Submit your answer in the comment section. Days of the Week Write a program that asks the user for a number in the range of 1 through 7. The program should display the corresponding day of the week, where 1- Monday. 2- Tuesday and so forth. If the user types in a 6 then "Saturday should be printed on the screen. For help with Input statements see: Input Function • The program should print an error message if the user enters a number that is outside the range of 1 through 7. For help with If statements and conditions see the following pages: If-Eke Statements and Operators • Name the source code file yourName HW4_1.py. • Test and run the program.

1- If money is left in a particular bank for more than 5 years, the bank pays interest at a rate of 4.5% of the money; otherwise, the interest rate is 3.0% of the money. Write a program to accept the number of years in the variable numYears and money in the variable money then display the correct interest rate, depending on the value input into numYears 2- Write a program that accepts a user-entered number and calculates the square. Before calculating, check that the number is negative, and isn't zero. If either condition occurs, display a message stating that the operation can't be calculated. 3- Write a program which accept a number of 2 digits and check if ones digit is greater than the tens digit print the number in reverse order, if each of the ones digit and the tens digit greater than 5 print the average of them (ones and tens), otherwise print the message( NOT valid ). 4- Write C++ program to accept a number num (with any number of digits).

(Misc. application) a. Write a program to reverse the digits of a positive integer number. For example, if the number 8735 is entered, the number displayed should be 5378. (Hint: Use a do statement and continuously strip off and display the number’s units digit. If the variable numinitially contains the number entered, the units digit is obtained as (num % 10). After a units digit is displayed, dividing the number by 10 sets up the number for the next iteration. Therefore, (873510)is5and(8735/10)is873. The do statement should continue as long as the remaining number is not 0.) b. Run the program written in Exercise 3a and verify the program by using appropriate test data.
25. Repeat Programming Exercise 24, but the wire is to be bent in the form of a circle. In this case, the user specifies the length of the wire and the program outputs the radius and area of the circle. (You may assume that . Also declare it as a named constant.)
4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }
(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.
