Ex 8) Draw a flowchart for a computer program that will receive numbers andoutput ifthey are divisible by 3 or not until a zero is entered. When a zero is entered, theprogram should output how many of the entered numbers were divisible by 3, thenstop. IMPORTANT RESTRICTION: you are not allowed to divide the number by 3;therefore, you are not allowed to use the remainder operator (%) over 3 to verifythrough the remainder if the number is divisible by 3. You may use any other mathtrick you wish.

The objective of the question is to design a flowchart for a program that accepts numbers as input…

C++ Programming Exercise: 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: a. The total number of of units. b. The rent to occupy all the units. c. The increase in rent that results in a vacant unit. d. Amount to maintain a rented unit. The program then outputs the number of units to be rented to maximize the profit.
(De Morgan’s Laws) In this chapter, we discussed the logical operators &&, ||, and !. DeMorgan’s Laws can sometimes make it more convenient for us to express a logical expression. Theselaws state that the expression !(condition1 && condition2) is logically equivalent to the expression(!condition1 || !condition2). Also, the expression !(condition1 || condition2) is logically equivalentto the expression (!condition1 && !condition2). Use De Morgan’s Laws to write equivalent expressions for each of the following, and then write a program to show that both the original expressionand the new expression in each case are equivalent.a) !(x < 5) && !(y >= 7)b) !(a == b) || !(g != 5)c) !((x <= 8) && (y > 4))d) !((i > 4) || (j <= 6))
Let the function fun be defined as: int fun(int &k) { k += 4; return 3 * k -1; } Suppose the function fun was used in a program as follows: void main() { int i = 10, j = 10, sum1, sum2; sum1 = (i / 2) + fun(i); sum2 = fun(j)) + ( j / 2); } A. What are the values of sum1 and sum2 if the operands in the expressions are evaluated left to right? B. What are the values of sum1 and sum2 if the operands in the expressions are evaluated right to left?

(Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.
(Data processing) Years that are evenly divisible by 400 or are evenly divisible by 4 but not by 100 are leap years. For example, because 1600 is evenly divisible by 400, 1600 was a leap year. Similarly, because 1988 is evenly divisible by 4 but not by 100, it was also a leap year. Using this information, write a C++ program that accepts the year as user input, determines whether the year is a leap year, and displays a message telling the user whether the entered year is or is not a leap year.
(Statistical) In many statistical analysis programs, data values considerably outside the range of the majority of values are simply dropped from consideration. Using this information, write a C++ program that accepts up to 10 floating-point values from a user and determines and displays the average and standard deviation of the input values. All values more than four standard deviations away from the computed average are to be displayed and dropped from any further calculation, and a new average and standard deviation should be computed and displayed.
(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

Use C++ Write a program that simulates flipping a coin to make decisions. The input is how many decisions are needed, and the output is either heads or tails. Assume the input is a value greater than 0. Ex: If the input is: 3 the output is: heads tails heads For reproducibility needed for auto-grading, seed the program with a value of 2. In a real program, you would seed with the current time. In that case, every program's output would be different, which is what is desired but can't be auto-graded. Note: A common student mistake is to call srand() before each call to rand(). But seeding should only be done once, at the start of the program, after which rand() can be called any number of times. Your program must define and call the following function that returns "heads" or "tails".string HeadsOrTails()

Graded Activity #6.1 (M8.1):Part 1: Repetition Control Structure (for)Instruction:Create a flowchart and a java program that reads a positive, non-zero integer as input and checks if the integer is deficient, perfect, or abundant.A positive, non-zero integer, N, is said to be perfect if the sum of its positive proper divisors (i.e., the positive integers, other than N itself, that divide N exactly) is equal to the number itself. If this sum is less than N, the number is said to be deficient. If the sum is greater than N, the number is said to be abundant.The first few perfect numbers are 6, 28, 496, and 8128.
