in c programming

please provide us with a code that is not the same as the other chegg answers :

#include #include #include #include #include

void ChildProcess1(int *a); void ChildProcess2(int *a); void ChildProcess3(int *a); void ChildProcess4(int *a);

void main(int argc, char *argv[]) { int shmid; int *total; pid_t pid; int status;

shmid = shmget(IPC_PRIVATE, sizeof(int), IPC_CREAT | 0666); if (shmid

total = (int *) shmat(shmid, NULL, 0); if ((int) total == -1) { printf("shmat error (server) "); exit(1); }

*total = 0;

printf("Server is about to fork a child process... "); pid = fork(); if (pid

printf("Server has detected the completion of its child... "); shmdt((void *) total); printf("Server has detached its shared memory... "); shmctl(shmid, IPC_RMID, NULL); printf("Server has removed its shared memory... "); printf("Server exits... "); exit(0); }

void ChildProcess1(int *a) { *a = *a + 100000; printf("From Process 1: counter = %d ",*a); }

void ChildProcess2(int *a) { *a = *a + 100000; printf("From Process 2: counter = %d ",*a); printf("Child with ID: %d has just exited ",getpid()); } void ChildProcess3(int *a) { *a = *a + 100000; printf("From Process 3: counter = %d ",*a);

} void ChildProcess4(int *a) { *a = *a + 100000; printf("From Process 4: counter = %d ",*a);

}

-------> not like this one because it is not correct

please make it more clear

In this assignment, you will create 4 processes. Each of these processes will share a variable called "total". Each will increment the variable "total" by one 100,000, 200,000, 300,000, and 500,000 times respectively. Make sure that only the newly created child calls the function "process#0" After all the children have finished, the parent process should release the shared memory and terminate. Use the "wai" function so that the parent knows precisely when each of the children finishes. The parent should print the process id of each child as the child finishes execution. Then it should release shared memory and print "End of Program" You need to run program several times and analyze your observations (write report). Sample output From Process 1: counter 270547. From Process 2: counter 347860. From Process 3: counter 400001. From Process 4: counter 500000. Child with ID: 2412 has just exited. Child with ID: 2411 has just exited. Child with ID: 2413 has just exited. Child with ID: 2415 has just exited
