Question

modulo examples
modulo has several useful applications. below are just a few.
example 1.5.1: getting digits.
given a number, % and // can be used to get each digit. for a three-digit number user_val like 927:
ones_digit = user_val % 10 # ex: 927 % 10 is 7.
tmp_val = user_val // 10

1.5.1: enter the output of the integer expressions.
type the program’s output
x = 7
y = x % 4
print(y)

Explanation:

Step1: Analyze the operation

The code has \( x = 7 \) and \( y = x \% 4 \). The \% operator is the modulus (remainder) operator. We need to find \( 7 \% 4 \).

Step2: Calculate the modulus

When we divide 7 by 4, the quotient is 1 and the remainder is \( 7 - (4\times1)=3 \). So \( 7 \% 4 = 3 \). Then the print(y) statement will output this remainder.
