Interprocess communication Using Pipes

Coding:

 #include<stdio.h>

int main()

{

int fd[2],child;

char a[10];

printf("\n enter the string to enter in to the pipe:");

scanf("%s",a);

pipe(fd);

child=fork();

if(!child)

{

close(fd[0]);

write(fd[1],a,5);

wait(0);

}

else

{

close(fd[1]);

read(fd[0],a,5);

printf("]n the string retrieved from the pipe is%s\n",a);

}

return 0;

}

Output:

[telnet50@linux ~]$ ./a.out

Enter the string to enter in to the pipe:    computer

The string retrieved from the pipe is   :    computer
