Assignment 2 BCS 1223 AD

1. A University has 3000 students. These students are divided in four catogeries:

i) B. Tech
ii) M. Tech
iii) M.S
iV) Ph.D

Write an algorithm or for finding the percentage of the students in each category.

 2. Write an algorithm  for a program that prompts the user to enter the number of students and each student's name and score, and finally displays the student with the highest score


 3. Write an algorithm  for a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values, not counting zeros. Your program ends with the input 0. Display the average as a floating-point number. (For example, if you entered 1, 2, and 0, the average should be 1.5.)

I. Write a program for finding the sum of first 100 even numbers starting from 0.

II. Read 10 integers and find the total of even number and odd number entered.

III. Read 10 integers and find the total of positive number and negative number.

IV. Write a program that prompts the user to enter the number of students and each student's name and score, and finally displays the student with the highest score.

2. Write method headers for the following methods:

1. Computing a sales commission, given the sales amount and the commission rate.
2. Printing the calendar for a month, given the month and year.
3. Computing a square root.
4. Testing whether a number is even, and returning true if it is.
5. Printing a message a specified number of times.
6. Computing the monthly payment, given the loan amount, number of years, and annual interest rate.
7. Finding the corresponding uppercase letter, given a lowercase letter.

3.	(Converting an uppercase letter to lowercase) Write a method that converts an uppercase letter to a lowercase letter. Use the following method header: public static char upperCaseToLowerCase(char ch)
4.	(Computing commissions) Write a method that computes the commission, using the following rate table . The header of the method is: public static double computeCommission(double salesAmount)

Sales Amount                      Commission Rate

$0.01–$5,000                        8 percent

QUIZ 2 (CHAPTER 4 LOOPS)

Name:_______________

Matric:______________

Please submit before 5:00 pm 4/11/12.

SECTION A

• 1. There are three types of control statements: sequence, selection, and repetition. (T/F)
  
  
  2.There are three types of repetition statements: the while loop, the do-while loop, and the for loop.(T/F)
  
  
  
  
• 3. In while loop, if the condition is false, the loop body is executed; if it is true, the loop terminates. (T/F)
  
  
  
  
  4. The do-while loop is similar to the while loop, except that the do-while loop executes the loop body first and then checks the loop-continuation-condition to decide whether to continue or to terminate.(T/F)
  
  
  
  
• 5.The while loop and the do-while loop are often used when the number of repetitions is unspecified.(T/F)
  
  
  
  
  6. The for loop control has two parts. The first part is an initial action that often initializes a control variable. The second part, the loop-continuation-condition, determines whether the loop body is to be executed. (T/F)
  
  
  
  
• 7. The for loop is generally used to execute a loop body a predictable number of times; (T/F)
