History Of C..

In the beginning was Charles Babbage and his Analytical Engine, a machine he built in 1822 that could be programmed to carry out different computations. Move forward more than 100 years, where the U.S. government in 1942 used concepts from Babbage’s engine to create the ENIAC, the first modern computer. Meanwhile, over at the AT&T Bell Labs, in 1972 Dennis Ritchie was working with two languages: B (for Bell) and BCPL (Basic Combined Programming Language). Inspired by Pascal, Mr. Ritchie developed the C programming language.in this post we learn how to display mouse pointer in c language console application .

 

C program which display mouse pointer and position of pointer.(In x coordinate, y coordinate)

#include <"dos.h">
#include <"stdio.h">
#include <"conio.h> 
void main()
{
     union REGS i,o;
     int x,y,k;
     //show mouse pointer
     i.x.ax=1;
     int86(0x33,&i,&o);
while(!kbhit()) 
{
     i.x.ax=3; //get mouse position
     x=o.x.cx;
     y=o.x.dx;
     clrscr();
     printf("(%d , %d)",x,y);
     delay(250);
     int86(0x33,&i,&o);
}
getch();
}
