Write a note on user defined functions.
Does a function always return a value? Explain with an example.
To secure your account, whether it be an email, online bank account, or any other account, it is important that we use authentication. Use your programming expertise to create a program using a user-defined function named login that accepts userid and password as parameters (login(uid,pwd)) that displays a message “account blocked” in case of three wrong attempts. The login is successful if the user enters the user ID as "ADMIN" and the password as "St0rE@1". On successful login, display the message “login successful”.
Write a program to check the divisibility of a number by 7 that is passed as a parameter to the user-defined function.
Write a program that uses a user-defined function that accepts name and gender (as M for Male, F for Female) and prefixes Mr/Ms on the basis of gender.
Write a program that has a user-defined function to accept the coefficients of a quadratic equation in variables and calculate its determinant. For example: if the coefficients are stored in the variables a, b, and c then calculate the determinant as b2-4ac. Write the appropriate condition to check determinants on positive, zero, and negative and output appropriate results.
Write a program that implements a user-defined function that accepts Principal Amount, Rate, Time, and Number of Times the interest is compounded to calculate and displays compound interest. (Hint: CI = P*(1 + r/n)nt)
Write a program that has a user-defined function to accept 2 numbers as parameters, if number 1 is less than number 2 then numbers are swapped and returned, i.e., number 2 is returned in place of number1 and number 1 is reformed in place of number 2, otherwise the same order is returned.
For the SMIS system extended in Chapter 6 let us do the following:
- 7.1 Convert all the functionality in Chapters 5 and 6 using user-defined functions.
- 7.2 Add another user-defined function to the above menu to check if the student has short attendance or not. The function should accept the total number of working days in a month and check if the student is a defaulter by calculating his or her attendance using the formula: Count of days the student was present or the total number of working days. In case the attendance calculated is less than 78%, the function should return 1 indicating short attendance otherwise the function should return 0 indicating attendance is not short.
Let’s peer review the case studies of others based on the parameters given under “DOCUMENTATION TIPS” at the end of Chapter 5 and provide feedback to them.
