I am now stuck on a problem on decryption.If my string is helloworld (without a space), it will decrypt normally.However , if my string has a space in between it. Let`s say Hello World, it will not decrypt normally.How do i take into account the space that is in between hello & world?

C++ :: Program That Eliminates White Spaces
May 8, 2013im trying to write a program for class that when it reads it, it corrects all the spacing and capitalization. so for example, the phrase "the quick bRown fox jumped over the lazy dog" would be converted by the program to "The quick brown fox jumped over the lazy dog"
here is my code:
#include <iostream>
#include <string>
using namespace std;

i click run in xcode, but something goes wrong. the build succeeds but in the output screen it says (11db)
C++ :: Palindrome - Program Goes Into Infinite Loop Whenever Word With White Spaces Added
Feb 9, 2013I have an assignment where i have to make a palindrome program. As you can see i have already done the basic palindrome prog, however i am now stuck since the program goes into a infinite loop whenever a word with whitespaces is added.
I have also tried searching for methods online however they do not seem to work for me...
void CPali::check() {
length = strlen(palin);
for (int i = 0, p = length-1; p>i; i++, p--) {
if (palin[i] == ' ')

C++ :: Dynamic Memory (array Of Char) - Delete All White Spaces In Text File
Feb 8, 2014General 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()) {

C++ :: Input 150 Digit Integers From 0 To 9 And Not Put Spaces Between Them
Jul 26, 2014So I want to do the following, I want to input 150 1 digit integers, from 0-9 and I don't want to put spaces between them while inputing, like if I input a 150 digit integer, the compiler should take it as 150 1 digit integers. I'm not sure how to accomplish that.
int a[150];
for(int i=0;i<150;i++)
cin>>a[i];
If I try to do it with above code, the compiler needs a space to know when the value of i is incremented. But I want to avoid spaces for my task.
C# :: Finding A String Starting With Spaces Within Another String
Sep 8, 2014I need to find a string with leading spaces like " target sting" inside another sting.
And I need to find something like "target sting" inside another sting.
I used .IndexOf() but noticed it ignores leading spaces.
So then I went with .Substring() but that doesn't seem like that's the best solution either.
C++ :: Get Int Out Of String With Spaces
Feb 28, 2014How can I extract the number out of the string:

C++ :: Searching Through Entire String Looking For Spaces / Punctuation
Dec 11, 2014I have it searching through the entire string letter by letter, looking for spaces, punctuation, etc... yet it still is continuing on with the space.
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <stdio.h>
#include <cctype>
#include <algorithm>

Output:
if(str_word == " ")
//or
if(str_word == ' ')
It does nothing to change it. I am completely baffled.

C++ :: White Pixel Value Different From 255
Mar 12, 2014I 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++ :: Textures White In OpenGL
Nov 17, 2013I don't know why, but textures in OpenGL are white. One day, I must've change something, and now my textures wont load properly. I tried rewriting my code that loads things multiple times, my textures still are white. Here is my code:

C++ :: Stringstream Consecutive White Space
Oct 1, 2013So 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??

C/C++ :: Taking String As Input And Making It As Whole Array (string Literal)

Mar 14, 2015I'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)

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},

C/C++ :: Comparing Input String To Type String Vector
May 29, 2014I wrote a program that reads a list from a file and stores it in a string type vector. Now, I want the user to input a word so that the program can search the vector to see if that word already exists. I have used every possible way of reading input from the console and storing it in order to compare with the vector but it never results in a match. When I print the input string and the vector string they are exactly the same thing (or at least print to the console as if they were). I've tried using getline; using cin direct to a string var; using cin to a char array and then casting to string using string str(arr); I even added a newline at the end just in case and STILL I cannot get a match.
vector <string> currentSet; //read a list in from a file and has 9 items in it
cin.ignore();
string line;
getline(cin, line);
if(line == vector[0]){//if printed to console line is HEAT and vector[0] is HEAT
cout<<"match"<<endl;
}
C/C++ :: Input Lowercase String / Output Uppercase String
Dec 3, 2014write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use a character array to store the string.) Does this follow the criteria? This program is very similar to one I found on these forums but I have one problem, it outputs everything backwards! EX: dogs will output to SGOD. What I need to do to make it output correctly, I think it may have to do with getline?
#include <iostream>
#include <cctype>
#include <cstring>
using namespace std;
int main() {
char let[100];

C++ :: Ifstream Insertion With White Space Delimited Data
Jun 21, 2013I'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.

C :: Comparing Of Characters In Given String From Input String?
Feb 7, 2013I am stuck in this program, Be given a string of chars, where each single char belongs to the following alphabet: a..zA..Z0..9 (So, in the string there are only lowercases, uppercases and digits. No blank, no comma, ...). For every char of the given alphabet, count how many times in the string
1-- the char belong to a sequence of identical chars whose length is at least three (i.e.: in the string cc74uyrpfccc348fhsjcccc3848djccccc484jd for three times the character 'c' satisfies this condition)

C++ :: Input String Text Into String Array
Jun 26, 2014/*assume array is already initialized and declared and is of array type string.*/

cout<<"Enter new value "<<endl;

cout<<array[i][j]<<endl;
I'm having lots of trouble with storing a cin string text into a string array. It just seem that after I cin newvalue, the program crashes. Is this way of storing it considered illegal? I'm just a beginner with 5 months of coding experience in C++.
