Ii made one string variable and called it email_confirm. I used cin to get the users email but i don't know to check if the email is real.(without being connected to the internet).
For example,in PHP you can use ereg() or eregi() to see if the email is real, I mean you can see how many characters the email_confirm is made off or how many characters is used after the @ or . is used. is there any functions for this?
Now I have to write a code which would determine whether an Email address is valid or not.
In my exercise a valid address should look like this : ___@___.___.il (___ for any letters)
E.g. Valid address:
something @ something . something . il Invalid: tami @ jce . ac . uk
(without spaces of course)
Code:
#include <iostream>
#include <string.h>
using namespace std;
int isValid (char s[]) {
int length=strlen(s), ind1=0, ind2=0;
[Code] ....
It doesn't work well. It says both addresses are wrong when the 1st one isn't.
I am writing a console program for a class. I have satisfied the assignment, but I want to clear up what is mostly a cosmetic problem. The program prints a form to the console and places the cursor at a location on the form where the user inputs data. The problem occurs when the user presses the enter key without entering data. The cursor goes to the beginning of the next line. If the user enters data after this, the program functions correctly. I want to know how I can reposition the cursor if the user enters no data.
This is the code that reads one of the values:
Code:
void getHousing(HANDLE screen, MonthlyBudget &inputBudget) {
placeCursor(screen, HOUSING_ROW, ACTUAL_COL);
cin >> inputBudget.housing;
while (!validateEntry(screen, inputBudget.housing)) {
placeCursor(screen, HOUSING_ROW, ACTUAL_COL);
cout << SEVEN_SPACES << endl;
placeCursor(screen, HOUSING_ROW, ACTUAL_COL);
cin >> inputBudget.housing;
}
}
validateEntry checks that the entered value is >= 0 SEVEN_SPACES is a string of seven spaces to cover up the previous entry.
int main (int argc, char **argv) {
//int i,m;
double v1[kmax],v2[kmax],Ng,Lk[kmax],Hmax,Lmk[N],FD;
//double Lk1 = 0.0;
double x1[N];
loadImage("../sierpinski10.pgm");
printf("Bnorm[40][2] = %f",Bnorm[40][2]); //test
[code]...
Note:I am receiving error "Run-Time Check Failure #2 - Stack around the variable 'Lmk' was corrupted."
Under visual studio, this is a typical run time error,
Code:
void func(int x){
x = 3;
}
int main() {
int x;
func(x);
}
When x is passed to the function func, it is not initialized. But my question is that why it should be an error? On the other hand, if I change the definition of func a little bit like this,
Code:
void func(int& x) {
*x = 3;
}
int main() {
int x;
func(&x);
}
Now in main, x is still not initialized, but this time there isn't a run time error like "the variable is being used without being initialized. Why?
I have to write a loop assigning a variable x to all positions of a string variable and I'm stuck. I don't have extensive experience with arrays and I'm also a bit confused about C-String. The problem is below.
"Given the following declaration and initialization of the string variable, write a loop to assign 'X' to all positions of this string variable, keeping the length the same.
char our_string[15] = "Hi there!";
(Please note this is a 'C-string', not C++ standard string.)"

So I've been tasked with creating a program that checks to see whether or not a string is a palindrome. It has to remove whitespace, punctuation, and capitalization for obvious reasons. Getting some errors which I'm not sure how to correct.
On an unrelated note, while programming in the console, my cursor has turned into a gray box and replaces characters when typing, instead of pushing them forward, etc. How do I return it to normal?
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
bool isPalin(string& palin);
string cleanUp(string& palin);

I'm trying to check to see if a string from standard input is alphanumeric or not. I feel as though there may be a function for this but...
Code:
for(test_pass = i; test_pass < i; i++){
if(test_pass[i] == ('1', '2', '3', '4', '5', '6', '7', '8', '9', '0'))
printf("Your password is alphanumeric!
");
}
The compiler wasn't too happy with this.
I'm fairly new to C++ and programming in general and I'm trying to get a program to check the parameters of a binary string before converting that string to dec values. I have the user input 'num' line 39 - 42, but I want to reuse that same value in the 'void bin_to_dec()' function. Is there anyway I can use the same variable between void functions?
13 #include <bitset>
14 #include <sstream>
15 using namespace std;
16
17 void dec_to_bin(){
18 string mess;

Problem is, I'm only allowed to use stdio.h and stdlib.h. How can I accomplish this? Also, how would I check if any of the characters which were entered aren't either a number, letter, or '-'?
View 3 Replies View RelatedI am trying to add an attachment to an email in c#. I've managed to send the email with the subject, body and everything just fine. When it comes to adding an attachment it just wont attach and will send me the email without it.
This is the code I've used for adding the attachment
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment(@"C:UsersWilliamPicturesa.TXT");
MyMailMessage.Attachments.Add(attachment);
The only thing i can think of thats wrong with it is the file path even though i tried multiple paths, formats, using \ instead of @ so i just dont know.
If I wanted to learn about how to create an email server from scratch using C++ where would I go online. I am probably in way over my head but I figured I would give it a try anyway and see how things go.

View 1 Replies View RelatedHere is the assignment I get:
Write an email simulator that processes mail at an average of 40 messages per minute. As messages are received, they are placed in a queue.assume that the messages arrive at an average rate of 30 messages per minute.messages must arrive randomly.
Each minute, you can dequeue up to 40 messages and send them. Assume that 25% of the messages in the queue cannot be sent in any processing cycle.use a random number to determine whether a given message can be sent. If it can't be sent, enqueue it.
Run the simulation for 24 hours, At the end of the simulation, print the statistics that show:
-The total messages processed.
-The average arrival rate.
-The average number of messages sent per minute.
-The average number of messages in queue in a minute.
-The number of messages sent on the first attempt, the number sent on the second attempt, and so forth.
-The average number of times messages had to be requeued (do not include the messages sent the first time in this average)
Well, actually I've done a part of the coding. But how to continue it. And here is my code :
#include <iostream>
using namespace std;
#define SIZE 40
class Queue {
int queue[SIZE];
int head, tail;

Also, if it is possible to find the actual email domain, such as:

My first question is:
What are good/bad practices of creating an email scraper? The last thing I want to do is piss people off. Are there any laws/regulations that my program should conform to?
The second question:
It's easy to fetch a list of emails from a website/document.. But what if I wanted to associate something like a Name, an Address, and a Phone Number? I'm sure I could use RegEx to extract all of that info no problem, but how do I know which email to associate the Name, Address, and Phone number with? Is that even possible?
I'm trying to create this for my marketing team. We get hundreds of PDF documents sent to us per month, all containing lists of client emails and contact information. We also get directed to company staff directory websites a lot, and would like to be able to extract the information from them without having to copy/paste each element in the list, which is how my company is doing it now. We'd much rather be able to click a button and have a program automate these tasks for us.
