perferable using C language or C++

other 3 pictures attached are sample programs.

Task Read the man pages of the following fanctions (you may need to run sado apt-get inetall glibe-doc conamand for these): e pthread create *pthread nutex unlock 3 partially completed prograns have been provided for you to belp you learn threads For this lab you are to create an outpat sinnilar to that of the previous lab (r-5, a/, ete.). This time you are using threals though. Since tlreads share global variabks, you may make r a glohal varialle, thus you don't have to use a file or shared memory to modify it. There are two ways to do this lab, and you may choose eit her, but yo must use altithreadig I. You can create your threads inside the loop, and use pthread_join) to coatrol the flow. Thus 10 total threads will be ereated. 2. You can make each thread have its own oop, and use mistexes and sleep)0 to coutrol the fow. Thas 2 total threads are created.
