Test case for 1st log:-
void main(int argc,char *argv[])
{
        int pid;

        if (argc < 2) {
                printf("enter pid of the tracee process\n");
                exit(0);
        }

        pid = atoi(argv[1]);
        fprintf(stderr,"Inside\n");
        ptrace(PTRACE_ATTACH, pid,NULL,NULL);
        while(1)
        {
                sleep(10);
        }
}

Test case for 2nd log:-
void main(int argc,char *argv[])
{
        int pid;

        pid = getpid();
        fprintf(stderr,"Inside\n");
        ptrace(PTRACE_TRACEME, pid,NULL,NULL);
        while(1)
        {
               sleep(10);
        }
}

Test case for 3rd log:-
void main()
{
        int pid;
        char *argv[2];

        fprintf(stderr,"Inside\n");
        pid = fork();
        if(pid == 0) {
                argv[0] = "/tst_pt";
                argv[1] = NULL;

                if(ptrace(PTRACE_TRACEME, pid,NULL,NULL))
                        printf("attached child\n");

                printf("going for exec\n");
                execv("/tst_pt",argv);
        }
        else
        {
                while(1)
                {
                        sleep(10);
                }
        }
}
