Develop a program that calculates the sum of elements of an array using POSIX threads for concurrent execution. Please write it using C++ or C. 1. Create a program that has a global array of 20 integers, you may use predefined values or generate random values. 2. Create 5 POSIX threads. Each of these will be responsible for calculating the sum of a specific region in the array. The first thread will calculate the sum of elements 0 to 3. The second will calculate the sum of elements 4 to 7, the third will sum elements 8 to 11, the fourth will sum elements 12 to 15, and the fifth will sum elements 16 to 19. 3. The main program will wait for these threads. a. Use pthread_join(3) 4. After the threads have finished, the main thread shall combine the partial sums computed by each thread to obtain the final sum. 5. The main thread shall display the partial sums from each child, and the total sum

Question

Please make sure that the program has the following

  1. Thread Creation
    1. Proper creation of the five threads.
    2. Threads access only their assigned region in the array.
    3. Properly joining on ALL threads.
  2. Thread Execution
    1. Accurately calculating the partial sums by each thread.
    2. Returning the proper value to the main thread.
  3. Collection and Display of Results
    1. Properly collecting the values from the threads and displaying the sum.
  4. Code Structure
    1. Good quality code with appropriate functions, variable names, and comments.
  5. Error Handling
    1. Checking for errors from system calls and major library routines.
    2. Proper error messages if they occur.
