Expressions Write a console program that prompts the user for 3 double precision floating point values input1, input2, input3. Have the program compute and display the following values. the sum of input1, input2, input3 the average of input1, input2, input3 the log2 of input1 To access the built-in function log2 -- log2(X) computes the base 2 logarithm of X, you need to include the header at the top of your code.

Answer:

b. 2

Explanation:

As we know operator + is supported by the class.Since we know that the + operator binary operator means it needs two operands to work upon it cannot work on one operand.++ operator is unary operator it works on one operand only.

For example:-

a+b

a++.

Hence we conclude that the answer is 2.

Answer:

All of Given

Explanation:

The throw keywords can be used to throw any Throwable object. The syntax is :

throw <Throwable instance>

Note that Error and Exception are subclasses of Throwable while RuntimeException is a subclass of Exception. So the hierarchy is as follows:

Throwable

-- Error

-- Exception

   -- RuntimeException

And all of these are valid throwable entities. As a result "All of Given" is the most appropriate option for this question.

Answer:

The answer is B: throwable

Explanation:

Throwable is the super class of all exceptions

The programreturns uniqueelements in the string passed in with no duplicates. The programis written in python 3 thus :

text = input('Enter text : ')

#promptsuserto enterstring inputs

split_text = text.split()

#splitinputtedtext basedonwhitespace

unique = set(split_text)

#usingtheset function,takeonlyuniqueelementsin thestring

combine = ' '.join(unique)

#usethejoinfunctiontocombinethestringstoformasingle lengthstring.

print(combine)

Answer:

The program to this question as follows:

Program:  

value = input("Input text value: ") #defining variable value and input value by user

word = value.split() #defining variable word that split value

sort_word = sorted(word) #defining variable using sorted function

unique_word = [] #defining list

for word in sort_word: #loop for matching same value

   if word not in unique_word: #checking value

       unique_word.append(word) #arrange value using append function

print(' '.join(unique_word)) #print value

Output:

Input text value: Good morning Good afternoon Good evening

Good afternoon evening morning  

Explanation:

In the above python code, a value variable is defined that uses input function to input value from the user end, and the word variable is declared, which uses the split method, which split all string values and defines the sort_word method that sorted value in ascending order.

• Then an empty list "unique_word" is defined, which uses the for loop and inside the loop, a conditional statement is used.
• In if block, it matches all value is unique if this is condition is true it will arrange all values and uses the print function to print all value.

sample output

Enter f0 = 440

Explanation:

import math                                 // math library  

def RaiseToPower():                 //  RaiseToPower method

 r = math.pow(2,1/12)               //r = 2^(1/12)

f0 = float(input('Enter f0 : '))     //input from user

//a key has a frequency,sy f0

print(f0,end=' ')                      //Display statement

 for n in range(1,5):                //Iterate the loop up to  the next 4 higher key Hz

n = f0 * math.pow(r,n)         //calculate the fn value

print(fn,end=' ')                   //Display statement

 RaiseToPower()                //Call RaiseToPower method
