Answer / amvel

U can use FILE pointer, to find the address of a file in ur
hard disk.

What u hav to do is, Just pass the directory of the file to
lib function fopen(), to which u wanted to know the
address, and assign the return value of the function to a
FILE pointer. Now the file pointer holds the address of the
file.

Lets, look at the below code for better clarity.

#include<stdio.h>
#include<conio.h>

void main()
{
FILE *fp ;
char ch ;
fp = fopen("C:\\Documents and
Settings\\Vadivelt\\file.txt", "w+");

/*Gives the starting adds of ur file in the hard disk*/
printf("%d \n", fp);

_getch();
}

Answer / venu

FILE *fp ; is a virtual address in library.
You need meta data to find the location on hard disk.

Struct(s) { int a; long b; } Union (u) {int a; long b; } Print sizeof(s)and sizeof(u) if sizeof(int)=4 and sizeof(long)=4

In this assignment you are asked to write a multithreaded program to find the duplicates in an array of 10 million integers. The integers are between -5000,000 to 5000,000 and are generated randomly. Use 10 threads, each thread works on 1000,000 integers. Compare the time needed to accomplish the task with single thread of execution program. Do not include the time to fill the array with integers in the execution time.
