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.?

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
[Code] ....
Is this correct or am i missing something?

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 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"

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 <iostream>
#include <fstream>
#include <cmath>
#include <cstdlib>
#include <string>

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();

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},
};

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.

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;
}

I need to write a c program that opens a file in note pad. The first line is the number 5, for how many rows of binary strings are to follow. Each line contains a string representing a binary number (with a maximum of 32 binary digits) The program is supposed to read this file, and convert each binary number to base 10.
This is the binary code to test:
5
0110010101010100100101
10110
10000

I need to create a program that asks the user for the filename, then counts the number of occurrence of each letter in that file.
Ex. if the file contains
Absacsac
asdasda
Output will be
a = 6
b = 1
c = 2
.
.
.
z = 0
This has been my program so far:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
#include <cstdlib>
void countingFunction(string sentence) {

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.

I've been searching for a long time to find a way to make a cpp program that opens google chrome and goes to a specified url and nothing is working. This is the current code i'm using but its not working because no one really specifies the includes & dlls necessary for execution or if they do they compile with errors....
This is the basic code i've been using. Apparently, ShellExecute is the preferred method to do it. Its not really turning out to be my favorite right now...
int main(){

I wrote this code to search words in the file and display if the program found the word or not. when i write the words in the file on the same line (without the endl) like this :
w_toFile << "gilbert";
w_toFile << "lara";
w_toFile << "rana";
i can search any word.
but when i write them with the endl, the program can find only the first word. what can i do to make the program find any word even if they are each on a line?
here is the full code:
#include <iostream>
#include <windows.h>
#include <fstream>
#include <string>
using namespace std;
int main (void) {
string wordsearch;

The below program is supposed to display the contents of all files listed in the command line. When I try to run the program I get the fatal error "Debug Assertion Failed" Expression: file != NULL. I've done some researching on the matter and I gather it might be because I don't have any files listed in the command line?
How to enter files in the command line! I opened the Command Window in Windows XP and tried typing in "C> argc" and "% argc" (argc being the name of the file containing the below program) without any luck.
Code:
#include <stdio.h>
#include <stdlib.h>
int main (int argc, char * argv[]) {
int ch; // int to hold EOF
int count;
FILE *fp;
for(count = 1; count <= argc; count++) // agrc loop

Okay, so I think I have just passed the intermediate line in my skill of c++ and my question is how do I make a program that opens unknown files extensions. for example like .plr. Because I see a bunch of files for game modifications like that, that was a good reason I started c++ too.

I am trying to make a simple program, I would like it to be able to do the following, Write a program that opens two text files (input1.txt and input2.txt) for input .The program should write the followings in the two files. input1.txt:
This is the first line in input1.txt.
This is the second line in input1.txt.
This is the third line in input1.txt.
This is the fourth line in input1.txt.
input2.txt:
This is the first line in input2.txt.
This is the second line in input2.txt.
This is the third line in input2.txt.
What would be the best way to go about doing this? I wrote the program below, but I don't think that it works.
#include <iostream>
#include <fstream>
#include <string>
int main()
{
using namespace std;
string input1;

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] == ' ')
