
5
 
	 
x != y * z + 3
 
	 
False
 
	 
Precedence order of ‘*’ and ‘+’ greater then ‘!=’ operator.
 
 
 
	 
6
 
	 
x == y * z+3
 
	 
True
 
	 
Precedence order of ‘*’ and ‘+’ greater then ‘==’ operator.
 
 
 
	 
7
 
	 
x - 3 != y * 2
 
	 
False
 
	 
Precedence order of ‘*’ and ‘-’ greater then ‘!=’ operator.
 
 
 
	 
8
 
	 
x - (3 != y) * 2
 
	 
27.0
 
	 
Precedence order of ‘()’, ‘*’ and ‘-’ greater then ‘!=’ operator.
 
 
 
	 
9
 
	 
a == b
 
	 
True
 
	 
Both are empty string, So their id is same.
 
 
 
	 
10
 
	 
c == d
 
	 
False
 
	 
Both variables have different values look carefully.
 
 
 
	 
11
 
	 
d == g
 
	 
False
 
	 
Both variables have different values look carefully.
 
 
 
	 
12
 
	 
f == d
 
	 
True
 
	 
Both variables have same value so their id is same.
 
 
 
	 
13
 
	 
e == g
 
	 
True
 
	 
Both variables have same value so their id is same.
 
 
 
	 
14
 
	 
h == c
 
	 
False
 
	 
Both variables have different values look carefully.
