ISY2006 – Object Oriented Programming

Write and Execute four programs based on the content of previous lectures.

You need to write and execute programs using visual c#.

 1. Write C# code to declare two integer variables, one float variable, one Boolean variable,  one char variable and one string variable and assign values, then find the addition of one integer and float variable. Then display their values on the screen.

 2. Write a program named Check Credit that prompts users to enter a purchase price for an item. If the value entered is greater than a credit limit of $5,000, display an error message; otherwise, display Approved.

 3. Write a program named Admission for a college’s admissions office. The user enters a numeric high school grade point average [GPA] (for example, 3.2) and an admission test score. Display the message Accept if the student meets either of the following requirements:

A grade point average of 3.0 or higher, and an admission test score of at least 60  • A grade point average of less than 3.0, and an admission test score of at least 80 • If the student does not meet either of the qualification criteria, display Reject.

4. Write a program named CheckMonth that prompts a user to enter a birth month. If the value entered is greater than 12 or less than 1, display an error message; otherwise, display the valid month with a message such as 3 is a valid month.
