You can work on this homework in pairs. You need to provide a text file containing the C program that solves the problem below. The deadline is 4/21/16 at 11:55 p.m.

Problem 1

Create the program below and run int.

/* hw10.c
   your name here

   this program prompts the user for a string
   and displays it back.
*/

#include <stdio.h>

int main() {
  char s[100];

  //--- get a string of chars ---
  printf( "Enter a list of email addresses, separated by spaces: " );
  gets( s );

  //--- display it back ---
  printf( "You have entered: %s\n\n", s );

  return 0;
}

Don't worry if the compiler gives you a warning indicating that gets() is dangerous. It's fine for us right now. This program is the seed for the program you have to write. <r />

Assignment

<r /> Write a program that will have the following features:

1. it will read a string from the user (as shown above),
2. the string will contain email addresses separated by spaces (one or more spaces between each address)
3. it will print the name of each person, without the text following the @-sign, and
4. it will skip the first character of each name. For example if the email is dthiebaut@smith.edu, it will print only thiebaut.

Example of User Interaction

Enter a list of email addresses:  rdoc@disney.com lgrumpy@disney.com shappy@castle.com nsleepy@smith.edu zbashful@cnn.com nsneezy@winter.org  ddopey@cnn.com

doc
grumpy
happy
sleepy
bashful
sneezy
dopey

Assumptions

• The string entered by the user will never be longer than 100 characters.
• The string entered by the user will contain at least 1 address, and potentially several.
• All email addresses contain one @-sign

Submission

Submit your program on Moodle, as a text file, in the HW 10 section.
