INTERPROCESS COMMUNICATION USING PIPES

PROGRAM

#include<unistd.h>
#include<stdio.h>
int main()
{
char a[10];
int pipe_pointer[2];
pid_t child;
char message[50];
pipe(pipe_pointer);
child=fork();
if(child==0)
{
printf("\n CHILD PROCESS IS WRITING!!! ");
printf(“\n Enter the string’);
scanf(“%s”,a);
close(pipe_pointer[0]);
write(pipe_pointer[1],a,sizeof(a));
}
else
{
printf(“ PARENT PROCESS IS READING”);
close(pipe_pointer[1]);
read(pipe_pointer[0],message,sizeof(message));
printf(“\n The parent has read    :\n % s”,message);
}
close(pipe_pointer[0]);
close(pipe_pointer[1]);
}
