Hav an example with an int pointer,
assume compiler allocates two bytes for an int.

int *iptr, iArray[3] = {1, 2, 3};
/*say the iArray starting address would be 1000*/
iptr = iArray[0];
/*When u r trying to do iptr++ then it will point to 1002
(two bytes for an int) where element 2 available.
cos compiler knows how many bytes has two increment*/
iptr++;

Now come to void:

void pointer is generic pointer which can be point to any
kind of data types.

void *ptr;

/*When u r trying to do ptr++, since it is void pointer, it
will not know exactly how many bytes has to be incremented.
So that arithmatic operations not possible with void
pointer.*/

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.
