- 5: CheckLetter.cpp) Write a program that adds a check letter to an eight-digit number. The check letter should be computed as follows: Break the number up into 4 two-digit numbers. Add the four numbers together. Find the remainder after division by 26. The check letter is the letter in the alphabet that corresponds to the number just computed. (A=0, B=1, C=2, etc.) Print the original number followed by the check letter. Use at least one function that returns a value when you write this program.arrow_forwardComplete the following Codearrow_forward1. Federal law requires that hourly employees be paid “time-and-a-half” for work in excess of 40 hours in a week.For example, if a person’s hourly wage is $12 and he or she works 60 hours in a week, the person’s gross pay shouldbe (40 *12) + (1.5 *12 * (60-40)) = $840.Write a program that requests the floating number of hours a person works in a given week and the person’s hourlywage as input, and then displays the person’s gross pay. Save it as overtimePay.pyarrow_forward

Write a program to perform the following checks on the substation:i) display all voltages that differ from the average by more than 10% of the average.ii) display all pairs of consecutive hours where the change from the voltage at one hourto the next is greater than 15% of the average.arrow_forwardComplete the function that calculates the sum of the first n+1 terms of the geometric series a, ar, ar² ar³, art Note that the series begins with a and the last term is ar", in total there are n+1 terms. # complete the function given the variables a,r,n and return the value as series_sum. def sum geometric_series (a,r,n): # YOUR CODE HERE return series_sum ... arr print (sum_geometric_series (4.0, 5, 10))arrow_forward
- Q2) Write a program that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word "Yes". If the sentence ends with a question mark and the input contains an odd number of characters, display the word "No". If the sentence ends with an exclamation point (!), display the word "Wow". In all other cases, display the words " you always say "followed by the input string enclosed in quotes" ". Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a legitimate sentence. Sample Input#1: Please enter a one line question or statement. How are you? Sample Output#1: Yes Sample Input #2: Please enter a one line…arrow_forwardstoppingDistance = speed * (2.25 + speed / 21)Write a program which determines whether a vehicle’s tailgating distance is safe.The program should read in the speed of the vehicle and the vehicle’s tailgatingdistance. The program should then calculate the distance that would be required tostop the vehicle.arrow_forwardExams.cpp) Suppose a teacher weights the fourexams he gives 10%, 25%, 30%, and 35%. Write a programthat reads ten sets of four grades, prints the weightedaverage of each set, and prints the unweighted average ofeach test. The number of students should be in a globalconstant.arrow_forward
- Chess bishop moves diagonally in any number of squares. Given two different squares of the chessboard, determine whether a bishop can go from the first square to the second one in a single move. The program receives four numbers from 1 to 8 each specifying the column and the row number, first two - for the first square, and the last two - for the second square. The program should output YES if a bishop can go from the first square to the second one in a single move or NO otherwise. Define a function called bishop_move # Example input ```4455``` # Example output ```YES``` #arrow_forwardVPython 3500) assignments/3090165 Answers to ms to Canvas for the following problems. There should be 7 programs. 4B, 5, 6 1. A. Write a VPython program that creates eight spheres, each placed at one corner of a cube centered on the origin. The length of a side of the cube should be 6 units, and the radius of each sphere should be 0.5. Use at least two different colors for the spheres. B. Add to the program an arrow whose tail is at one corner of the cube and whose tip is at the corner diagonally opposite. The figure below shows the display from one possible solution to this problem. 2. Write a VPython program that represents the x, y, and z axes by three cylinders of different colors. This display from one possible solution is below.arrow_forwardQuestion 3 The results from the mayor's race have been reported by each precinct as follows: Table 2: Results of mayor's race Precinct Candidate A Candidate B Candidate C Candidate D 1 192 48 206 37 147 90 312 21 186 12 121 38 4 114 21 408 39 267 13 382 29 Write a program to do the following: (a) Display the table with appropriate labels for the rows and columns.
