arc function of c graphics

C program to draw Arc in C Graphics.

Syntax of arc in c graphics is arc(int x, int y, int starting-angle,int

ending-angle, int radius);.

Arc is used to draw circular arc.

It takes 5 arguments, all of the int type.

First two arguments define the center of the arc to place on the screen.

hird and fourth arguments are starting and ending angles of the arc.

Fifth argument is the radius of the arc in pixels.

!ar function of c graphics

C graphics program to draw !ar.

Syntax to draw a !ar is bar(int left,int top,int right,int bottom)

"ar is used to draw rectangular !ar.

It takes # arguments, all of the int datatypes.

First two arguments are left$top corner of the !ar

%ast two arguments are right$!ottom corner of the !ar.

bar3d(int left.int top,int right,int bottom, int depth,int topflag)

!ar&d is used to draw & dimensional rectangular !ar.

It takes ' arguments, all of the int datatype.

First two arguments are left$top corner of the !ar.

hird and fourth arguments are right !ottom corner of the !ar.

Fifth arguments is for specified depth of the !ar in pixels.

Sixth argument is for determines whether a & dimensional top is put on the

!ar or not.(if it is non )ero then it put other wise not.*

Circle

C program to draw a circle in c graphics.

Syntax of drawing circle in c graphics is circle(int x, int y, int radius).

he first two arguments are used to define center of the circle in x and y

co$ordinates.

hird argument of the circle is its radius in pixels.

c graphic program to draw polygon.

drawpoly function is used to draw polygon it may !e triangle, rectangle, hexagon,etc. In drawpoly function it will takes two argument first argument is num i.enum!er if points or +ertices and that is ( num - *. And another is an array ofpoints which gi+es the x and y coordinates of the point or +ertices of the polygon.In which array of polypoint is ( num / * where num is num!er of points or+ertices.

General syntax of polygon : drawpoly( int num, int polypoint);

For example we need to draw rectangle using drawpolyfunction than the first argument num is num!er of +ertices - that is 5 and thearray of polypoints contain num / elements so in rectangle num is 5 andpolypoint are 5 / 0 -1.

C program to draw ellipse in c graphics

Syntax of ellipse is

ellipse(int midx,int midy, int startingangle, int endingangle,int radiusx,int

radiusy);

2llipse is used to draw an elliptical arc.

2llipse takes ' arguments, all of the int type.

First two argument define the center of the ellipse to place on the screen.

hird and fourth argument are starting and ending angles of the ellipse.

Fifth argument is the radius of the ellipse in x axis and sixth argument is

the radius of the ellipse in y axis.
