Sum of digit in c

-
  1. #include<stdio.h> 
  2. #include<conio.h>
  3.  int main()    
  4. {    
  5. int n,sum=0,m;    
  6. printf("Enter a number:");    
  7. scanf("%d",&n);    
  8. while(n>0)    
  9. {    
  10. m=n%10;    
  11. sum=sum+m;    
  12. n=n/10;    
  13. }    
  14. printf("Sum is=%d",sum);    
  15. return 0;  
  16. }   
Output:
Enter a number:143
Sum is=8

Enter a number:53


Sum is=8

Scan Converting a Point

-
Image
Scan Converting a Point Each pixel on the graphics display does not represent a mathematical point. Instead, it means a region which theoretically can contain an infinite number of points. Scan-Converting a point involves illuminating the pixel that contains the point. Example: Display coordinates points as shown in fig would both be represented by pixel (2, 1). In general, a point p (x, y) is represented by the integer part of x & the integer part of y that is pixels [(INT (x), INT (y).

Scan Conversion Definition

Scan Conversion Definition It is a process of representing graphics objects a collection of pixels. The graphics objects are continuous. The pixels used are discrete. Each pixel can have either on or off state. The circuitry of the video display device of the computer is capable of converting binary values (0, 1) into a pixel on and pixel off information. 0 is represented by pixel off. 1 is represented using pixel on. Using this ability graphics computer represent picture having discrete dots. Any model of graphics can be reproduced with a dense matrix of dots or points. Most human beings think graphics objects as points, lines, circles, ellipses. For generating graphical object, many algorithms have been developed. Advantage of developing algorithms for scan conversion Algorithms can generate graphics objects at a faster rate. Using algorithms memory can be used efficiently. Algorithms can develop a higher level of graphical objects. Examples of objects which can ...

History Of Computers

History of Computers The first counting device was used by the primitive people. They used sticks, stones and bones as counting tools. As human mind and technology improved with time more computing devices were developed. Some of the popular computing devices starting with the first to recent ones are described below; Abacus The history of computer begins with the birth of abacus which is believed to be the first computer. It is said that Chinese invented Abacus around 4,000 years ago. It was a wooden rack which has metal rods with beads mounted on them. The beads were moved by the abacus operator according to some rules to perform arithmetic calculations. Abacus is still used in some countries like China, Russia and Japan. An image of this tool is shown below; Napier's Bones It was a manually-operated calculating device which was invented by John Napier (1550-1617) of Merchiston. In this calculating tool, he used 9 different ivory strips or bones marked ...
