C++ :: Write A Password Prompt That Gives A User Only Certain Attempts

Mar 6, 2015

I'm trying to write this c++ programe:

Write a password prompt that gives a user only a certain number of password entry attempts, so that the user cannot easily write a password cracker.

Using FOR Loop. I know this can be easily done using while loop. But I want to know how to do it with for loop aswell.

Here is what I have so far:

Code:
#include <iostream>
#include <string>
using namespace std;
int main ()

[Code] ....

I don't see where the problem is.. The program just executes and does nothing.

C :: Program Attempts To Encrypt A File Using XOR Operator?

Mar 18, 2013

My program attempts to encrypt a file using XOR operator. However, when I attempt to encrypt a file, it says "Error in reading file", (a printf function I set up if the program could not read the file, obviously). The problem is that I don't know what's causing this. Instead of encrypting the file, it just deletes all the characters in it, so I put in a fprintf to put place some text into the file. Here is the code:

Code:

#include<stdio.h>
#include<string.h>
int encryptd(FILE *);
int main(void)
{
FILE *fileptr;
int recode;
char fname[25];

C++ :: Best Way To Split Main Program?

Apr 26, 2013

I need to split my main() function into two separate functions.Where would the best place be to split it up?

* Read a text file whose name is given on the command line, and for each word:
* if it is an integer, insert it into an array in sorted order
* if it is not an integer, insert it into an array of words.

* Notes: converted to use C++ strings, because C strings are messier.
* Need to grow arrays, need to insert in sorted order.
* Growing arrays might be done the way we grew a C string:

* bigger = new <type> [size+1]
* for(i=0; i<size; i++) {
* bigger[i] = oldarray[i];

C# :: Split String With Boolean

Nov 19, 2014

I have my Arduino send the following string every second:

69.4,69.4,69.4,69.4,69.4,69.4,8.42,100,100,50,50,20,16,10,14

and i currently have my C# code split it and send the values to corresponding text boxes:

// SERIAL READS:
private void myport_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e) {
string RxData = myport.ReadLine();
this.BeginInvoke(new LineReceivedEvent(LineReceived), RxData);

[Code] ....

Now if i were to add true/false values to my arduino string, im not sure to read it. I would like the bool values to enable/disable led jpegs to simulate output status.

rly1_led.enable = newData[15];// if true

Ive tried everything and just cant figure it out. This is my first C# project.

C :: Split Array Into Sections Of 2 Values

Mar 16, 2013

i want to split the array into sections of 2 values, recursively. the objective its to do the average.i have this input and output, that its correct:

> media_recursiva a 1 a 2 a 4 a 5 a 2 a 3 a 5 a 6
1.000
1.500
3.000
3.500

("a 1" means add the value 1)

but mine its wrong, it gives to me this:

1.000
1.000
2.500
3.000

Code:

float media(int arr[], int count) {
while(count != 0){
if(count==1)
return arr[0];
else if(count ==2){
return ((arr[0] + arr[1])/2);

C++ :: Function To Split The String By Delimiter

Mar 19, 2014

How delimiter work. I need write a function that splits the string by delimiter. Function header is:

vector<string> split(stirng target, string delimiter);
for example, the code inside main calling your function
vector<string> v = split("hiAAAmyAAAnameAAAis", "AAA");
and v should come out as hi my name is

So is it something like
vector<string> split(string target, string delimiter) {
vector<string> word;
string s = "hiAAAmyAAAnameAAAis";
string delimiter = "AAA";

C++ :: Split Image To 3 Channels - Opencv Error

Mar 18, 2013

I am currently planning on splitting my image into 3 channels so i can get the RGB values of an image to plot a scatter graph so i can model is using a normal distribtion calculating the covariance matrix, mean, etc. then calculate distance between the background points and the actual image to segment the image.

Now in my first task, i have wrote the following code.

VideoCapture cam(0);
//int id=0;
Mat image, Rch,Gch,Bch;
vector<Mat> rgb(3); //RGB is a vector of 3 matrices
namedWindow("window");

[Code] ....

but as soon as it reaches the split function, i step through it, it causes a unhandled exception error. access violation writing location 0xfeeefeee.

I am still new to opencv, so am not used to dealing with unhandled exception error.

I tried adding items into the vector still error, either via push_back or general assignment i.e. rgb[0] = Rch or Bch still error.

C# :: Using Split Method To Parse Line In CSV File

Jun 6, 2014

I'm using the Split method to parse line in a csv file. The following code works if there are no commas in the text of my data.

string csvLine;
string[] splitLine;
csvLine = "Jim Borland,1234,Never dreams in code";
splitLine = csvLine.Split(',');

But if I have commas in the some of the text as below I get then wrong output. So I need split on a commas which are not enclosed in double quotes.

string csvLine;
string[] splitLine;
csvLine = ""Jim,C,Borland",1234,"Never dreams in code"";
splitLine = csvLine.Split(',');

The output I want is:

Jim,C,Borland
1234
Never dreams in code

I found this :

If your strings are all well-formed it is possible with the following regular expression:

String[] res = str.split(",(?=([^"]|"[^"]*")*$)");

The expression ensures that a split occurs only at commas which are followed by an even (or zero) number of quotes ... and thus not inside such quotes).

Nevertheless, it may be easier to use a simple non-regex parser.

But the .split gives me an error and .Split doesn't work either.

C Sharp :: How To Read And Split File As String

Apr 16, 2013

how to do this in C#. Need to connect to Oracle db, take a file from directory then read every line of the file. Lines are like this:

123234847656|8800359898818177|A|20130401 14:51:42|
123234847212||D|20130401 14:52:08|
123234847212||M|20130401 14:55:38|

Then will split as string on every '|' char and according to this flag |A|, |D| or |M| I will add/delete/modify information inside. I have trouble with this part with the connection and read/split file and check for the flag A, D or M.
