Yea that's what i'm doing and i like using these examples to be ahead so i become advance. It's been a long time since I programmed with c ,I start to forget some.. By the way all the functions you need are in the cstdio stdio. C's gets is deprecated and isn't even available in the latest standards.
Don't use it. It's a guaranteed buffer overrun vulnerability. First thanks LB honor to have presence from someone with.. Oct 9, at pm UTC. Add Movie: when this activity is performed, the program accepts the following movie data from a Worker: movie code, title, PG rating [13, 16, MA], duration in minutes, director of the movie, type of movie [action, comedy, romance], status [active, inactive].
All movies are schedule 3 hours apart. Movies are shown from A. What i am trying to do is get a user to enter a username, check the original file i created with username and pin to see if their is a corresponding entry. Next ask the user to enter the pin and see if this matches Can any body help me to find out the logic I have a script chkcomponent.
The no of components are different in different times run Now I want this chkcomponent. Login through SFTP using username and password. I know that this can be done through public key authentication, but my requirement is to login ONLY through username and password. Please advise me!!! Also this file contain details of multiple Can we write a script to telnet to a unix server from unix with the username and password hardcoded in the script??

Go with debugger. I am pretty sure you have trailing newline charcter in the read password. And moreover, please read this. You have a buffer overflow vulnerability: thegeekstuff. Your id and p arrays are one too small to hold the correct ID and password.
Furthermore, please study how to use a debugger, as examining the input arrays would probably have shown you things going wrong. There are multiple possible problems: The first is that your scanf calls are prone to buffer overflows. If the user enters more than 7 characters for the id and more than 5 characters for p , you will go out of bounds of your buffers.
And the reason for the 7 and 5 character limits is that you forget that char strings in C are really called null-terminated byte strings. The null-terminated bit is important, and is what makes a string a string.
It does of course need its own element in your arrays. Thanks guys, it worked! I did it by increasing both the "id" and "p" arrays to 20 — Lawrence McClarence. Increasing the size of the arrays has solved the problem and works.
But it's not a good thing. It works anyway. It would be more correct to clean the buffer every time, it is a useless fuss in this program, but knowing it will be very useful in the programs you will write tomorrow. Show 4 more comments. Active Oldest Votes. Here are my own version of solution.
