<P>hey lior, your response did help me out but i have some questions. thanx. </P>
<P>i fixed the comparison using == not = and i closed the for loop with a }. i also used endl at the end of cout statements. that takes care of a few problems.</P>
<P>what do you mean by "if (num[i] == num[i]) ? You would probably want to loop over all previous inserted numbers here" ? </P>
<P>also, by the following:</P>
<P>"The two checks inside the for-loop should probably also hold for corrected numbers, so is a if-statement the right tool? What if the user types "3", and then again "3", and again..."</P></DIV>
<DIV></DIV>
<P>i was hoping that if num[i] == num[i] the program would return back to the initial cout statement prompting the user to re-enter the numbers. i now realize that the statement will always be false: if the numbers are duplicates or not the array will always equal itself and thus the out put will always be "you have entered a duplicate number."</P>
<P>back to the drawing board...any additional comments from anyone would be a great help.</P>
<P>thanx.</P>

<DIV></DIV>>Hi Peter,
<DIV></DIV>>
<DIV></DIV>>1.) Rhetoric question: where does your for-loop end?
<DIV></DIV>>2.) Don't forget to end cout << ".." statements with a << endl
<DIV></DIV>>3.) if (num[i] = num[i]) ? You would probably want to loop over all previous inserted numbers here. Don't forget to use == (and not =) for comparisons!
<DIV></DIV>>4.) The two checks inside the for-loop should probably also hold for corrected numbers, so is a if-statement the right tool? What if the user types "3", and then again "3", and again...
<DIV></DIV>>
<DIV></DIV>>hope that helps,
<DIV></DIV>>
<DIV></DIV>>Lior

<DIV></DIV>>
<DIV></DIV>>cpp freshman asks for help again...i want this program to request the user for 20 numbers within the range 10<x<100 and print the 20 numbers. if the numbers have any duplicates the numbers must be re-entered.
<DIV></DIV>>i have a parse error at the end of the program. i've read thru the program a few times but can't find it. **David, i am trying to think more about my programs and what i want them to do. i made a flow chart for this one. another question, is it possible to use rand()/rand_max in anyway in this program?
<DIV></DIV>>
<DIV></DIV>>thanx again everyone
