What is Setlinestyle function in graphics?
setlinestyle() function in C The header file graphics. h contains setlinestyle() function which sets the style for all lines drawn by line, lineto, rectangle, drawpoly, and so on. Syntax : void setlinestyle(int linestyle, unsigned upattern, int thickness);
Why is graphics H used in C++?
h library is used to include and facilitate graphical operations in program. graphics. h functions can be used to draw different shapes, display text in different fonts, change colors and many more.
What is Outtextxy computer graphics?
outtextxy() function in C h contains outtextxy() function which displays the text or string at a specified point (x, y) on the screen. Syntax : void outtextxy(int x, int y, char *string); where, x, y are coordinates of the point and, third argument contains the address of string to be displayed.
What is line width in computer graphics?
line attributes in computer graphics Line has 3 basic attributes: Line width Line color Line type Line width: The line width depends on capability of the device to display it. In raster scan display the standard width line (or default line) is drawn with one pixel at each sample position.
How do you use Floodfill?
floodfill function is used to fill an enclosed area. Current fill pattern and fill color is used to fill the area. (x, y) is any point on the screen if (x,y) lies inside the area then inside will be filled otherwise outside will be filled,border specifies the color of boundary of area.
How many colors are in Setcolor () function in graphics?

Explanation : In Graphics, each color is assigned a number. Total number of colors available are 16.
What is graphic H?
The graphics. h header file provides access to a simple graphics library that makes it possible to draw lines, rectangles, ovals, arcs, polygons, images, and strings on a graphical window. The second step is initialize the graphics drivers on the computer using initgraph method of graphics.
How do I use graphics h?

- Add Link Libraries in Linker Setting.
- include graphics. h and Save code in cpp extension.
What is the difference between Outtext and Outtextxy?
Function outtext displays text at the current position while outtextxy displays text at the specified coordinates (x, y) on the screen.
What is floodfill in computer graphics?
Flood fill is an algorithm mainly used to determine a bounded area connected to a given node in a multi-dimensional array. It is a close resemblance to the bucket tool in paint programs. The most approached implementation of the algorithm is a stack-based recursive function, and that’s what we’re gonna talk about next.
Is floodfill DFS?
Floodfill can be implemented either with DFS or BFS, when all you care about is marking nodes with the same color. But when you also want to keep track of shortest distances, you’d better do a BFS rather than DFS.
How do I change the color of my graphics h?
The header file graphics. h contains setcolor() function which is used to set the current drawing color to the new color. Syntax : void setcolor(int color);
How do I change the background color in graphics h?
The header file graphics. h contains getbkcolor() function which returns the current background color. Syntax : int getbkcolor();
Where can I use graphics h?
Graphics programming in C used to drawing various geometrical shapes(rectangle, circle eclipse etc), use of mathematical function in drawing curves, coloring an object with different colors and patterns and simple animation programs like jumping ball and moving cars.
Why is Closegraph used?
closegraph deallocates all memory allocated by the graphics system, then restores the screen to the mode it was in before you called initgraph. (The graphics system deallocates memory, such as the drivers, fonts, and an internal buffer, through a call to _graphfreemem.)
