C++ :: Program That Opens A File And Counts White Space Separated Words

May 17, 2013

Question is : Write a program that opens a file and counts the whitespace-separated words in that file.?

my answer is :

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

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.?

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++ :: Reading In Space Separated Versus Comma Separated Files

Jul 30, 2014

I just wrote a code that reads in a text file called "policies.txt" which looks like this:

Pol1 M N 20 100000 1 .04 99
Pol2 F S 30 100000 1 .05 99
Pol3 M S 72 750000 1 .03 99
Pol4 F N 45 1000000 1 .05 99

This works perfectly fine, but what if I want each element of the table to be separated by commas. For example:

Pol1,M,N,20,100000,1,.04,99
Pol2,F,S,30,100000,1,.05,99
Pol3,M,S,72,750000,1,.03,99
Pol4,F,N,45,1000000,1,.05,99

or better yet, what if I want it to not matter whether the columns are separated by commas or spaces? is there any way to do this? If there is no way to read in both comma-separated and space-separated elements simultaneously then I would prefer just comma, rather than the space separated which my code is able to read now. What modifications would I have to make to my code to make this work? This is my code to reference.

double ratesmn[86] = {
#include "MaleNonSmoker.txt"
- 1
};
double ratesms[86] = {
#include "MaleSmoker.txt"

[Code] ....

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();

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.

C++ :: Counts Number Of Words In A String That End With Ng

Dec 10, 2013

I am trying to write a code that counts the number of words in a string that end with ng.

I started with this but this just checks the end of the string. I need it to check everyword in the string and also count them up.

int main() {
string s;
cout << " enter string ";
getline(cin, s);
string end;
end = s.substr(s.length()-2, 2);
cout << end;
cout << endl;
return 0;

C++ :: Make Program That Counts Number Of Words / Lines And Vowels?

Mar 13, 2014

So I need to make a program that counts the number of words, lines, and vowels in a program. Punctuation and white spaces are not counted in any of the counts. I have this so far and the words, and lines work and are correct but I can't seem to get the vowel count to work.

#include <cmath>
#include <cstdlib>

C/C++ :: Splitting Words Into Space?

Mar 18, 2015

My code

#include<iostream>
#include<string>
using namespace std;
string strip(string message) { //removing elements that is not A-Z or a-z
string stripped;
for(int x = 0; x < message.length(); x++) {

[code]....

The output in my code shows like this:

[e]Encipher
[d]decipher
[x] Exit
Enter choice: e
Enter message to Encrypted:
i love you
Enter Key:
love

The encrypted message is: tzjzpmjy

Back to main menu? (y/n):

However , I want the output to display the spaces as the user's input.

ex. The encrypted message is: t zjzp mjy.

This is the same as i love you in the user's input.

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

Feb 8, 2014

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()) {

C++ :: Read From Semi-colon-separated File

Nov 9, 2013

I have a function reads from a file like this

file
foo;bar
foo;bar
foo;bar

function
void EntryList::loadfile(const char filefoo[]){
ifstreamin;

[Code] ....

I am in the middle of rewriting this program for at least the 4 time. and I have modified the file how I (humanly) think I should to this. I have had issues in the past, doing it this way. (still working on the other parts of the program so I cannot be too specific right now, but I know my results were unexpected ) So my question is does the function that I modified look correct for what I am trying to do? Am I off by one? I guess I am struggling with understanding how the original function is working. (step by step systematically.) hence my confusion about my modified function.

C/C++ :: Reading Data In A File Separated By Commas

Feb 14, 2015

I have a file with data in lines separated by commas and im trying to print out specific lines and specific parts of data from that line. I need to isolate lines where the first column of data reads '$CPGAR' and print out specific data columns.When I print out the strings I get random data and my strcmp to isolate lines isnt working? Im very new to this, heres a sample of my program:

while (!feof(gpsH)) {
char word1[10],word2[10],word3[10],word4[10],word5[10],word6[10],word7[10],
word8[10],word9[10],word10[10],word11[10],word12[10],word13[10];
char a[6] ="$CPGAR";
/* read data line */
fgets(gpsS,10,gpsH);

C :: Reading In Comma Separated Numbers From A Data File

Apr 18, 2013

I am attempting to read in a file that has 4128 sets of 21 numbers separated by commas and write it into an array. I now know that in order to use fseek, I have to make my array a character array, but I need my function to read in decimals (ex: 0.172635). I'm reading in

0.102598,0.000000,0.000000,0.000000,0.000000,0.307 793,0.000000,0.410391,0.102598,0.000000,0.102598,0 .102598,0.000000,0.000000,0.102598,0.102598,0.8207 83,0.000000,0.000000,0.000000,0.000000

and keep getting numbers like 48 49 50.

Code:

void CSread(char filename[100], char array[22], char array2[22], unsigned int arraysize)
{
char genename[32];
double temp = 0;

FILE *CSfile;
CSfile = fopen(filename, "r");

C++ :: Space File In String?

Mar 24, 2014

I have a problem, caught the last line of a file and do the division of the same variables in, date, time and value, but the file contains excess spaces in all lines and the date is coming with cuts, example 24/4/2014 appears 4/4/2014. How can I remove the space in the string without affecting the division of the line?

if (file) {
std::string line = getLastLine(file);
std::istringstream iss(line);
getline(iss, date, ' ');
getline(iss, time, ' ');
getline(iss, t); //variavel para temperatura em string
}
else {
std::cout << "error file

C++ :: Rename Failed With File Name Had Space / Hyphen After Unicode Support

I would like to know why the return value of "MoveFileExW" is false for file name consists 'space','hyphen' etc.(sometimes even without a Unicode character).for accepting 'space','hyphen' what type of conversion I would use [I.e.: Does the root cause of failure is due to CP_UTF8 type use].

//! Both are in same directory F: est_files
std::wstring unicode_input_original;
int unicode_input_length_original = 0
