Write a program that requests the current time and a waiting time as two integers for the number of hours and the number of minutes to wait. The program then outputs what the time will be after the waiting period. Use 24-hour notation for the times. Include a loop that lets the user repeat this calculation for additional input values until the user says she or he wants to end the program. Input Notes:Both the current time and the waiting time are entered in the form HH:MM where HH and MM are integers signifying hours and minutes respectively. In response to the continuation prompts (described below) the user types a y or a Y to signify "continue" with any other character signifying "quit". Output Notes (Prompts and Labels):At the outset the program prints the title "Compute completion time from current time and waiting period". The program then prompts for the current time with the prompt "Current time:" followed by the instructions "Enter 24 hour time in the format HH:MM". After…

Write a program that uses loops to collect data and calculate the average score over a number of tests for a number of students. Use Small Basic for this assignment. The program should : 1. first ask the user to enter the number of students in the range of 1 to 10. 2. then the program asks the user to enter the number of tests (in the range of 1 to 5) 3. Then use a loop to collect the scores for those many tests for each student. The outer loop will iterate once for each student. The inner loop will iterate several times, once for each test. Each iteration of the inner loop will ask the user to enter the score for a test of a student. 3. After all iterations, the program should calculates and display the total scores and average score for each student.

You want to determine the amount you will save for a down payment on a home in the next 3-7 years. You are opening an account with $750. Each year a contribution of $2400 will be made. Assume that there is a 2.75% compound interest rate paid on the balance at the end of the year. Display the year and the savings amount at the end of each year - beginning with the current year. Write your program using a loop that displays the projected savings for each year. (Try using a function that calculates the end of year interest - pass the balance (previous balance plus investment ($2400)), calculate the interest and return the interest amount))
