C++ :: Stringstream Consecutive White Space

Oct 1, 2013

So I have a text file named test.txt on the root of my c:/drive.

I finally managed to arrays working and reading into them, but when I started looking at the data in the array I noticed that stringstream was not "grabbing" a specified space. LINES 83-88

The text file contains the following (note that there is an intentional space after the first word):

I ' m s o r 0 y 4 D a v e , 5 12 12 12 3 7 f 11 2 i d 5 8 1 c 5 n 10 t 5 7 17 2 3 h 7 2 .

I need that space to be caught in the steam, there will always be only one space after a various first word, but I need it in my array and stringstream doesn't catch it.

if you need to run it, just copy the text to a file named c:/test.txt

When you run the code, you will see after the 3rd iteration it skips the space, is there a way to change this, so I can focus on the decryption algorithm??

#include <iostream>
#include <fstream>
#include <vector>
#include <string>
#include <stdio.h>
#include <sstream>
#include <cctype>
bool is_number(const std::string& s){
std::string::const_iterator it = s.begin();

[Code] ...

C++ :: Stringstream - Split User Input Into Words Separated By Space

Apr 20, 2014

I trying to get input from the user and split into words that separated by a space.

string s = "1 2 3";
istringstream iss(s);
int n;
while (iss >> n) {
cout << "* " << n << endl;
}

The code above works fine but i want to get the string from user. the code below only prints the first word and trashes rest of the words in the sentence.

string s ;
cin>>s;
istringstream iss(s);
string n;
while (iss >> n) {
cout << "* " << n << endl;
}

C# :: Clear White Space On Random Tile Map

Mar 14, 2015

I've got myself a 2d array

int[,] map = new int[100,100];

I've populate that will a bunch of 1's and 0's. The 1 represents a wall, and a 0 is dirt.

I'm looking for a way to clean up my blank spaces outside of my walls. Any algorithm I can use to identify these big areas and replace them with a '1'

for (int y = 1; y < map.GetLength(1) - 1; y++) {
for (int x = 1; x < map.GetLength(0) - 1; x++) {
// Inside here is where I was hoping to archive my work
bool draw = true;
foreach (Room room in rooms)

[Code] ....

Attached is an example of my output.As you will be able to see, there is a lot of brown. I want to fill the brown with walls, but leave space for a path between the rooms.The 'draw' bool is true when I'm outside of a room, just so I don't start throwing walls inside my room.

Example of what the array would look like (for those who don't know)

int[,] map = new int[100,100]
{
{0,1,1,1,1,1,0},
{0,1,0,0,0,1,0},
{0,1,0,0,0,1,0},
{0,1,0,0,0,1,0},
{0,1,0,0,0,1,0},
{0,1,1,1,1,1,0},
};

C++ :: Ifstream Insertion With White Space Delimited Data

Jun 21, 2013

I'm doing a project that takes in a input file with Quarterback statistics. It has their name, team, completions, sacks, touchdowns, etc. It has 16 different variables in all (17 if you count first/last name as two). So I'm trying to read them and I can't figure out how to jump to the new line after it's read the file and put the information in the variables I've created.

#include <iostream>
#include <fstream>
using namespace std;
ifstream din;
void openFile() {

[Code] ....

That's the program I've written. The loop keeps displaying the first line of the file over and over. How can I get it to go to the second line, then the third, then fourth, etc? I need it to display all the lines of the file until it reaches the end of the file.

my answer is :

#include <iostream>
using namespace std;
#include <iostream>
#include <string>

Now I am not sure if im suppose to get a msg saying : The file "Question 1.cpp" has 0 words.

im wondering is the question that im being asked, asking me to input a string of words and then the compiler when it builds and runs the program counts the word spaces.?

C++ :: How To Restore Consecutive Enumeration

May 10, 2014

I have an array of groups of numbers (I call them classes), that might look like this:

Code: static const int arr[] = {1,1,3,3};
std::vector<int> classes( arr , arr + sizeof(arr) / sizeof( arr[ 0 ] ) );

or like this

Code: static const int arr[] = {1,3,3,3,5,5,6,8};
std::vector<int> classes( arr , arr + sizeof(arr) / sizeof( arr[ 0 ] ) );

The groups of numbers are in an increasing order, but not numbered consecutively. So, would I would like to have is this

1,1,2,2

and

1,2,2,2,3,3,4,5

A loop like this

Code: for ( int i = 1; i < classes.size(); i++ )
if ( classes.at( i ) > classes.at( i - 1 ) )
classes.at( i ) = classes.at( i - 1 ) + 1;

does not work, because it changes the preceding value in the group, thus destroying the group. How would you do it?

C/C++ :: Stringstream Doesn't Pass Its Value Along

Dec 21, 2014

I just wanna have a very simple function that reads values from a text file row by row. The first value is passed along from the stringstream to my float data[] but after that it doesn't pass along anything. The strange part (for me at least) is that the stringstream contains the values it should contain, but they doesn't wanna end up in data[].

main.cpp
#include <fstream>
#include <iostream>
#include <string>
#include <sstream>

C/C++ :: Image Overlaid Five Consecutive Times On A Live Video

Nov 30, 2012

I am trying to overlay an image on a live video.I have used alpha blending method to overlay image on the video. On overlaying the image, it gets overlayed five times rather than one as expected.

Both frame data and the image data is taken as BYTE* for overlaying and displaying it.

The image used is a bitmap image.

The data (BYTE*) of both the video and the image is overlayed and the resultant is stored back in the variable of the video and den drawn on the picture control of vc++.

The video resolution is 640x480.

The image I m overlaying is 128x128.

The IDE used is visual studio professional.The code is developed using c++.

How do I overlay the bitmap image as a single image on the live video at a specific position.

C++ :: Estimate Springtime Count Of Deer In A Park For 10 Consecutive Years

Dec 2, 2013

Write a C++ program to estimate the springtime count of deer in a park for 10 consecutive years. The population of any given year depends on the previous year's population according to the following calculation:

• If the lowest winter temperature was less than 0 degrees, the deer population drops by 15%.
• If the lowest winter temperature was between 0 degrees F and 25 degrees F (inclusive), the deer population drops by 10%.
• If the lowest winter temperature was between 26 degrees F and 30 degrees F (inclusive), the deer population doesn’t change.
• If the lowest winter temperature was between 31 degrees F and 35 degrees F (inclusive), the deer population rises by 12%.
• If the lowest winter temperature was higher than 35 degrees F, the deer population rises by 14%.

I have started with:

#include <iostream>
#include <stdlib.h>
#include <string>
using namespace std;
int main() {

C++ :: Read Text File To Stringstream But Keep Line Feed

Jun 6, 2013

I build this function in my C++ code. I run the on a UNIX box, build HTML file to use in Windows.

In HTML file building code, I have only a string variable hold the contents of this text file (from unix) & add it into HTML file.

The issue is that when I view the HTML file on windows, it shows all the lines in the text file as one line. I think it lost the CRLF.

My question is when I add lines from text file (reading one line at a time) in UNIX, how do I maintain CRLF ( ) in the stringstream variable so that it will display on HTML in Windows properly, all the lines as it is in unix.

I am aware UNIX uses for line end.

string TextFileToString(string filename) {
string line;
stringstream dosString;
ifstream inFile;

C++ :: White Pixel Value Different From 255

Mar 12, 2014

I am working on image processing in C + + and opencv, I treat images in grayscale, ie the pixel values ​​it must be between 0 (black) to 255 (white).

Mat img; img = imread (file, -1);
for ( int i = 0; i < img. rows ; i ++) {
for ( int j = 0; j < img. cols ; j ++) {
val_pixel=img.at < double >(i,j);
printf( "%d ",val_pixel);
}
printf( "
");
}

when displaying the pixel value from two loop, I get values ​​to 0 and it is normal for propablement black areas, but for whites I find the value -2147483648. I don't understand why this value is not 255.Is there an explanation for this has value.

C++ :: Dynamic Memory (array Of Char) - Delete All White Spaces In Text File

General Purpose: Delete all "white spaces" in text file, until the read-in char is _not_ a whitespace (mark as start of text file).

Problem: Cannot seem to shift char's over properly. (I think my problem is the inner loop - however other code may lead to this problem - I do not know)

Code:

#include <fstream>
#include <iostream>
using namespace std;

bool trimWhiteSpace(fstream &file, char * charMemoryBlock) {
if (!file.is_open()) {
