hey i was wondering if someone could help me with this problem. i am so incredibly and utterly confused. here it is...

write a simple phone directory program that looks up phone numbers in a file containing a list of names and phone numbers (called input.txt). the user should be prompted to enter a first and last name and the program then outputs the corresponding number, or indicates that the name isn't in the directory. after each lookup, the program should ask the user whether they want to look up another number, and then either repeat the process or exit the program. the data on the file should be organized so that each line contains a first name, last name and a phone number seperated by blanks.
use functional decomposition to solve th problem and code the solution using functions as appropriate (use a function to get the name from the user and another to check the list to locate the phone number). use appropriate comments.

if someone would help me, i would be GREATLY indebted!!!! please!!!!!

What part are you stuck on? Do you need help designing it?

Most people here won't write your code for you, but can help you get started with some suggestions. Let us know what you're stuck on, and we'll try to give you a nudge in the right direction...

well i dont know how to make it look @ the names in the list, then find out if they match what's on the list. that's a big problem. i think if i get this figured out i can do the rest....thankies!

holy crap....how long did that take you? THANKS SOOOO MUCH!!! i owe you big time, if there is anything you need, ANYTHING ask!! thankies again

>how long did that take you?
The real question is how long will it take him to realize that doing your homework for you was a mistake.

>i owe you big time
No, you don't. The code you were given would get me fired, and it'll probably get you a bad grade if your teacher has any brain at all.

now why did you alert him to the fact that he shouldn't just submit that code as his assigment?

Don't we want people who're too lazy to do their own work to get burned?

>Don't we want people who're too lazy to do their own work to get burned?
I try to avoid such things whenever possible. But you might be a sadistic prick while I'm not. Everyone is different.

let them burn once so they never burn again. One bad grade won't hurt anything but his pride but he may learn from it to think for himself.

Not sadistic, just realism.

>but he may learn from it to think for himself.
Then again, he may never come back because all we helped him do is get bad grades. Then he'll probably try again on another forum with similar success. I'd rather have someone here, where I can guide their progress, rather than elsewhere, screwing up and not learning the right lessons from it.
