- (IN C LANGUAGE) Binary-Decimal / Decimal Binary . Between 0 and 255 a number will be decided randomly by computer. Then asks to user 3 times a random digit of binary value of the that number. If user enters wrong number for a digit program will select another random number and ask random times random digit. For example: Computer selected number as 163 ( Which is 10100011) What is the digit 2 (question 1/3) :User enter 1 CorrectWhat is the digit 4 (question 2/3) : User enter 0 CorrectWhat is the digit 7 (question 3/3) : User enter 0 CorrectUser finished the quest with 3 input .arrow_forward(python) Study the following code, specifically the loop. _sum = 10 for k in range (2, 20, 3): _sum = _sum + (2*k) if _sum > 100: print("exceeded 100") Now, rewrite the for loop (for k in range(2, 20, 3):)to be a while loop that accomplishes the same objective. You don't need to show/use the other lines.arrow_forward(Display patterns using loops) Use nested loops that display the following patterns in two separateprograms: pattern A Pattern B Pattern c 123456 1 3 1 6 1 2 3 3 3 1 6 1 2 3 4 5 3 3 3 1 6 1 2 3 4 5 6 7 3 3 1 6 1 2 3 4 5 6 7 8 9 3 123456arrow_forward
- (PYTHON) A Krishnamurthy number is a number which sum of the factorial of its digits is equal to the number itself. For example: Let us consider the number 145. Factorial sum = 1! + 4! + 5! = 1 + 24 + 120 = 145. Therefore 145 is a Krishnamurthy number. Other examples include: 1, 2, 40585. Write a program that does the following: • asks the user to input an integer. • computes whether the number is a Krishnamurthy number. • then finally prints the result. Note: You are not allowed to use the built-in function math.factorial.arrow_forward(Electrical eng.) a. The voltage gain of an amplifier is given by this formula: voltagegain=[275 23 2 +0.5 f 2 ]n f is the frequency in Hz. n is the number of stages in the amplifier. Using this formula, write, compile, and run a C++ program to determine the value of the voltage gain for a four-stage amplifier operating at a frequency of 120 Hz. Your program should produce the following display: At a frequency of xxxxx hertz, the voltage gain is yyyyy Your program should replace xxxxx with the frequency and yyyyy with the voltage gain. b. Manually check the value your program produces. After verifying that your program is working correctly, modify it to determine the voltage gain of a 12-stage amplifier operating at a frequency of 9500 Hz.arrow_forwardLanguage: C++ (Apartment problem) A real estate office handles , say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program that prompts the user to enter: The total number of units. The rent to occupy all the units. The increase in rent that results in a vacant unit. Amount to maintain rented unit. The program then outputs the number of units to be rented to maximize the profit. Note: Please include the pseudocodearrow_forward

You are expected to take in a single positive integer which will be used as the number of steps in your staircase. The program only accepts integers greater than 0 and less than 500. If 0 is entered a message stating "Your staircase has no steps." and if the user enters a value greater than or equal to 500, a message stating "I can't build a staircase that tall." For all other values not within the valid range or not integers an "Invalid staircase size provided." will be displayed to the user. The program will always run only once for each user input. One thing to note, the messages should be the return string from your createSteps() function and printed from the calling function. Additional Requirements: 1. The very first step in the stair case will be left aligned and for each subsequent level the step will move above and to the right of the prior step. 2. There are no spaces after the right of any of the steps. 3. The bottom most…arrow_forward(Python) Please write a program that creates steps.

- (In java) Lab6C: Cha-Ching For this lab, use a do-while loop.A sentinel loop is a loop (a special while loop or a do-while loop) that continues to process data until itreaches a specific value(s) that signals that it should stop looping; this special value(s) is usuallyindicated as the condition of the while or do-while loop. A good example of a sentinel loop is the whileloop that you had to write to verify user input in Lab6B, the special values were anything in the range of1 to 1000. Another very common application for this is allowing a user to rerun a program.Please write a very simple program that mimics a bank account. The program should start the user outwith $1000. The program should print out a welcome menu once with the options present for the user.The program should allow the user to make a deposit, withdrawal, and see their current balance.Every time the user deposits or withdraws, the program should show the user their new balance; itshould also ask the user if they want…arrow_forward(C PROGRAMMING ONLY) 6. Deal or No Deal?by CodeChum Admin When I was a kid, I used to watch this TV game show, Deal or No Deal? In the game, there are different brief cases, each labeled with a number. Inside each brief case is an amount in Pesos and the goal is to guess which briefcase contains the smallest amount. In this program, instead of just finding the smallest amount, your task is to ask the user for an integer input and print the values in the array smaller than the inputted integer. Instructions: In the code editor, you are provided with an array with 100 elements.Your task is to ask the user for an integer input and then print all the elements in the array whose value is lesser than the inputted integer.Input 1.
