C++ :: Regular Expressions Not Working?
Aug 25, 2014I have this bit of code that I found here: [URL] and at first regex would work, but then when I hit "[]" it wouldn't. Here's the code:
#include <iostream>

C++ :: Use Boost / Regex For Regular Expressions?
Sep 5, 2013So I need to use boost/regex for regular expressions. someone told me that it needs to be built. the first problem is boost doesn't tell you how to build it and the second is i did sudo apt-get install libboost something. I don't remember the exact name of the package. it installed but i dont know how i would build it when its installed.

May 22, 2014In order to parse mathematical expressions I am trying regular expressions and a recursive algorithm, but I have a problem with the four basic operations: +, -, *, /.
Trying to analyze a string like "a+(b+c)", if I use the pattern for a sum "(.+)+(.+)" the program matches it recognizing as subpatterns: "a+(b" and "c". How could I achieve the program to try also the other possibility?
I think that it would be great something like an regex_iterator which worked with regex_match instead of regex_search. I mean, an iterator that iterates over all the possible ways to match a given regular expression and a given string. This way I could loop through all these possibilities until the two subpatterns produced were correct mathematical expressions.
C :: Building NFA From Regular Expression
Oct 23, 2013I am trying to create a NFA from a regular expression. I have a grasp on reading in the regular expression and being able to make a stack from it. The part I am struggling on is mapping the characters in the regular expression to an integer indicating the variables order in the expression. I am just not sure how to go about this.
My code so far...
Code:
#include<stdio.h>
#include<stdlib.h>
#include "stack.h"
int main(void)
{
char expression[80];//array to store regular expression

C :: Cannot Use Array Name In Expressions
Nov 27, 2014Code:
int main() {
char *arr[] = {"Hello", "World", "Good", "Morning"};
display(arr);
return;
}
[code]....
The code works fine and prints the 4 strings. Where i m riddled is whether "ptr" in display function is a pointer or a string ? If it's a pointer then what is the type of the pointer? If it's an array, then as per my understanding, we cannot use an array name in expressions such as ptr++ (K&R).
C# :: Cannot Add Attachment To Email
Apr 26, 2015I 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.

C++ :: Declaring Pointers Vs Regular Variables?
Aug 9, 2013I really do not see the difference between these two declarations:
int myvariable;
int * mypointer;
It is said that when you define a pointer, instead of containing actual data, it contains a pointer to the memory location where information can be found.
But doesn't the other variable declaration do the same? It obviously doesn't have data either. And it must be stored in a memory location as well. So I do not see the difference.

Feb 1, 2015Here 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;
public:
Queue();
void Enq(int num);

C :: Printing Current TIME At Regular Intervals
Aug 22, 2013Its a code in module of my program, where I need to print current time (HH:MM:SS) at regular intervals.
Code:
#include<time.h>
#include<stdio.h>
//#include<windows.h>
void delay(unsigned int t){ // loop for some delay.
[Code] ....
But when I am running this code I expect this to print difference in time due to delay. But it doesn't enter the delay loop, why ?

C++ :: Evaluating Logical Boolean Expressions
Jan 10, 2013I am looking for a library to aid me in evaluating Boolean expressions. For example, i have an expression like this:
(1*(5+3)+9*65/5-(354*4565*5643+98) >= 12345) && ( 654*987+123 || (2345 > 23423 && 1 != 2)))
(It can also be much longer!) and would like to evaluate them to a true/false boolean.
There are tons of libraries to calculate the (numerical) result of a mathematical expression, but this is not what i want to do.

C :: Valid Email Address Check
Jul 13, 2013Now 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.
C++ :: Searching For Email Format And Domain
Feb 26, 2015I am new to C++ and programming in general. I was wondering if it is possible to use C++ to search for company email formats and domain addresses?
For example, finding the correct format like:
jsmith@carnival.com
or
johnsmith@carnival.com
or
j.smith@carnival.com
Also, if it is possible to find the actual email domain, such as:
@carnival.com
or
@carnivalcruises.com
or
@carnivalcorp.com
C# :: Associating Data With Email Scraper?
Dec 10, 2014My 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.

C++ :: Overloading Addition And Comparing Expressions In A While Loop
Apr 28, 2015I have two questions that are related to each other. The first one is about overloading the addition operator.
I have defined a struct as the following:
Code:
#include <iostream>
#include <string>
struct Sales_data {
[Code] ....
I then overloaded the I/O operators so I could print to the screen information related Sales_data.
Code:
// overload ostream in order for cout to work
std::ostream& operator << (std::ostream & out,
const Sales_data & cSales_data) {
out << cSales_data.bookNo << ", " << cSales_data.units_sold << ", "
[Code] ....
My first issue is with overloading the addition operator. Everyone works correctly except for std::cout << item << std:endl; will no not output the ISBN number only the units_sold and revenue when added together.
Code:
// addition operator rules
Sales_data Sales_data::operator + (const Sales_data & data2) {
units_sold += data2.units_sold;
revenue += data2.revenue;
return *this;
}
Now here is the code in its entirety
Code:
#include <iostream>
#include <string>
// Sales_data structure
struct Sales_data {
std:: string bookNo;
unsigned units_sold = 0;
[code] .....
After total = total + item;, I would like to print the total for this particular ISBN. However, I only get: blank, total units, total revenue where blank is where the ISBN would go but doesn't print after addition. My second question has to do with comparing the ISBN's of the books entered during the while loop. I would like to do something like
Code:
if (item_i.bookNo == item_i+1.bookNo) {
total = total + item;
} else {
std::cerr << "Books entered must have the same ISBNs" << std::endl;
}
Unfortunately, I cannot figure out how to set up a comparison of the bookNos. If I used #include <casset> in the overload + rule, it will immediately exit since I have no way to compare the ISBNs.
