4.18 LAB: Input and formatted output: House real estate summary Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current.price 0.051)/12. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f)'.format (your_value)) Ex: If the input is: 200000 210000 the output is: This house is $200000. The change is $-10000 since last month. The estimated monthly mortgage is $850.00.

7. We usually write numbers in decimal form (or base 10), meaning numbers are composed using 10 different "digits" {0,1,.9). Sometimes though it is useful to write numbers in hexadecimal or base 16. Now there are 16 distinct digits that can be used to form numbers: {0,1,..,9,A,B,C,D,E,F}. So, for example, a 3 digit hexadecimal number might be 3B8. (a) How many 2-digit hexadecimals are there in which the first digit is E or F? Explain your answer in terms of the additive principle (using either events or sets). (b) Explain why your answer to the previous part is correct in terms of the multiplicative principle (using either events or sets). Why do both the additive and multiplicative principles give you the same answer? (c) How many 3-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)? Explain. (d) How many 3-digit hexadecimals start with a letter (A-F) or end with a numeral (0-9) (or both)? Explain.
09.Text:Python Programming You are given an exhibit an of length N and Q inquiries. Each question is portrayed by a couple of whole numbers, I and r. Answer each inquiry with the accompanying: assuming we take each aftereffect of the components with lists among 1 and r (comprehensive) and record their items, what will be the littlest missing positive number? Input • The primary line of the information contains a solitary number T signifying the quantity of experiments. The portrayal of T experiments follows. The primary line of each experiment contains two space-isolated numbers N and Q. The subsequent line contains N space-isolated numbers a1, a2,..., an. Every one of the following Q lines contains two space-isolated numbers, I and r, meaning the question's reach. . Yield For each question, yield the littlest missing aftereffect item on a new.
09. Python Write the in_order() function, which has a list of integers as a parameter, and returns True if the integers are sorted (in order from low to high) or False otherwise. The program outputs "In order" if the list is sorted, or "Not in order" if the list is not sorted. Ex: If the list passed to the in_order() function is [5, 6, 7, 8, 3], then the function returns False and the program outputs: Not in order Ex: If the list passed to the in_order() function is [5, 6, 7, 8, 10], then the function returns True and the program outputs: In order Note: Use a for loop. DO NOT use sorted() or sort()..
Add a function to get the CPI values from the user and validate that they are greater than 0. 1. Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4. Replace the code that was moved with a call to this new function. - Add an array to accumulate the computed inflation rates 1. Declare a constant called MAX_RATES and set it to 20. 2. Declare an array of double values having size MAX_RATES that will be used to accumulate the computed inflation rates. 3. Add code to main that inserts the computed inflation rate into the next position in the array. 4. Be careful to make sure the program does not overflow the array. - Add a…
Can you write a new code in C language with the values I sent you, just like this output? There are two files named group1.txt and group2.txt that contain course information and grades of each student for each class. I will calculate each course average for each group and show in simple bar graph. Use "*" and "#"characters for group1 and group2, respectively. I will see the number -999 at the end of each line in the input files. This value is used for line termination and you can use it to verify that you have arrived at the end of the line. The averages of each group should also be calculated and printed at the end of the file.

***PLEASE LOOK AT IMAGES AS WELL FOR HELP*** Write a program that reads five cards from the user, then analyzes the cards and prints out the category of poker hand that they represent. Poker hands are categorized according to the following labels: Straight flush, four of a kind, full house, straight, flush, three of a kind, two pairs, pair, high card. To simplify the program we will ignore card suits, aces, and face cards. The values that the user inputs will be integer values from 2 to 9. When your program runs it should start by collecting five integer values from the user. It might look like this (user input is in bold red for clarity): Enter five numeric cards, no face cards. Use 2 - 9.Card 1: 8 Card 2: 7Card 3: 8Card 4: 2Card 5: 3 (This is a pair, since there are two eights) Since we are ignoring card suits there won’t be any flushes. Your program should be able to recognize the following hand categories, listed from least valuable to most valuable: Hand Type…
3.1- The Randomness Score As stated above, the main task of this program is to compute a randomness score based on how different the inputted string is after being shuffled. To do this, you will implement the following: • Your calculation will start with the first character of the initial string and the shuffled string. • You will take the difference between the ordinal value of each character and add that value to your final score. • You will then move to the next character and repeat the process until you have gone through each entire string. For example, say we input the string "Kevin" and it shuffles into "vKnei". We would then do the following calculation: K 75 118 43 K 101 75 26 In 118 110 8 105 101 4. 110 105 Note that when we take the difference between ordinal values, we convert it to its absolute value to make sure it always stays positive. This means that the total randomness score is 43+26+8+4+5-86. 2
3.6 LAB: Number pattern Write a recursive function called print_num_pattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For coding simplicity, output a space after every integer, including the last. Do not end output with a newline. Ex. If the input is: 12 3 the output is: 12 9 6 3 0 3 6 9 12
2.16 LAB: Musical note frequencies On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of fO * r^, where n is the distance (number of keys) from that key, and r is 20/12) Given an initial key frequency, output that frequency and the next 4 higher key frequencies.
