(Printing the Decimal Equivalent of a Binary Number) Input an integer (5 digits or fewer) containing only 0s and 1s (i.e., a “binary” integer) and print its decimal equivalent. [Hint: Use the remainder and division operators to pick off the “binary” number’s digits one at a time from right to left. Just as in the decimal number system, in which the rightmost digit has a positional value of 1, and the next digit left has a positional value of 10. then 100, then 1000, and so on, in the binary number system the rightmost digit has a positional value of 1, the next digit left has a positional value of 2, then 4, then 8, and so on. Thus the decimal number 234 can be interpreted as

- (Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?arrow_forwardFind the error(s) in the following code: (6)arrow_forwardWhat will be the output for a and b given the below code segment?arrow_forward
- (Count positive and negative numbers and compute the average of numbers) Write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the maximum, minimum, and average as a floating-point number. Here is a sample run:Enter an integer, the input ends if it is 0: 1 2 -1 3 0The number of positives is 3The number of negatives is 1The maximum is 3.0The minimum is -1.0The average is 1.25arrow_forward) that generates a random even positive integer less than 10 Write a program (Li and displays, using asteriskS, a filled diamond. For example, if the generated length is 4, the program should display a filled diamond like the one below.arrow_forward(a && b) || (c&&d) only gives true when: any of a, b, c, d is true both a,b are true all, a, b, c, d are true a,b is ture or c.d is true O None of abovearrow_forward

It must start with: 4 for Visa cards 5 for Master cards 37 for American Express cards 6 for Discover cards In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine whether a card number is entered correctly or whether a credit card is scanned correctly by a scanner. Credit card numbers are generated following this validity check, commonly known as the Luhn check or the Mod 10 check, which can be described as follows (for illustra- tion, consider the card number 4388576018402626): 1. Double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number. 4388576018402626 → 2 * 2 = 4 → 2 * 2 = 4 → 4 * 2 = 8 → 1 * 2 = 2 6 * 2 = 12 (1+ 2 = 3) → 5 * 2 = 10 (1+ 0 = 1) → 8 * 2 = 16 (1 + 6 = 7) → 4 * 2 = 8arrow_forward4: Format.cpp) Write a program that gets two real values from the user, prints their sum and product in scientific notation, and prints their sum and product in fixed point notation. Print answers to three decimal places.arrow_forward
- Use Python Library Tkinter for This Question! a) Write a function named “ hexToBinary() ” that prompts the user to enter a hex digit and displays its corresponding binary number. Here’s a sample 4-bits binary number: ps(check the photo i atteched to this please because the rest of the question in it. thanks in advance.)arrow_forward(The last term is supposed to be an )arrow_forward(In python please) Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs Yes if every character is a digit 0-9 or No otherwise. Ex: If the input is: 1995 the output is: Yes Ex: If the input is: 42,000 or any string with a non-integer character, the output is: Noarrow_forward
