Programming & Languages: Computer Literacy PowerPoint Dustin Llanes Comm. 165
Introduction • A computer program (i.e. powerpoint) is really just a set of instructions, a code, telling your computer what to do when. • These programs can be really easy, or super complex. They are written in a computer language code.
Programs • Programs help your computer know what to do. A program for your computer is like creating an outline before a big paper, it helps keep you in order. • These programs need to be properly maintained to ensure their constant success.
Programs • There are many steps to designing a program.. • Set & Review goals: What is it supposed to do? • Design: Create the strategy to achieve goal. • Coding: Write the program. • Testing: Try it out with real people. • Documentation: What you did and why. How to use it.
Sample Program • Using old microsoft technology (BASIC) I have created my own sample program. 10 INPUT "What is your name: "; U$ 20 PRINT "Hello "; U$ 30 REM 40 PRINT "Goodbye "; U$ • This program will ask your name, say hello, and then say goodbye.
Computer Languages • Different computer languages are used to write different types of programs. • The computer understands these languages and translates it into the code so you don’t have to.
Computer Languages Cont. • Once the program is written, it can either be translated or compiled • Translated changes the text into code • Compiled changes the code into text
