OS Producer Consumer Problem using Semphore C Program

Program Name	Write a C Program for Producer consumer problem.
Theory	Producer consumer problem is a synchronization problem where producer, consumer are processes. where producer produces items and consumer process consumes items produced by producer. Items produces by producer are keepen in a buffer and its fixed size from where consumer process consumes items.
Program	#include<stdio.h> int main() { int buffer[10], buffersize =10, in=0, out=0, producer, consumer,choice=0; while(choice !=3) { printf("\n \n 1.producer \t 2.consumer \t 3.Exit"); printf("\n Enter your choice: "); scanf("%d",&choice); switch(choice) { case 1: if((in+1)%buffersize==out) printf("\nBuffer is Full"); else { printf("\nEnter the value: "); scanf("%d", &producer); buffer[in] = producer; in = (in+1)%buffersize; } break; case 2: if(in == out) printf("\nBuffer is Empty"); else { consumer = buffer[out]; printf("\nThe consumerd value is %d", consumer); out = (out+1)%buffersize; } break; } } }
Input	1.producer 2.consumer 3.Exit Enter your choice: 2 Buffer is Empty 1.producer 2.consumer 3.Exit Enter your choice: 1 Enter the value: 10 1.producer 2.consumer 3.Exit Enter your choice: 3
Output	1.producer 2.consumer 3.Exit Enter your choice: 2 Buffer is Empty 1.producer 2.consumer 3.Exit Enter your choice: 1 Enter the value: 10 1.producer 2.consumer 3.Exit Enter your choice: 3
