        int n,fd1[2],fd2[2],pid;
        char buff[10],buff1[101];

        if(pipe(fd1)<0)
                perror("Error in 1 pipe");;
        if(pipe(fd2)<0)
                perror("Error in 2 pipe");

        if((pid=fork())==0)
        {
                if(dup2(fd1[0],0)<0)
                        perror("Error in 1 dup\n");
                if(dup2(fd2[1],1)<0)
                        perror("Error in 2 dup\n");;
                close(fd1[1]);close(fd2[0]);
                execl("/bin/bc\0","/bin/bc\0",NULL);
        }
        if((n=read(fd2[0],buff1,100))<0) /* Auto einai gia ta eisagvgika*/
                perror("Erro readin"); /*sxolia tou bc*/
        if(write(fd1[1],"10+10\n",6)<0)
                perror("Error writting");
        if((n=read(fd2[0],buff,3))<0)
                perror("Error in reading");
        printf("10+10=%s\n",buff);
        return 0;
