Fix the following C program so it compiles and runs.

#include stdio.h

#include unistd.h

#include stdlib.h

#include string.h

#include pthread.h

#include semaphore.h

void * thread_function(void *arg);

sem_f bin_sem;

#define party_size 1024

/ definition function /

char party_area[party_size];

int main()

{

int result;

pthread_f a_thread;

void *thread_result;

result= sem_init(&bin_sem,0,0);

{

if (result != 0)

{

perror(\" the partier waits for the pledge\");

exit(exit_failure);

}

printf(\" the drink is not filled with keg\");

if(result != 0)

{

perror(\" the partier wake sup the pledge\");

exit(exit_success);

}

printf(\" the drink is filled with the new keg\");

sem_wait (&bin_sem);

}

pthread_exit(null);

}

Problems when compiling

error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘bin_sem’
In function ‘main’:
error: ‘pthread_f’ undeclared (first use in this function)
error: (Each undeclared identifier is reported only once
error: for each function it appears in.)
error: expected ‘;’ before ‘a_thread’

error: ‘bin_sem’ undeclared (first use in this function)

error: ‘exit_failure’ undeclared (first use in this function)
error: ‘exit_success’ undeclared (first use in this function)
error: ‘null’ undeclared (first use in this function)

Solution

Here is the modified version for you:

#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <string.h>
#include <pthread.h>
#include <semaphore.h>
void * thread_function(void *arg);
sem_t bin_sem;
#define party_size 1024
// definition function
char party_area[party_size];
int main()
{
int result;
pthread_t a_thread;
void *thread_result;
result= sem_init(&bin_sem,0,0);
{
if (result != 0)
{
perror(\" the partier waits for the pledge\");
exit(EXIT_FAILURE);
}
printf(\" the drink is not filled with keg\");
if(result != 0)
{
perror(\" the partier wake sup the pledge\");
exit(EXIT_SUCCESS);
}
printf(\" the drink is filled with the new keg\");
sem_wait (&bin_sem);
}
pthread_exit(NULL);
}
