Given the following environment

#include

int data;
pthread_mutex_t mutex;

int main()
{
data = 0;
pthread_mutex_init(&mutex, NULL);

// Code Fragment Goes Here

return 0;
}

Write a code fragment that locks the mutex, increments the value of data by 1 and then unlocks the mutex.

pthread_mutex_lock(&mutex);
data++;
pthread_mutex_unlock(&mutex);
