Run the following

C program

(tprog2.c) and observe the result on the screen.

Briefly

explain why we may get the interleaving messages from

the

se

two processes.

#include

void* print_i(void *ptr)

{

printf("1: I am

\

n");

sleep(1);

printf("in i

\

n");

}

void* print_j(void *ptr)

{

printf("2: I am

\

n");

sleep(1);

printf("in j

\

n");

}

int main()

{

pthread_t t1,t2;

int rc1 = pthread_create(&t1, NULL, print_i, NULL);

int rc2 = pthread_create(&t2, NULL, print_j, NULL);

exit(0);

}

3.

Add mutex lock

s

to tprog2.c

to achieve synchronization,

and

then

observe the result on your

screen.

Submit the following on Blackboard:

1) a text file (e.g. q2.txt) that includes your answer to question 2.

2.Add mutex locks to tprog2.c to achieve synchronization,and then observe the result on your screen.
