MCA Net Technologies Q.1 Write a program that determines whether a date entered by the user is valid. The user should enter numbers for the month, day, and 4-digit year as separate values. When the user presses the "Check" button, display a message in a Label indicating whether or not the date is valid. The rules to validate a date are as follows: (1) The month must be a number between 1 and 12. (2) If the month number indicates April, June, September, or November, then the day value must be between 1 and 30. (3) If the month number indicates any other month except February, then the day value must be between 1 and 31. (4) If the month number indicates February, then the year must be checked to see if it is a leap year. A year is a leap year if the following conditions are met: If the year is evenly divisible by 100, then it must also be evenly divisible by 400 to be considered a leap year (i.e and 2000 are leap years; 1700, 1800, and 1900 are not); otherwise, if the year is evenly divisible by 4, then it is a leap year. If it is a leap year, the day value must be between 1 and 29; otherwise, the day value must be between 1 and 28. Q. Write a program to determine the total amount of money in a piggy bank. Have the user enter the number of 25 paise, 50 paise, 20 paise and 10 paise coins. Use those quantities to determine the total amount of money in rupees in the bank. A sample run of the program should look something like the following:

4 Q.2 Write a function that will take in a number up to 6 digits long and return a string expressing that number in words. For example, given , the function should return One lakh Twenty-Three Thousand Four Hundred Fifty-Six. Build a simple interface to allow this function to be tested. Q.3 A local shipping company needs a program to calculate the shipping charges for packages brought in by the customers. The shipping charge is 15 cents per ounce. The input to the program is how much the package weighs in pounds and ounces (two separate inputs - for example, 8 pounds, then 6 ounces). The output is the weight of the package in total ounces and the cost of shipping the package. A sample run of the program should look something like the following: Q.4 Write a VB program that allows a user to input the loan amount, interest rate, and number of years to pay off the loan. When the user then clicks the "Calculate" button, the program should display the monthly payment, total amount that will be paid out over the life of the loan, and the cost of credit. The form should also contain a "Clear" button, which allows a user to perform a new calculation, and an "Exit" button, which allows a user to exit the program. The form should use appropriate tabbing order and access keys. The monthly payment is computed as follows: Rate(1 + Rate) N Payment = X Loan (1 + Rate) N - 1 where Payment = monthly payment Rate = monthly interest rate N = number of payments in months Loan = amount of loan You will need to convert the annual interest rate to the monthly rate by dividing the annual rate by 12 and then by 100 (or by 1200). Convert the time in years to the number of monthly payments by multiplying by 12. The total amount paid is the monthly payment times the number of years times 12. The cost of credit is the total amount paid minus the loan amount.

5 Q.5 Write a program that finds the largest of a collection of positive numbers input by the user. The user should be prompted to provide numbers until 1 is entered. At that time, the largest number should be displayed. Q.6 Write a program that will allow a user to enter an initial amount in a savings account and an interest rate that will be compounded annually. Have your program figure out how many years it will take for the user to become a millionaire. Notes Make sure you convert the interest rate to a percentage by dividing by 100 (for example, if the user enters "7", convert that to.07). To increase a value by a certain percentage, you should multiply by 1 + that percentage. For example, to increase an amount by 7%, multiply it by A sample run is shown below: Q.7 Write a program that determines whether or not a word or phrase input by the user is a palindrome (a word that is spelled the same way both forwards and backwards). For example, the program should be able to tell that words like "RADAR" and "DEED" are palindromes. Furthermore, the program should be able to detect that a phrase such as "Madam, I'm Adam" is a palindrome. This involves "weeding out" the punctuation and spaces in the phrase and converting the phrase to either all upper- or all lower- case before beginning the test.

6 Q.8 Write a program that will accept an integer from the user as input and then determine how many digits in that integer are threes. No string functions are permitted for this program; the problem must be solved arithmetically. Sample runs follow: Q.9 Write a VB program that simulates the basic functions and behavior of the Windows calculator program. Q.10 Start a new project. Add a textbox, a Label and a button to your new Form. Then write a programme that does the following: 1. Asks users to enter a number between 10 and The number will be entered into the Textbox. 3. When the Button is clicked, your Visual Basic code will check the number entered in the Textbox. 4. If it is between 10 and 20, then a message will be displayed. 5. The message box will display the number from the Textbox. 6. If the number entered is not between 10 and 20 then the user will be invited to try again, and whatever was entered in the Textbox will be erased Q. Add a Combo box and another button to your form. Create a list of items for your Combo Box. The list of items in your Combo box can be anything you like - pop groups, football teams, favourite foods, anything of your choice. Then try the following: Use a select case statement to test what a user has chosen from your dropdown list. Give the user a suitable message when the button was clicked. Note :- * Minor Project (IV Semester)

7 * Minor Project (IV Semester) To provide the experience in analyzing, Designing, Implementing and evaluating information system students are assigned a minor project work based on the techniques /software they have learned so far. A group of students not exceeding 4 can select a problem and develop software however an individual student can also undertake the project on his/her own. Based on the work done a project report is written under the guidance of faculty and submitted to department for valuation. This Project Report of the IV semester shall be evaluated in the department by both internal and external examiner appointed by the university as in the case of practical examination. The distribution of Marks will be as follows: 1. Project report evaluation 35 Marks 2. Viva-voce 15 marks. MCA-403 -Artificial Intelligence 1.
