Question

Three students have written functions for squaring a number. They have used their function in a program to square the number 4. Which of the following three programs includes a function for squaring any number and is called correctly in the program?

Select one:

a.

def squared(integer):
    return number * number


number = 4
result = squared(number)

b.

def squared():
    return number * number

number = 4
result = squared()

c.

def squared(integer):
    return integer * integer

number = 4
result = squared(number)

Answer 1

Ans is C

def squared(integer):
    return integer * integer

number = 4
result = squared(number)

in b the function does not have any argument and so it will gives the error because variable number is not define in the function.

in a the function receive the argument in variable called integer and in function they are using the variable named number that is not define in the function.so it also will gives the error,

so both a and b are incorrect. and c is the correct ans for you.
