A student took four quizzes in a term and would like to compute their average. He also would like to know what will be the remarks. Follow the range of grades and its equivalent remarks, and then fill-up the table below:100-95 - Excellent94-90 – Very Satisfactory89-85 - Satisfactory84-80 - Fine79-75 - Fair74 and below – Poor   . What statement in the program that determines that the average is passing? 2. What was the condition applied to satisfy the requirement?3. What have you observed in using if-else statement in this program?4. What have you observed in using nested if statement in this program?
A parking garage charges a $2.00 minimum fee to park for up to three hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write a program that calculates and prints the parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for each customer. Your program should print the results in a neat tabular format and should calculate and print the total of yesterday’s receipts. The program should use the function calculateCharges to determine the charge for each customer. Your outputs should appear in the following format Sample output Enter the hours parked for 3 cars: 1.5 4.0 24.0 Car Hours Charge 1 1.5 2.00 2 4.0 2.50 3 24.0 10.00 TOTAL 29.5 14.50
f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…
