i have encountered a problem with my assignment, and i have researched it on the internet, but unfortunately i didn't find anything related to that.
i am writing a simple program that takes user's input by prompt command, and parse the whole line into an array of strings by spaces between. the part i don't understand is, how to detect the end of the line.
here is my code
Code:
int *parameter[10];
int i = 0;
while(!0 && i < 10) {
scanf("%s", ¶meter[i]);
if(!EOF)
break;
printf("parameter is %s\n", ¶meter[i]);
i++;
}
if i type in this in prompt command
word1 word2 word3
here is the program's output
string is word1
string is word2
string is word3
when the program reaches here, it freezes, it cannot seem to detect it is the end of user's input

qmail-users(5) File Formats Manual qmail-users(5)NAME
qmail-users - assign mail addresses to users
OVERVIEW
The file /var/lib/qmail/users/assign assigns addresses to users. For example,
=joe.shmoe:joe:503:78:/home/joe:::
says that mail for joe.shmoe should be delivered to user joe, with uid 503 and gid 78, as specified by /home/joe/.qmail.
Assignments fed to qmail-newu will be used by qmail-lspawn to control qmail-local's deliveries. See qmail-newu(8). A change to
/var/lib/qmail/users/assign will have no effect until qmail-newu is run.
STRUCTURE
/var/lib/qmail/users/assign is a series of assignments, one per line. It ends with a line containing a single dot. Lines must not contain
NUL.
SIMPLE ASSIGNMENTS
A simple assignment is a line of the form
=local:user:uid:gid:homedir:dash:ext:
Here local is an address; user, uid, and gid are the account name, uid, and gid of the user in charge of local; and messages to local will
be controlled by homedir/.qmaildashext.
If there are several assignments for the same local address, qmail-lspawn will use the first one.
local is interpreted without regard to case.
WILDCARD ASSIGNMENTS
A wildcard assignment is a line of the form
+loc:user:uid:gid:homedir:dash:pre:
This assignment applies to any address beginning with loc, including loc itself. It means the same as
=locext:user:uid:gid:homedir:dash:preext:
for every string ext.
A more specific wildcard assignment overrides a less specific assignment, and a simple assignment overrides any wildcard assignment. For
example:
+:alias:7790:2108:/var/lib/qmail/alias:-::
+joe-:joe:507:100:/home/joe:-::
=joe:joe:507:100:/home/joe:::
The address joe is handled by the third line; the address joe-direct is handled by the second line; the address bill is handled by the
first line.
