It’s interesting.
This program reads environmental variables. It is as same as
"env" command in unix.
But program is not proper. i.e. if you pass n arguments to
program, then it reads n environmental variables only.
Try this program
void main(int argc,char *argv[],char *env[])
{
int i;
if (2 <=argc){
for(i=0;i<atoi(argv[1]);i++)
printf("\n%s",env[i]);
}else printf("\nPlease enter no. of env variables you want
e.g. 'a.out 5'\n");
}

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.
