EXPERIMENT 3TITLE C LANGUAGE PROGRAMMINGOBJECTIVES At the end o this lab session! the student should be able to"

#$ Create and manage Project C programming language$%$ E&plain and Construct Basic '(O and )imple delay $

*$ E&amine the structure o C program or P'C #+$

MATERIAL ANDAPPARATUS

E)P'C,-C Trainer board ! Personal Computer .ith /P0AB 'DE! )erialBootloader and! P'C#+1,23%% Datasheet$

THEORY As the scale o microcomputer based systems has increased over theyears! productivity and maintainability using Assembly language hasbecome an issue$ As a result! C language has become a popularalternative$

The ollo.ing e&plains the main eatures o the C language anddescribes ho. to .rite a program in 4C4$

Feat!e" #$ t%e C La&'a'e5#6 An easily traceable program can be .ritten$

The basics o structured programming! i$e$! 4sequential processing4!4branch processing4! and 4repeat processing4! can all be .ritten in acontrol statement$ 1or this reason! it is possible to .rite a program.hose 7o. o processing can easily be traced$

5%6 A program can easily be divided into modules$A program .ritten in the C language consists o basic units called4unctions4$ )inceunctions have their parameters highly independent o others! a

program can easily bemade into parts and can easily be reused$ 1urthermore! modules.ritten in the assembly language can be incorporated into a Clanguage program directly .ithout modi8cation$

5*6 An easily maintainable program can be .ritten$1or reasons 5#6 and 5%6 above! the program ater being put intooperation can easily bemaintained$ 1urthermore! since the C language is based on standardspeci8cations5A9)' standard59ote66! a program .ritten in the C language can beported into othertypes o microcomputers ater only a minor modi8cation o the sourceprogram$

PROCEDURES)

EXERCISES 1 *CREATE NE+ PROJECT,

Ater 8nished install the /P0AB 'DE! .e are going to sho. you ho. to create aproject using it$ There is

just a e. simple step to ollo. on ho. to create it$ Please ollo. the step belo."

#$ o to to /E9 BA= and click P!#e.t- / P!#e.t +a!2

%$ Click Ne4t/ $ On the Device menu! choose PIC1F65788 because .e are goingto use thisP'C /C or coming project$

,$ Ater that! choose a destination .here the project you create to be save as$ Andalso the projectname$ Ater that! click NEXT/$

2$ 'n step ,! there are no e&isting 8le to be added so .e can skip this step by justclick NEXT/ FINISH

Ater that! a project are created .ith the project name you added earlier$
