Welcome to CS201!!! Introduction to Programming Using Visual Basic

Preliminaries Syllabus Windows 2000 & our lab in S104 (Sec. 1.2) Disks & folders/directories (Sec. 1.3) Introduction to Visual Basic (Sec. 1.4) Algorithm development & foundations of problem solving

Syllabus A gentle introduction to programming Problem solving & algorithm development are the emphasis Visual Basic is the tool we use: – – graphical user interface (gui) applications – – syntax & semantics Course layout – lectures, labs Course requirements

Disks, folders/directories Section 1.3 The floppy disk is accessed from drive a The hard drive of the computer on which you’re working is accessed from drive c All access can be made using either My Computer or Windows Explorer

Problems, Procedures & Computers “…the computer is ultimately dependent on the human mind to supply it with the necessary instructions to solve any type of problem.” This set of instructions is a program.

Algorithms Underlying every computer program is an algorithm. Algorithms are MODELS of the situations we wish to address. – – Usually, the “situations” are problems and we “address” them by solving them. more...

Algorithms An algorithm is an approach that is – –effective, – –precise and – –results in the solution of a given problem. What makes an algorithm good? Let us create an algorithm
