C++ Question (if and while loops)

1 answer:

8 0

Your while statement is in error

<span>while (wage = 0) assigns 0 to wage.

What you want is to compare wage to 0, ie.:

while (wage == 0).

However, comparing double's to some value is very bad practice due to rounding errors. Much safer is to always have a < or > in there:

while (wage < 0.0001)

If you confuse assignment (=) and comparison (==) often, and you don't have a compiler to warn you for this, you can adopt the coding style to put the constant first:

while(0 == x)</span>

Complete the divisible_by(list1, int1) function below. As input, it takes a list of integers list1 and an integer int1. It shoul

damaskus [11]

Answer:

The function is as follows:

def divisible_by(listi, n):

mylist = []

for i in listi:

if i%n == 0:

mylist.append(i)

return mylist

pass

Explanation:

This defines the function

def divisible_by(listi, n):

This creates an empty list

mylist = []

This iterates through the list

for i in listi:

This checks if the elements of the list is divisible by n

if i%n == 0:

If yes, the number is appended to the list

mylist.append(i)

This returns the list

return mylist

pass

Suppose that you have created a program with only the following variables.int age = 34;int weight = 180;double height = 5.9;Supp

Yuri [45]

Answer:

a. calculate(age, weight); // This is legal

b. calculate(age, height); // This is legal

c. calculate(weight, height); // This is legal

d. calculate(height, age); // This is not legal

e. calculate(45.5, 120); // This is not legal

f. calculate(12, 120.2); // This is legal

g. calculate(age, size); // This is not legal

h. calculate(2, 3); // This is legal

i. calculate(age); // This is not legal

j. calculate(weight, weight); // This is legal

Explanation:

a. This is legal because the argument passed are two in numbers and they are integers but the integer for the second parameter can be cast to double.

b. This is legal because the method requires two parameter and two are passed. The method requires integer and double. The passed parameter are integer and double.

c. This is legal because the method requires two parameter and two are passed. The method requires integer and double. The passed parameter are integer and double.

d. This is not legal because even though two parameters were passed. The first one should be int but double was supplied and double cannot be downgraded to int. There is a possible lossy conversion from double to int.

e. This is not legal because even though two parameters were passed. The first one should be int but double was supplied and double cannot be downgraded to int. There is a possible lossy conversion from double to int.

f. This is legal because the method requires two parameter and two are passed. The method requires integer and double. The passed parameter are integer and double.

g. This is not legal because even though two parameters were passed. The first one should be int but the second parameter is not defined before been passed to the calculate method.

h. This is legal because the argument passed are two in numbers and they are integers but the integer for the second parameter can be cast to double.

i. This is not legal because only one parameter was passed instead of two.

j. This is legal because the argument passed are two in numbers and they are integers but the integer for the second parameter can be cast to double.
