Implement a solution to the critical section problem for 2 processes using mutex locks. Specifically in pthreads using pthread_mutex_trylock.
You are provided with code in thread-template.c (available on the class hints web page) which does not work correctly, but has the necessary pthread Unix thread calls to start up two threads from the main process. Remember that all global memory is shared among threads of a process. Both threads need to count to 2,000,000 which means a correct overall count is 4,000,000. Threadl needs to be modified so that every time it sees (counter- > value%100) == 0 it increments counter- > value by 100. That counts for an 100 individual updates. You also need to keep track of how many times this happens and report it.
Use the POSIX implementation of threads. You will need to look at the pthread_create, pthread join and threads manual pages. A tutorial and the man pages are here: https://www.yolinux.com/TUTORIA LS /LinuxTutorialPosi xThreads. html
Time your code with getrusage. This is for a comparison project. It will look something like the following. The first four lines are what you need to set this up.

In this C programming assignment I would like for comments to be added to the code. Templates 1-3 have the code that need to be used for the new code. Implement a solution to the critical section problem for 2 processes using mutex locks.
Write a C++ program that uses user-defined functions to read three integer numbers from the user, compute the summation, difference, and product of these numbers, and print the results on the screen.
The Imperial system of measurements uses feet and inches for length, where 1 foot is equal to 12 inches. Write a class named Imperial that will represent distance measurements in feet and inches. Your class should include the following.
Write a function named intervalSum. This function must not accept arguments but it will ask the user to input two integers m and n and calculate and display the sum of all the integers from min(m, n) to max(m, n)
Write an entire C++ program that reads a positive integer entered by an interactive user and then prints out all the positive divisors of that integer in a column and in decreasing order.
The program should then output each candidate's name, the number of votes received, and the percentage of the total votes received by the candidate.
Please correct the errors with replacement lines beside it. And then give short notes on why it is wrong.
Write a recursive function, vowels, that returns the number of vowels in a string and write the definitions of the functions to overload the operators defined in parts a to c.
