#include #include #include main(int agrc,char *argv[]) {     int fd[2],pid,n,f,ch;     char buffer[2048],*cha;     if(pipe(fd)==-1)     {         printf(" problem to create the pipe \n ");         exit(0);     }     else     {         pid=fork();         if(pid!=0)         {             close(fd[0]);             f = open("hardik",O_RDONLY);             while((n = read(f,buffer,2048)) > 0)             {                 write(fd[1],buffer,n);             }             close(fd[1]);         }         else         {...

Write a program to create a pipe and share between parent and child process. Parent writes content to pipe from the file and child reads the content and display number of characters.

Write a program to create three child process. The parent process send the signal to terminate all these child processes.

By
#include #include main() {     int pid[3],status,i;     for(i=0;i     {     pid[i]=fork();     printf("\n new created child process value is :%d",pid[i]);     }     for(i=0;i     {         if(pid[i])         {             printf("for terminate the process  \n");             kill(pid[i],9);             printf("termination of the child process :%d \n ",pid[i]);         }     } } }
