Solve the producer and consumer problem with inter thread communication (join(), wait(), sleep() etc.) modifying the given C code.
#include <pthread.h>
#include <stdio.h>
#include <string.h>
#define MAX 10 //producers and consumers can produce and consume upto MAX
#define BUFLEN 6
#define NUMTHREAD 2 /* number of threads */

/* create 2 threads*/
/* create one consumer and one producer */
/* define the properties of multi threads for both threads */
//Write Code Here
}
void * producer(int *id){
/*
- Producer stores the values in the buffer (Here copies values from source[] to buffer[]).
- Use mutex and thread communication (wait(), sleep() etc.) for critical section.
- Print which producer is storing which values using which thread inside the critical section.
- Producer can produce upto MAX
*/
//Write code here
}
void * consumer(int *id)
{
/*
- Consumer takes out the value from the buffer and makes it empty.
- Use mutex and thread communication (wait(), sleep() etc.) for critical section
- Print which consumer is taking which values using which thread inside the critical section.

Example Output:
0 produced a by Thread 0
1 produced b by Thread 0
0 consumed by Thread 1
2 produced c by Thread 0
1 consumed b by Thread 1
3 produced d by Thread 0
4 produced e by Thread 0
2 consumed c by Thread 1
5 produced f by Thread 0
6 produced a by Thread 0
3 consumed d by Thread 1
7 produced b by Thread 0
8 produced c by Thread 0
9 produced d by Thread 0
4 consumed e by Thread 1
