CHAPTER I – PLANNING PHASE 1. Preparing the System Proposal 1. Abstract His Way Internet Café uses a manual system for monitoring the time-in and time-out of every customer and for recording the services and the amount they purchased; therefore as the proponents‚ we would like to propose a computerized time monitoring and sales system that was developed through the studies we conducted. This system provides an efficient and effective way of monitoring the time-in and time-out

Problem 1:Input names of students from the user‚ terminated by ZZZ‚ andcreate a data file GRADES with records of the form:student (string)‚ test1 (integer)‚ test2 (integer)‚ test3 (integer)In this file‚ all test scores should be set equal to 0. Main Program Open GRADES Declare Name as String Call Write Grades Module Close GRADES End Main Module Write Grades Module Display "Enter Student’s Name‚ ZZZ to quit” Input Name While Name <> "ZZZ" Write Name to GRADES Write "0 0 0" to GRADES Write newline

number because it can be expressed as 5 or 5.0 and therefore it is a terminating decimal. 2.45 is a rational number because it is a repeating decimal. Irrational Numbers -An irrational number is a number that cannot be written as a fraction of two integers. -Irrational numbers written as decimals are non-terminating and non-repeating. Note: if a whole number is not a perfect square‚ then its square root is an irrational number. Caution! A repeating decimal may not appear to repeat on a calculator

any code written in the old version does not compile under VB. NET. Like all other . NET languages‚ VB. NET has complete support for object-oriented concepts. Everything in VB. NET is an object‚ including all of the primitive types (Short‚ Integer‚ Long‚ String‚ Boolean‚ etc. ) and user defined types‚ events‚ and even assemblies. All objects inherits from the base class Object. VB. NET is implemented of Microsoft’ s . NET framework. Therefore it has full access all the libraries in
