A4q2.c code:

#include  #include  #include  int sum = 0; /* this data is shared by the thread(s) */ /* Thread task */ void *ThreadTask(void *arg) { int k,m; for (k=1; k 
Consider the C program A4q2.c which is available in the Google Classroom. In this program, four worker threads are created whose names are A, B, C, D. The task for each thread is to print its name on the screen 100 times. When we run this C program, their print-out names are interleaved as shown below.
 
 
Revise the C program A4q2.c by apply the pthread mutex subroutines such that there is no interleaving. When a worker thread prints its name, it will continue until it finishes. The order that which thread prints first and next is not matter (e.x., you might have C -> B -> A -> D or A -> C - > D -> B or etc.). For example, you might have this order:
