Use your code from p$1.$c and implement a timer which will count how many seconds each thread has taken. Print out the following:

$1.$ Thread $1$ duration $(1$ Marks$)$

$2.$ Thread $2$ duration $(1$ Marks$)$

$3.$ Total duration $($how long it takes both process to complete$)(1$ Marks$)$

$4.$ Average time taken for a process to complete $(1$ Marks$)$

In addition, modify the code to use IPC share memory$($pointers$)$ to pass a long variable from the parent to child process and print it in the child process.

$1.$ For Thread $1$ pass and print the number $1.(3$ Marks$)$

$2.$ For Thread $2$ pass and print the number $2.(3$ Marks$)$

Expected Output:

Shared memory Thread$1$ value: $1$

Shared memory Thread$2$ value: $2$

thread$1$ took $0\mathrm{.}000075$ seconds to execute

thread$2$ took $1\mathrm{.}533661$ seconds to execute

thread$1$ and thread$2$ took $1\mathrm{.}533661$ seconds to execute

average time taken was $0\mathrm{.}766830$
