Using the code above to write a program that accepts an integer N as a command line input and then proceeds to launch N threads within that process on Windows system.

1.Each Thread should consist of an infinite loop that prints out Thread k running where k is a Thread index (from 0 to N-1).

2.After 5 seconds of running, your main program should kill Thread 0, then after another 5 seconds, should kill Thread 1, and so on until all Threades have been terminated. At that time, your main program should itself terminate.

Ex:

when the user input N=3

the CMD will display the following:

Thread : 0 Running

Thread : 1 Running

Thread : 2 Running

(after 1 second, the CDM will display the following again)

Thread : 0 Running

Thread : 1 Running

Thread : 2 Running

(after 1 second, the CDM will display the following again)

Thread : 0 Running

Thread : 1 Running

Thread : 2 Running

(after 1 second, the CDM will display the following again)

Thread : 0 Running

Thread : 1 Running

Thread : 2 Running

(after 1 second, the CDM will display the following again)

Thread : 0 Running

Thread : 1 Running

Thread : 2 Running

(after 1 second, start to Terminate Threads, Terminate Thread 0 first, the CDM will display the following)

Thread : 1 Running

Thread : 2 Running

(after 5 second , Terminate Thread 1, the CDM will display the following)

Thread : 2 Running

(after 5 second , Terminate Thread 2, the CDM will display the following)
