Q1. Write an application which creates a process to execute another application in the executable file "/home/hello". Your parent process should wait the termination of the child process. Also parent should print "PARENT is WAITING" to the screen before the child process finishes. Child does not print anything to the screen except the standard output of hello application. Note that you only need to write the main method. Q2. Write a possible output of the following application (assume that all libraries are included correctly). int main () \{ pid_t n, int x=2; n= fork(); if (n>0) \} x=x+7; wait(NULL); \} else if( n==0){ execlp("/bin/ls", "ls", NULL); x=x+10; \} printf("x is \%d n,x); return 0; \}
