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??
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; }
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)
this is the code I tried in my code block 10.05.....tried code for removing all white space from a line of a txt file. this is my code it runs but i cant get the result i need.
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.
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.
Write a program that opens a file and counts the whitespace-separated words in that file.?
My code that i wrote for this example is as follows...
#include <iostream> using namespace std; #include <iostream> #include <string> #include <fstream> int main() { string filename = "Question 1.cpp"; // File name goes in here
int main() { string filename = "Question 1.cpp"; // File name goes in here
[Code] ....
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.?
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[].
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.
Develop a function that finds the greatest difference between two consecutive elements stored in an array. Develop a 9 element array of doubles to test your code. Print to the screen which two numbers have the greatest difference as well as the value of the difference. Finally include an overloaded version of the function that will work if the array is composed of integers. Include your code used to test this function.
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() { int year; int pop1;
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 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.
I 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:
(I switched back to the FF pipeline temporarily, in my other projects I use shaders.)
as i am doing an encryption program on a playfair cipher. 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?
im 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;
[Code].....
i click run in xcode, but something goes wrong. the build succeeds but in the output screen it says (11db)
I 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] == ' ')
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()) {
I used pointer(or is it not?) to make it one part only alphabets and the other one digits. The coding, calculate_charges.c and the open file, customer.txt are attached at the end of the post.
Code:
#include <stdio.h> #include <string.h> #define SIZE 3 void trimback(char input[], int strnameindex); void trimfrnt(char input[], int strnameindex); }
