Acknowledgement

We are thankful to our lecture, Ms. SEETHA LETCHUMY who has a major effect on our opinion about C programming. As well for the time and energy made in making sure that we understood the basic and progressive features of C program writing. Also we would like to thanks to our fellow colleagues and home mate who aided us in comprehend and debugging some of the faults which we encountered as well.

Introduction

The C program writing language was established by Dennis Ritchie at AT&T Bell Test center in the first 1970s. It was not till the getting on 1970s, though, that this encoding language created to increase general approval and provision. In this point of view, until that period C compilers were not readily accessible for marketable usage outside of Bell Test center. To begin with, C program language develop in admiration was also stimulated on in share by the equivalent, if not quicker, progress in admiration of the UNIX OS. Talking about operating system, which was also industrialized at Bell Research laboratory, had C as its ―standard‖ program design language. Indeed, more over 90% of the OS‘s it was printed in the C language.

C encoding is a very dense language, so there isn‘t a ration of syntax to study beforehand you can code actual submissions. In malice of its succinctness and ease, it‘s also a tremendously influential language that‘s still commonly used by experts. The influence of C program writing is such that it is used for computer programmer at all stages with any level of knowledge, from expedient drivers and operating system components such as small-scale such as we have here in this assignment to large-scale applications.

How to Creating C Programs

There are 4 essential platforms in the formation of any C database as we mention here briefly: i. Editing

ii. Compiling iii. Linking iv. Executing Editing

This is the course of creating and adapting C basis code—the name assumed to the database instructions you coding. Certain C compilers introduce with exact editor that can offer a lot of support in handling your programs as well. Indeed, an editor often offers a whole setting for writing, handling, emerging, and testing your codes. This is occasionally named IDE.

(6)

Washing Machine System Page 6 Compiling

The compiler translates your basis codes into engine language and notices and reports mistakes in the compilation course. The input to this period is the case you create during your excision, which is usually mentioned to as a basis file as well. The compiler can notice an extensive variety of faults that are due to unacceptable or unrecognized database code, and also mechanical errors where, for instance, some part of a database can never be performed. The output from the compiler is recognized as entity code and is kept in records called object files, which typically have tags with the allowance.

Linking

The linker chains the numerous modules produced by the compiler from basis code files, enhances essential code components from program libraries complete as part of C program, and repairs the whole thing into an executable entire. The linker cans similarly notice and report faults, for instance, if part of your database is lost or a missing library constituent is referenced in deed.

Executing

The implementation period is where you run your database, having finished all the earlier processes positively. Unfortunately, this period can also make an extensive change of fault situations that can contain making the mistaken output or just inactive and nil, maybe crashing your PC for good amount.

Objective

Generate a scheme to controller a replicated washing machine. On the sour face of the washing machine component are some buttons and also each signified with a letter.

Case Study

We are requested to generate a organization to mechanism a simulated washing mashing consuming some buttons in which each button signified with a alphabet acceptable for the washing machine to be well-ordered that operator is to allocate On and Off pin and when the washing machine is switch on using the On and Off key which signified by O letter the operator will has the choice of deciding whether including:

i. (V) View log: if this choice is selected you can be able to understanding the washing machine process logs conferring to the previous worked.

ii. (W) Wash clothes: if this key is nominated the capacity menu will perform.

When the load capacity perform, the operator will need to control the scope of the weight which include i. (S)Small, ii. (M) medium, iii. (L) large, iv. (X) extra-large, v. (f)free load,

In view of that there is a least and last rate for each load capacity as well. Whenever the size of the clothes has been nominated, the wash menu is started and now the operator is given the choices to choice:

1. (F) full wash, 2. (W) wash, 3. (R) rinse, 4. (S) Spain.

(8)

Washing Machine System Page 8 (F) Contain of washing, rinsing and spinning. It moreover contains Sock but contingent on the collection completed in the sock menu which perform when the full wash is started. In the sock menu the user has the choices whether to choice:

i. (N) No soaking and when this has been nominated the program will continue to following menu choice (Temperature menu)

ii. (S) Sock, the system will move the operator for the total of minutes to sock and the database will continue to the following menu witch is (Temperature menu).

Temperature menu start first after either the (F) or (W) selection has been nominated and the operator will be given the selections whether to choose (H) hot or (C) cold as well. When all the essential inputs have been delivered to the washing machine‘s classification, the program offers the operator with the assessed time of implementation the wash as planned and all these specifics are kept in a view log at all.

Sample Outputs

State on and off

The overhead screen shot displays the current time and date as well as state on and off in the system. Here the operator is supposed to choice whether to on the washing machine . The operator can even see the operation time and date as shown above. Whenever operator types any word instead of O the machine would be off and ask to press O again.

(29)

Washing Machine System Page 29 Main Menu

After the user processed to the main menu, then the washing machine gives user two option witch is : W is for wash clothes and V for view the log.

(30)

Washing Machine System Page 30 View Log b

After choosing view log the user can view the last process, meaning that the operator can realize all the process that have been done, what kind of action and user can see the date and time that process has done.by pressing any key user can access again to the main menu.

(31)

Washing Machine System Page 31 Load Capacity Menu

As a result, after the user selected to the Wash Clothes then the user have to choice the size of the Load Capacity Menu as well, which could contain any one of the next five decisions. The choices including: Small, Medium, Large, Extra-large as well as Free Load.

If the operator is not assured on which size to choice has the option to choose Free Load. This means that the operator would be contingent on the machine to control the Load Capacity

grounded on the heaviness of the clothes. The weight of the wears can be an accidental generated rate but its value has to be a rational heaviness for clothes put into a machine as well. When the weight is resolute then the Load Capacity is established mechanically to Small, Medium, Large as well as Extra Large. Mention that there should be a least and full rate for each Load Capacity sort. For this situation:

1. Small is less than 2kg, 2. Medium is (2 - 4) kg, 3. Larger is (4 - 6) kg, 4. Extra-large is (6 - 8) kg.

(32)

Washing Machine System Page 32 Wash Menu

Here After the size of the load has been noticed, the Wash Menu is triggered. Then the user now gets to choice from one of the subsequent Wash Menu choices as shown overhead.

(33)

Washing Machine System Page 33 Soak or no soak

If the operator choice Full Wash would contain of Washing, Rinsing and Spinning but may contain Soak contingent on the collection made in the Soak Menu which show off when the Full Wash is triggered. Wash would contain of just washing, lacking rinsing or spinning. Though, it may contain Soak contingent on the collection made by the operator from the Soak Menu which show off when Wash is started. In the Soak Menu the

(34)

Washing Machine System Page 34 Soak

Whenever the operator chooses N, the program will continue to the following menu choice witch is Temperature Menu. If the chooses S, the system will ready the operator for the amount of minutes to soak the clothes. The operator can chose in any rate between 1 – 60 minutes as well. Once the number of minutes is mentioned the program will continue to the following menu choice – Temperature Menu.

(35)

Washing Machine System Page 35 Soak menu (more than 60 minutes)

Whenever user type more than 60 minutes the program will show the warning witch is: this time is more than 60 minutes.so user should mention the time less than 60 minutes.

(36)

Washing Machine System Page 36 Temperature Menu

This menu is started only after both the Full Wash and the Wash select has been designated. The Temperature Menu holds Hot and Cold as shown overhead. Then if the operator chooses ―H‖, hot water will be recycled for all processes from soaking to rinsing. Or other cold water will be recycled as well.

(37)

Washing Machine System Page 37 View log

This menu started after machine got all the information‘s and start to work.as you can see it gives all statistics that the user gave to the machine in the screen.

(38)

ADDITIONLA FEATURES

It shows the logs single by single in log view which styles it more contented for operator. In addition, in our program for making chance rate we took the input for the showing in the view log of the screen as well as showing in view log b.

ASSUMPTION

We were not given exact way for just out put the information in view log b that the user cannot see that what information he or she given to machine .we create the view log that user can see witch parts of options he or she took.

In additional, if user types any wrong type the system would give him or her notification that this answer is in valid. Type again correctly.

Conclusion

C is perfect programming languages that can make software design a lot of challenges. Programming in C is a talent that could finish up saving you your occupation or aid you get a healthier occupation. Now in this task the notion was to create a washing machine system by C under convinced restraints stated by the lecturer.Done all this assignment we have been fronting many problems due to our lack of information, but our determination aided us to stare forward, and apply a problematic resolving set of mind. Analysis books, considering in net, requesting from friends were all conducts that we used to exceed the problems.
