Programming involves the study of computer languages to build applications. Visual Basic is a tool created by Microsoft for building graphical user interface (GUI) applications easily. Flowcharts and algorithms are used to represent step-by-step instructions to solve problems. Programming concepts include operators, variables, loops, input, processes, conditions, and output. For example, a program may input variables, perform a calculation, check if the result is less than 100, and output or repeat the process accordingly.
Introduction to programming
- 1. Introduction to programming What is programming? Itdeal w/the study of computer language. What is visualBasic? Itis a tool created by Microsoftto build a computer application in a user- friendly environment that supports GraphicalUser Interface(GUI) Flowchart- A graphicalreprentation of step by step instructions to solvea problem. Algorithm- A set of step by step instructions to solvea problem. Operator – An engine used to performlogical and Mathematical operations. Variable- A memory storage/container Loop- An Action that repeatedly and continuously performuntil a certain condition is done. Flowchart Algorithm Variable Star preparation Ex. 1 X= 5 Y =6 Z=X+Y Input collection of Print=? the thing need Ex. 2 X= 5 Y = 6 ex.variable X,Y Z= X+Y Process Z = X+Y Is?less than 100? Yes or no If true than report the Condition condition : operation Else if false Is Z less than 100?Yes or no Display? Then end the operation
- 2. Output If yes ,than repeat the input else if no display result End End the operation มติพรอัมพรรัตน์ม.6/4เลขที่22
