Write a C-language program that shall find the size of the two
attached files (abc.txt, xyz.txt) using interrupts. Sample output of the
desired program is shown in the form of snapshots on Page-2.
Submission
You are required to submit two files in Zip format through LMS:
This Snapshot was taken after program execution. It shows how your output shall look like. (BC00123456 is sample ID that I have used; you shall display your own ID).
Solution:
#include<stdio.h>
#include<fcntl.h>
#include<io.h>
#include<BIOS.H>
#include<DOS.H>
unsigned int handle;
void main()
{
union REGS regs;
unsigned long int size;
handle = open (“c:\\abc.txt”,O_RDONLY);
regs.x.bx = handle;
regs.x.bx =handle;
regs.h.ah = 0×42;
regs.h.al = 0×02;
regs.x.cx = 0;
regs.x.dx = 0;
int86(0×21, ®s, ®s);
*((int*)(&size)) = regs.x.ax;
*(((int*)(&size))+1) = regs.x.dx;
printf(“\nname” );
printf(“\nabc file is %d”, size);
}
Submission
You are required to submit two files in Zip format through LMS:
- Your C-language program (.c file).
- An MS Word document having screen shots of your program execution…showing your own ID displayed as given on Page-2.
