Answer:
Explanation:
The following code is a Python function that takes in the amount of change. Then it uses division and the modulo operator to calculate the number of coins that make up the changes, using the greatest coin values first.
import math
def amountOfCoins(change):
print("Change: " + str(change))
quarters = math.floor(change / 0.25)
change = change % 0.25
dimes = math.floor(change / 0.20)
change = change % 0.20
pennies = math.floor(change / 0.01)
print("Quarters: " + str(quarters) + "\nDimes: " + str(dimes) + "\nPennies: " + str(pennies))
Depending on which computer you have you can go into settings and check the data tab or it should be on the box how much it comes with :)
3. 8.1
Looking at the functions "average", and "mystery" it's pretty obvious that "average" returns a double precision average of the value of an integer array. The function "mystery" returns an array of integers with each value in the array being the length of the string in the array of strings passed to "mystery" in the same ordinal position.
The main body of the code initializes an array of strings and then passes that array to "mystery" who's output is then passed into the function "average". Since the lengths of the words passed to "mystery" is 7, 5, 6, 10, 10, 8, 13, 6, 8, 8, the sum will be 81, so the average will be 81/10 = 8.1 which matches option "3".
Answer: str[0].toUpperCase();
Explanation:
str[0] is pointing to the first character of the entire string and the code str[0].toUpperCase() will convert the characters to upper case if they are in lowercase and will remain unchanged if they are already in upper case.
Answer:
Option(c) is the correct for the above question.
Explanation:
The full form of SDLC is System Development Life Cycle, Which tells the rules and processor which have to follow by any software developer. It gives the benefits to make the error-free software.
Another option is invalid because--
- Option a tells that the SDLC is a method but it is a formal processor.
- Option b tells that the SDLC is a framework but it is not any framework it is a guideline.
- Option d tells that the collection of theorems that are used to change in software projects but it is only the model, not any theorems.
