Question

Describe a situation in which you would want to use modulus division in a program. Then, write the line of code that would use modulus division.

Answer 1

Modulus division is commonly used to determine whether a number is even or odd - for example, in Python, the following function would return true if the number is even, and false if it is odd:

isEven = lambda x: x % 2 == 0

Or, using traditional function declaration:

def isEven(x):

return x % 2 == 0
