In formatting strings, how would I only get the decimals?
So, 1.456 would be .456(no digit before the decimal). I have seen a lot on removing the decimals or rounding to a certain place.
error is giving.
int ages = 0;
ages = int.Parse(textBox2.Text);
if(textBox2.Text == "")
{
MessageBox.Show("Age Blank ......");
}
else if (ages >= 5 || ages <= 9)
{
MessageBox.Show("age must be 5 to 9 only");
}
List<Byte> Pt_split(string plain) {
List<Byte> pb = new List<Byte>();
// Byte p;
string p;
int temp = 0;

I want to remove a particular character from a string. Say '.'. I've tried the following:
void removeDots(std::string &x)
{
std::remove_if(x.begin(),x.end(),[](char c){return (c == '.');});
}
This has the effect of removing the dots but keeping the length of the string the same, so old characters are left over at the end. Is there an extra action to do to x to make it the right size or is there a better way of doing it?
I'm working on a problem in which I've to design a program in which the punctuations should be removed from the string. For eg., if input str is: "Hello!!"; the output must be: "Hello".
I'm not sure how to remove a sub-string (if that's the right word!!) from a string. So, I designed a program which print out the punctuations. For eg., if input str is: "Hey!!"; the output would be: ! !
Here it is:
#include <iostream>
#include <string>
using namespace std;
int main (){
cout << "Enter a string" << endl;
[Code] ....
So, I want to know what should be added to this program so that the punctuations can be removed; or should I rewrite another program for that?
I have many random strings that look something like this:
" 55.343 Char 1.3825 asdf 0.1853 500 1.1359 4.0000 1 100 4.5043"
Notices how there are ints and chars and doubles in the string.
How do I remove all non-doubles for a string like this? The chars and ints may be anywhere within the string.
I'm trying to go search through my linked list for a passed string and if it matches, remove it...but obviously link everything back together properly. This is what I have so far but when i pass it to my display function, which is properly working, it goes into an endless loop
Code:
void llRemoveString(LinkedList** ll, char* string) {
LinkedList* newNode = (LinkedList*)malloc(sizeof(LinkedList));
newNode->value = string;
LinkedList* n = *ll;

How do I convert date in integer format to DateTime without using DateTime?
I have tried:
Regex regex = new Regex(@"^(0[1-9]|1[012])(0[0-9]|1[0-9]|2[0-9]|3[01])(1[789]|[2-9][0-9])dd+$");
if (regex.IsMatch(txt_fromdate.Text) == true)
{
DateTime dt = DateTime.ParseExact(txt_fromdate.Text, "MMddyyyy", null);
}
I've created a solution who exported Access reports (graphics/tables) to a Word- and a PDF-format. Therefor I use PDFSharp and PDFFocus.
The PDF document is okay. But the Word-document looks good. Only the size of the Word-document, it has to send by e-mail, is much too big (17MB).
I have to open the Word document again to change the PageSettings to be sure, that the page-margins and the print orientation are correct.
using System;
using Microsoft.Office.Interop.Word;
namespace PageSetup {
class TestPageOrientation {
static void Main(string[] args)
[Code] .....
I don't know how it works in the Word-library source. But I've tried WdOrientation.wdOrientPortrait and once I was surprised. I saw this page in Landscape-format.
I think there is something wrong with my document sections, because the documents (with a lot of tables, graphics and a image) is much too big. And that's only after using this method.
So my next question is: How can I shrink the size of this Word document?
And what do I have to do to limit the amount of format-settings in this word-document?
heres the function:
string ToString ( const char * format, ... )
{
char buffer[256];
[Code]....
these function do the same of the sprintf() function. but instead we use a variable for add the result, i want to return the result. when i use it:
string f;
f=ToString("hello world");
gives me several errors:
"error: crosses initialization of 'std::string f'"
"error: jump to case label [-fpermissive]"
I wrote the following code to solve this problem:
Read, from the keyboard, an integer greater than or equal to 1 (store it in a variable of type int).
Convert the integer to its representation in string format isolate each digit of the integer, convert it to the corresponding character (char).
Present the resulting string on the screen.
#include <iostream>
#include <ctime>
#include <cstring>
#include <ctype.h>
#include <cmath>
using namespace std;
unsigned GetNumberOfDigits (unsigned i) {
return i > 0 ? (int) log10((int) i) + 1 : 1;
[Code] ....
Why is it answering like this?
INTEGER ? 1999
STRING : œ
My problem needs to prompt the user to input an integer and then outputs both the individual digits of the number and the sum of the digits. An example would be entering 8030 and it spits out 8 0 3 0 as well as 8+0+3+0=11 and it needs to work with negative numbers.
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int base;
[Code] ....
Now I don't know if any of this is right a hint my professor gave us is that to get the fourth digit you would do base mod 10 and to get the first digit you do base divided 1000...
Code:
{
int power;
int counter=0;
int value=1;
cout << "Enter the power of 10 you want: ";

I want to convert the integer into a string.
int x = 693;
char chararr[max];
In my homework, x is unknown. but don't worry, I wont ask for the full code. I just need the part where you change the int into a string/array of char.
I'm thinking in circles from where to start?

How can I read a file that contains numbers only, but read it by three digits at a time? I have a long string of numbers and every three digits corresponds to a particular number in itself. i.e. a string of 064045154 would need to be read as '064' '045' and '154'. I need to then subtract one from each of these numbers and the new values I need to convert into their ASCII characters and place these in a new file. This is what I have (focusing on the 'Decrypt' function) but all it does is in the new file place a string of the same character repeated over and over a total number of times equal to the number of integers in the numbers file.
Code:
#include "stdio.h"
#include "stdlib.h"
#include "string.h"

I have a problem. I need to print the string called "last" in uppercase format. can you check why my program prints nothing.
Here is the important section of the code.

while (getline(infile, line)) {
string::size_type pos1 = line.find(' '); //pos1 is the position of the first space

I am creating small application using c#.net.I removed all image tag using regular expression no I want to remove all video file and flash file also in source code of webpage.

Suppose i have a very large number stored as a string, say
std::string str = "1000000000000000000000000000000000001";
And i use std::stringstream to convert it to int like this
std::stringstream ss(str);
uint64_t i;
ss >> i;
Then I would be maxed out right. so how would one practically handle things like comparison of two such numbers.
I could think of 2 approaches :
1) I can compare the numbers character by character.
2) I can put the results of ss >> i; into an array then compare each element of array
would there be any other methods??
I have a std::stringstream sstr I read data from with getline(sstr, s, ',').
Now I don't want it to cut off the leading blanks. How can I do that?

I've always been bothered when people say "don't name your variables with a leading underscore, it is reserved by the implementation", so I decided to ask this once and for all.
The actual standard says:
17.6.4.3.2 Global names [global.names]
1 Certain sets of names and function signatures are always reserved to the implementation:
- Each name that contains a double underscore _ _ or begins with an underscore followed by an uppercase letter (2.12) is reserved to the implementation for any use.
- Each name that begins with an underscore is reserved to the implementation for use as a name in the global namespace.
Unless I'm mistaken I read this as:
Words like "__foo" or "_BAR" are strictly off limits, as the implementation may have used it as a macro.Words like "_foo", when used for things such a member variables, or scoped variables on the stack are fine. The implementation only gets to use those as global functions inside mainspace.
So my question is this: While using leading underscores is generally frowned upon, is it, strictly according to the standard, wrong?
With the loop below, is there a way to display the actual number without the leading zeros (scientific notation) or will it just display 0 since there are so many leading zeros?
num = 1;
while (num > 0){
num /= 2;
}
cout << num;
I am looking to eliminate the leading zeroes of the input. The format has to stay the same and output must be as hinted in formatting.
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
using namespace std;
void process(ifstream& infile, char&ch, int&dec, int&c, int&w);

I just i would like to know how to record a string from a label to an array string ?

Below assignation? It is a bit confusing.
