So I need to read a file that has this input and need to delete the comma and semicolon in the string but idk how to ignore the comma and semicolon:
ex of input file: A firstname, lastname; 13
I did this:
Code:
i = 0;
fscanf (fData, "%c", &grade);
fgets(space,2,fData);
do{
fgets(name,50,fpData);
i++;
}while(temp[0] == ';');
temp[i] = temp[i - 1];
fscanf (fData, "%d", &age);
I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main() {
string str = "3 J JD,K";
stringstream ss(str);
[Code] ....
Output of the code is
3 J JD
k
but I want
3
J
JD
K
Also after I split the string is there any way to put the split string into individual string variables.
I have a string that receives a value, with comma eg 11,222
How do I convert a string to comma point?
I'm trying to convert the string to float, however because of the comma does not handle values before the comma
float to_float(const std::string& str)
{
std::istringstream is(str) ;
float result;

The below code is taken from open source filezilla project
(FileZilla_3.7.3_srcfilezilla-3.7.3srcinterfacebookmarks_dialog.cpp)
Code:
#include <filezilla.h>
#include "bookmarks_dialog.h"
#include "sitemanager.h"
#include "ipcmutex.h"
#include "themeprovider.h"
#include "xmlfunctions.h"
BEGIN_EVENT_TABLE(CNewBookmarkDialog, wxDialogEx)
EVT_BUTTON(XRCID("wxID_OK"), CNewBookmarkDialog::OnOK)
EVT_BUTTON(XRCID("ID_BROWSE"), CNewBookmarkDialog::OnBrowse)
END_EVENT_TABLE()
I'm unable to understand what are these lines after the #include. They don't end in semicolons. Looks very much like function calls.
Are BEGIN_EVENT_TABLE, EVT_BUTTON and END_EVENT_TABLE function calls? Function calls should end with semicolons right?
"Type a function that take in a string containing numbers and others characters and print on stdout all the numbers contained into the string, where for number is mean every maximal numerical sequence, of numbers not separed by spaces. Numbers printed on exit must be separated by commas. For example, if i put in the function the string "paje27hg78 2k f562" my function must print:
27, 78, 2, 562 "

Delete last four characters.
I want do delete all occurrences of a char in a given string, but I really don't see my error in the code. Here is how I did it:
Code:
char *input = "example_string";
int len = strlen(input);
char *new_line[len];
char bad = 'e'; //the one to delete
int i;
int j = 0;

I get segmentation or bus errors.. And I also don#t understand the warning I get. new_line is an array of chars, and I am trying to assign to it a certain char.
I have to manage a Clinic. I need to delete a booking (for example, if John said he's coming on March 22nd at 15:30 but then he say he's not going to come, I have to delete that booking so another person can use it).
idSearched: the id of the person that is not going to come. I have a lot of specialties and each one has a list. So I ask for the speciality to delete the node (the node contains John's booking). If I don't find it, I return (-1). searchSpecByID return a pointer to the list where the speciality is. So head will point to the first node of the list. In nodeToDelete I have the node I want to delete.
The program detects OK when is the first in the list and when not, but it doesn't delete the node.
Code:
typedef struct bookingList{
tSpecialty specialty;
struct nodo* intro;
} tList;

I have tried with some logic for removing comma operator in test.ini file but its not working how to remove comma and get output. For example:
Input
inside test.ini file the name is in format,
ajs,18.0,15.0
expected output
ajs 18.0 15.0
but I am getting,
ats,18.0,25.0 2686760 4200912
Code:
#include <stdio.h>
#include <stdlib.h>
int main()
{
FILE *fp;
char strConfName[25] ;
float a,b;

I am trying to write a way to properly format numbers by adding "," to numbers. Ex:
1000000 -> 1,000,000
30000000000000 -> 30,000,000,000,000
In the usual case, its an easy problem. But it gets tricky in my case, since I am working with numbers up to 30 digits, unable to store them in any int, long, long long. Due to this obstacle, the user inputs a number and each digit is stored in my array individually.
I need these commas to print as I am cout the array. This means I only have array length to work with.
I want to use modulus, but I'm not sure how this would work. I have:
void prArray(int Array[], const int arrSize) {
int mod = arrSize % 3;
int remainingSize = arraySize;
int counter = 0;
for(int i=0; i <= arrSize; i++){
remainingSize--;
[Code] ....
Which outputs the first digits correctly, but leaves 4 digits at the end:
235423452345 -> 23,542,345,2345
Likewise
2354234523450 -> 235,423,452,3450
I'm trying to read names separated by a comma using array.
For example, the expected input would look like the following:
Juila,Francisco
Adams,Wong
I know you can use getline function and set the delimiter to comma. So like ....
getline(cin, lastName, ','); getline(cin, firstName);
But the program only read the last name and ignore the firstname.
TinyGPS::TinyGPS()
: _time(GPS_INVALID_TIME)
, _date(GPS_INVALID_DATE)
, _latitude(GPS_INVALID_ANGLE)
[code]....
I am wondering about the constructor. I see there appears to be nothing inside of TinyGPS::TinyGPS() as far as parameters go and that that declaration is followed by a ":". First I'm wondering as to the meaning of the colon. As well with the variables defined after the ":" I see some "(0)" and I am wondering as well to the exact meaning of the "(0)". Are those variables being defined as parameters separated by ","?
I am having a hard time trying to get data into an array of objects. The data file has 3235 lines, state, fips code, and county. The state and fips code are getting stored correctly but some countys have 2 or more words in them (now noticing the "and" is missing from one of them.
sample of the file:

I'm trying to enter an 'x' and 'y' coordinate on only one line separated by a comma. But I keep getting a syntax error. Here are the lines of code I'm using. This has to be simple. What am I doing wrong with this code?

cout<< "use a comma to separate them. " <<endl<<endl;
cin>> "You entered: " >>x1>>",">> y1 >>"for the first point" >>endl;
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

I have been trying to read a comma separated .txt file into an array and print it to console in C++. The txt file consists of two columns of double type data. For some reason the program runs, but gives blank output in the console. I want to know if I am doing something wrong. So far this is what I have:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
int i=0;
double x[10];
double y[10];
string line;

I'm trying to get my program to read a series of comma delimited values from a file into a vector. However, I am unsure how to actually go about doing this. I've posted my best guess below but it's really just a stab in the dark and I always receive a compiler error.
Code:
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
using namespace std;
vector <string> v_input;
int main() {
ofstream fout ("Insert File Path Here.txt");
fout << "4, 8, 15, 16, 23, 42";

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.

I am beginner with C++ and I want to know. When do I use new and delete keywords? And what can I use them to do? Only thing I know about the new keyword and delete is that you can do this:
Code:
int Size = 5;
int *ptr = new int(Size);
cout << *ptr << endl;
delete ptr; And more . . .
But when do you use this keywords? I am just curios about them and want to now if them can be really effective to use.

How would I delete a row in a datagridview (and in the database) if the datagridview control does not show the primary key? ie the SELECT statement we used to load the DataGridView does not include the primary key column (since it is not relevant to the user)
