C++ :: Searching Through Entire String Looking For Spaces / Punctuation
Dec 11, 2014
I 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>
[Code] ....
Output:
if(str_word == " ")
//or
if(str_word == ' ')
It does nothing to change it. I am completely baffled.

Write a program that reads a string of characters including punctuation and writes what was read but with the punctuation removed.
This is how i did it:
string x("#punctuation!?=");
cout << x << endl;
for(unsigned i = 0; i < x.size(); ++i) {
if(ispunct(x[i]))
x[i] = ' ';
cout << x << endl;
I am just not sure if thats how they want you to do it because it doesn't remove the punctuations it just replaces them with a space.

I 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.

How can I extract the number out of the string:
string my_sting = "item code = 9";
I want to get the '9' out of the string and store it in a separate int variable. I tried using sstream library and was having trouble.

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?
example: hello world

I want to input a string in C with white spaces in between. I have tried %[^/n]*c, and fgets, but both do not work.

I have 80,675 Files, 8,213 SubFolders.
I would like to search each file for a string, which will be last name.
Matches string, outputs path/filename, either to screen or a output file.
I have done this to a single file but never to multiple files and folders.

I'm trying to find a < character in a document, get it's position. Then find > and get it's position. Then i want to delete all things between that but runtime is terminating my process so i don't know what to do.
The code:

#include <conio.h>
#include <stdio.h>

So i have this program that's supposed to count all the characters including the spaces without using strlen but it only counts the number of the first word's characters and it does not include the rest of the words after the first space. how do i include spaces in the count?
#include <iostream>
#include <conio.h>
#include <stdio.h>

New to C++ lambda, got two question in regards of searching for strings within a vector struct.
Minimalistic example:
Code:
struct singleFile {
std::string filename;
};
std::vector<singleFile>myStorage;
myStorage.push_back(singleFile());
[Code] ....
1) why does found always return 0 eventhough the filename exists?
2) I don't know how to pass an actual search string instead of the hardcoded approach as above with filename =="

I want to make a program that receives the number of lines and collumns of a matrix, a matrix of char, the number of pairs of coordinates and the coordinates. the program has to return the char (or chars) that are on those coordinates on the matrix.
Example:
receives
2 3 ABC DEF 2 1 1 1 2
returns
AB
this is how i tried to solve this problem:
Code:
#include
#define MAX 1000
int main() {
int nlin, ncol;
char mat[MAX][MAX];
int x[MAX], y[MAX];
int ncoords;
int l, c, n;
/* receiving variables and storing matrix.*/
[Code] .....
For some reason that i can't seem to find, this solution is not right.

Write a function to read and display the contents of names and marks. You then ask the user for a name and using the linear search return the index to the user. If -1 is returned then the name is not in the file. Otherwise write out the name and mark for that student.
Next, sort the arrays, write them out and then ask the user for a name to search for. This time use the binarySearch to return -1 or an index. Display the student's name and mark if found.
void getNames(ifstream& inStream, string names[], int marks[], int numElts);
int linearSearch(const string names[], int numElts,string who);
int binarySearch(const string names[], int numElts,string who);
void selectionSort(string names[], int marks[],int numElts);
void displayData(const string names[], const int marks[], int numElts);
[Code] ....
Now I have worked up some stuff in parts but I am so lost and confused with these specific requirements: Previous questions asked me to sort out a linear search, a binary search and
LINEAR SEARCH:
int searchList(int list[], int numElems, int value) {
int index = 0; // Used as a subscript to search array
int position = -1; // To record position of search value
bool found = false; // Flag to indicate if value was found
[Code] ....

The program then asks the user for a search string, which may contain white space. The program should search the file for every occurrence of the search string. When the string is found, the line that contains it should be displayed in the following format
nnnnn:Line Contents
That is the line number of the line, 5 columns wide, right justified, followed by a colon, followed by the contents of the line.
And this is what I've got so far:
Code:
#include<iostream>
#include<fstream>
#include<string>
#include<iomanip>
using namespace std;
int main(int argc, char *argv[]) {
ifstream inFile;
string fileName,
[code]....
But this doesn't work. It prints everything in the file, not just the lines where the string is found.

I want to separate this binary string every 4 characters..I am trying to get a better understanding of how variables are stored in memory and I am looking at their binary address for a pattern..I see a pattern for the last 4 bits
#include <iostream>
#include <bitset>
int main() {
using namespace std;
int x[100];

I am having some trouble tokenizing some strings in C. I am trying to take in a string dynamically and spit print it to the console tokenized using the spaces as delimiters. I have tried using frets() and scant() as well as playing around with pointer values to no avail.
#include <stdio.h>
#include <unistd.h>
#include<string.h>
#include <stdlib.h>
#define MAX_LINE 80

My program is a dictionary vector with a cin at the end that will read your input and check if it's in the dictionary.
#include "std_lib_facilities_3.h"
#include <algorithm>
#include <string>
#include <iostream>
string translate_to_lower(string s){
transform(s.begi[/code]n(), s[/code].end(), s.begin(), (int (*)(int)) tolower);
[Code] ...
How do I make the program accept inputs such as "hello?", "hello!", and "hello,"?

Now, I have an assignment in which I am to accept arguments from the command line and copy them into a cstring and display said cstring unmolested. Then I should store it into another cstring but ignore all punctuation, spaces and capital letters. Like this:
./a5 Marge lets Norah see Sharon's telegram
As is: Marge lets Norah see Sharon's telegram
---->: margeletsnorahseesharonstelegram
<----: margeletsnorahseesharonstelegram
Sequence entered is a palindrome
=======================================================
Finally I am to chaeck to see if it is a palindrome. Most of it works and if no spaces are entered nor punctuation it works. However, punctuation causes it to malfunction.
char *FormSeqProc (int argc, char *argv[], char seqAsIs[]) {
int len = 0,
n = 0;
for (int p = 1; p < argc; ++p) {
len += strlen(argv[p]);
[Code] ....

The general design of my app work-flow:
My application is processing a large amount of data (approx. 50 - 100 GB of txt data). given the machine regular user usually has, my app is writing some tmp data into a local tmp directory. and this is working just fine until users get comfortable with my software and start changing that content of local tmp dir (while the program is running). which does not give any problems like crashing a program if handled at the right time but produces wrong results in the end. now this is not my problem but i would still like to somehow restrict users from even peeking into the tmp dir. I am just tired of getting emails saying my software is cr.... (maybe it is but i don't think it is because of that)
So is it possible to somehow encrypt the entire dir so that only the program has access to it . it would be even better if the dir could look as some encrypted index file so that when user sees the warning :
"tmp" may be a binary file. See it anyway?

Okay so I've declared an array like this.
Foo *Blocks[100][100][10000] = {0};
And as far as my understanding goes This creates an array with every member set to NULL.
And then later on in my code some of these get given values using:
Blocks[a][b][c] = new Foo;
And then when I want to unload I would think that I could just go
Blocks = {0};
But obviously this doesn't work.
So I was wondering if there was a way of doing This, with out creating a loop and changing every one to NULL manually.

If I have a char array that that looks like
char array[] = {'a', 'b', 'c'};
How can I check user input against all of these values at once?

I just want my program to run continuously until someone enters 0 to exit it. I tried doing while(x=1) and looping my entire block of code. Also there is a switch one is a for one is a while loop both doing the same function. I have basic error checking and whatnot.
/*This is a program that gets a user to input a starting and ending value.
The code then prints the number ie 1 and 5 would be (1,2,3,4,5) and all the squares and cubes.
There is a case statement asking weather you want to run it as a for or as a while loop.
The choices are case sensitive.
*/
#include <stdio.h>
#include <stdlib.h>
#include <math.h>//allows for power and cube function
int x;
int main(){

I would like to store the entire content of a file in a single c-string variable or in a standard string class variable. Is there a function that will do this for me? I am familiar with functions that get one character or one line at a time but I don't think I've encountered a function that gets the entire file. Does this function keep or disregard the end-of-line character? If no such function exists, I would write my own function to create and return such a variable.

I am working on a drink machine simulation. I have a text file that holds the prices, names and inventory. My problem is It won't let me set my prices at 1.00 or higher. Ex: I set the price to 1.50 in the text file then when it reads the info and stores the price it only stores .50 instead of 1.50.
my code:
#include <iostream>
#include <string>
#include <fstream>
