How do you draw a line using C graphics?

its very easy just include the graphics directory in your program...

out put a dot on the screen.... in loop like..

Horizontal line from point A(x1,y1) B(x2,y2) start to out put the point from x1,y1 and then evry next loop keep y1 the same and increment x1 by 1.

Thanks

There is one more function in graphic library of C++, that is line().

It has four arguments of int type.

line(starting x coordinate, starting y coordinate, end x coordinate, end y coordinate);

setlinestyle() and setlinecolor() can be used for different line colors and line styles.

How a pure sine wave inverter works circuit diagrams?

Filter the output with a low-pass filter whose cut-off frequency is less than 120 Hz.

That process removes the energy at harmonic frequencies from the output waveform,

leaving only the energy at 60 Hz.

What is the source of apis?

In homeopathic medicine, apis is used as a remedy for many symptoms similar to those of bee stings.

Why is hyper text markup language a good language for the world wide web?

All the languages are "Good".

But Hypertext Markup language is by far the easiest to learn.

When using FiOS does telephone voice communication share the fiber optic cable?

Yes, but it's at a different frequency than your internet. Chances are before you got FiOS your internet and phone still used the same fiber optic cable.

What is an Intel embedded processor?

A processor which is embedded into the motherboard, therefore the CPU cannot be interchanged just like a normal socket style CPU can. They're usually found in portable devices such as watches and MP3 players, and also in industry such as traffic lights and power station controllers.

What are the disadvantages of using layered approach?

Like peeling an onion, you will cry when you go through the layers!

Each layer has its own functionality and the interfaces between adjacent layers. It would be necessary to construct and interpret these in-coming and out-going requests to accept and pass onto the next layer, and hence adding some storage and processing time to the request - less efficient.

What is compile time?

Compile Time: In longer form, you might say, "at the time of compiling", or, "when the program is compiled".

When you compile a program, the compiler applies various processes to your source code in order to generate the executable files. These are actions that happen "at compile time".

Other actions happen when you actually run the finished program. These actions are said to occur, at, or in, "run time".

What is the concept of hacking?

Hacking is the practice of understanding the workings of a system. Hackers do not Break into systems, do anything illegal, or unlawful.

seriously thou... DONT DO THAT.. its a joke

you don't destroy a hacker, you just protect yourself from one.. its called a firewall or antivirus

Which tools can be used to create prototypes?

Prototypes are normally built in a similar way to the final product however parts may differ slightly as they aren't always produced on a production line they are one off's made by hand or 'compatible' parts may be used instead to lower the cost of prototyping as it is a very expensive process.

Rapid prototyping uses 3D printing technologies to make prototype parts, this process also allows for no assembly of parts as they can be printed in place thus further speeding up the prototyping process. In some cases the material used isn't final but the process takes only hours compared to traditional weeks-months and can be used to test the fitting, visual appeal and dimensional properties of the product wanting to be prototypes.

In some cases computer modelling is used to make a prototype as you can test a design without ever having to build it physically. This has its draw backs of requiring large amounts of computing power and the models may require refinement to accurately reflect real scenarios.

What is one disadvantage of the internet?

Some of the negative impacts of internet of society are the quick spread of vices, because most of the ills in society tend to go viral on the internet. People quickly take up the wrong role models because of the glorification of societal vices.

How much does broadband internet cost?

It depends upon the services that you wish to use. Dial up service can be free, but is exceedingly slow. On top of this, it relies upon you having a phone line.

Other internet services are faster, but vary greatly in cost. For example, I have cable internet which gives me 18 mbps download speed and 1 mbps upload speed with a total bandwidth cap of 250 GiB per month, and costs me $40 a month.

A T1 line, however, gives 1.544 mbps and yet can cost several hundred dollars a month! While this may seem like a horrible deal compared to cable internet, the advantage to a T1 line is that the T1 line generally comes with a service level agreement - guaranteeing you access to this bandwidth. These are generally leased out to businesses who need to guarantee that they have this internet access for 99.9% of the month.

A cable operator, on the otherhand, might only guarantee you internet access at the advertised rate 40% of the time.

What is the HTML tag for a background?

There is no HTML tag for a background as such. You put in backgrounds by using the attributes of certain tags, depending what you want to put a background on and how you want to display the background. You can also use styles to do it. You can have a colour or an image as a background. The bgcolor attribute is used in a lot of different tags to put background colours on things. So if you wanted the background colour of your page to be red, then you would have the Body tag with the bgcolor attribute like this:

If you wanted an image as the background to your page, you'd have:

Using styles you can do more complicated things with backgrounds. For example, you can use a style to put a background on a paragraph in different ways:

This paragraph will have your image as a background repeating horizontally.

Your paragraph text goes here

This paragraph will have your image as a background displaying only once.

Your paragraph text goes here

Those are just 2 ways, but there are lots more, and they can be applied not just to paragraphs but to other structures like the body or a table or whatever you want.

How can you make a list that lists the items with bullets in HTML language?

Like this:


  • first entry
  • second entry
  • ...


'ul' is 'unordered list', using bullet points. 'li' is an item in the list.

See related link to w3schools, they have a nice overview of all the HTML tags.

How was the concept of the Internet developed?

The concept of the Internet was developed during the Cold War. It was meant as a way for scientists and other "important" people to be able to connect and communicate using high-speed lines, no matter where they were.

Can you run 240v machine on single phase?

In general, no don't try it. The result will either be damage (e.g. overloaded motor burnout) to the appliance or a severe reduction (e.g. an electric heater giving off only 1/4th its rated heat) in its performance.

How long did it take to build the underwater portion of the golden gate bridge?

The original Sunshine Skyway Bridge was constructed in 1954, but destroyed in 1980. The new bridge took five years to build and construction took place from 1982-1987.

What is the difference between power transformers and pulse transformers?

A 'voltage transformer', together with a 'current transformer', belong to a class of transformers called 'instrument transformers', whose purpose is to enable high voltages and currents to be safely measured by reducing their values to lower levels, while electrically-isolating these high voltages/currents from the measuring instruments. These transformers are also used to provide input to protective relays.

A 'power transformer' is a transformer used in the electricity transmission and primary distribution systems, whose function is to either step up generated voltages (11 - 25 kV in the UK) to transmission levels (400 kV in the UK), or to step down these high voltages at 'load centres', such as towns and cities.

If 1 foot is 0.305 meters how many feet are there in 305 meters?

There are 1,000.65617 feet in 305 meters.

305 meters x 3.2808399 feet/1 meter = 1,000.65617 feet

1 meter = 3.2808399 feet

Direct Conversion Formula305 m*

1 ft

0.3048 m
