C++ :: Tokenizing A String Using Delimiter And Show Output Using STL
Mar 3, 2014
Write one program that receive a string, tokenize it by ' ' delimiter and show the output, using STL
So, I write:
#include <stack>
#include <iostream>
#include <vector>
#include <string>
using std::stack;
using std::cout;
[Code] .....
And...
Type any string and I'll say its proprieties:
> A B C
String length: 5
Words number: 3
Word 1: (split(input)[0])
A
Word 2: (split(input)[1])
B C
Word 3: (split(input)[2])
C

What am I doing wrong?

PWCHAR Return[10];
int I=0,s=0;

How delimiter work. I need write a function that splits the string by delimiter. Function header is:
vector<string> split(stirng target, string delimiter);
for example, the code inside main calling your function
vector<string> v = split("hiAAAmyAAAnameAAAis", "AAA");
and v should come out as hi my name is
So is it something like
vector<string> split(string target, string delimiter) {
vector<string> word;
string s = "hiAAAmyAAAnameAAAis";
string delimiter = "AAA";

How do I use a string in place of a character in the function getline?
For example,
getline(infile,lines,'}');
This works fine, but I want the delimiter of } to be "};", but I can't do this as it only takes in characters, not strings.
I want:
getline(infile,lines,"};");
Any way to get around this?

I Need to write a function using C wherein I should do the following:
(i) The function will receive a string in a character pointer
(ii) This string will adhere to the following structure:
"Kentucky+New York+Arizona+Nevada"
The number of states can differ from 4 to 50
The delimiter between States can differ from '+' to ',', hence I would like to pass the delimiter to the function.
(iii) This string should then be sorted alphabetically from left to right.
The above example would then become: "Arizona+Kentucky+Nevada+New York"
(iv) This string needs to be returned from the function using a character pointer.

I would like to know if there's a way to show at least two numbers in the output instead of just one. For example: instead of showing 4 it shows 04. Its for a console application.

I need to know if it is possible to show the maximum length that is defined a string. I explained it with a example
void charLong(char *a){
cout <<"a defined max long = "<<a-><FUNCTION>;
} int main() {
char str[40];
charLong(&str);
return 0;
}
That the result was : a defined max long = 40.
I know that exist strlen() but this show only the length that is used, I need the definition length. is it possible?

write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use a character array to store the string.) Does this follow the criteria? This program is very similar to one I found on these forums but I have one problem, it outputs everything backwards! EX: dogs will output to SGOD. What I need to do to make it output correctly, I think it may have to do with getline?
#include <iostream>
#include <cctype>
#include <cstring>
using namespace std;
int main() {
char let[100];
cout << "Enter what you would like to be UPPERCASE: ";
[Code] ....

Is it possible to fgets() the string (or word) only after a delimiter? I yes then how?
Example: Code: printer, scanner, machine
Also, how can I sscanf() a string with an indefinite number of sizes and assign it to only one variable?
Example:
Code:
str = "I Love C programming 9000";
sscanf(str, "%s %d", strvar, intvar);

I have attached the file that I need to read into a data structure. In the example I am just printing it to the screen. This following code has worked for me before, but now isn't. I have tried in visual studios, and on unix, and neither are running it. I ultimately need it to run on unix.
Example file:
word
book
programming
Here is my function to read in the file.
ifstream file;
string line;
file.open("words.txt");
if(file.is_open()){
while(!file.eof()){
getline(file, line);
cout << line <<endl;
}
}
file.close();

I want to read a binary file using as line separator "ff77" in order to parse further each line one by one with some regex since the file is big. I have a small ruby code shown below, but I'm new in C++, and I don't know how to replicate in C++ what this ruby code does.
Code:
#!/usr/bin/env ruby
BEGIN{ $/="xffx77" } # Line separator = FF77
File.open(ARGV[0],"rb") # Open in binary mode

I am trying to read a file use the data line by line to create into an object. The current file I have is like this and the code reading the file will be found below.
1223 Fake1 Name1 60 70 80 24 89 add1 Male
1224 Fake2 Name2 61 70 81 80 24 add2 Male
1225 Fake3 Name3 63 70 82 80 89 add3 Male
1226 Fake4 Name4 63 70 83 80 88 add4 Male
The problem I am having is that I need to put delimiters in the file so that a person can have more than one name and also the address can now hold multiple strings until the delimiter.
I would like to change my file to this;
1223 : Fake1 Name1 : 60 : 70 : 80 : 24 :89 : This will be address1 : Male
1224 : Fake2 Name2 : 61 : 70 : 81 : 80 :24 : This will be address2 : Male
1225 : Fake3 Name3 : 63 : 70 : 82 : 80 :89 : This will be address3 : Male
1226 : Fake4 Name4 : 63 : 70 : 83 : 80 :88 : This will be address4 : Male
How can I update the code below so that it can use the delimiters to create an object?
void loadFile(Person people[], int* i) {
ifstream infile("people2.txt");
if ( !infile.is_open()) {
// The file could not be opened
cout << "Error";

I want to process data (using fstream) and print out the progress. This doesn't work with cout <<, only with puts, but this causes a line-break but I want a progress bar like this : [=====================].
I've already searched for an hour in the reference and with google and I dont manage to put a string without a linebreak:
while (ein.good()) // loop while extraction from file is possible
{
c = ein.get(); // get character from file
if (ein.good()){
[Code]....
how to do it without the linebreaks..

I am writing a small editor for RSL coding, and ive got an external program "3Delight" to compile the code.
Now i want the output from that exe to be captured in a string once the compilation is comlete, but all of the methods ive found online dont seem to work for me. Ive tried using _popen which works if i run a normal command like "dir", but not with the exe.
This is the function ive been using that works with the normal commands
std::string exec(const char* cmd) {
FILE* pipe = _popen(cmd, "r");
if (!pipe) return "ERROR";
char buffer[128];
std::string result = "";
[Code] .....
and this is how i was calling it, but it just returned an empty string, even though the exe printed "Compilation successful"
exec("""%DELIGHT%/bin/shaderdl" "E:/RenderManShaders/TestArea/Source/basicDiffuse.sl"")

string codes[] = {

I'm reading in a string from the command line into a char array followed by a series of ints which are read into an int array.
The command line
Code: lab3 word word word 0 0 2 3 results in the following output:
Code: Word: .N=▒
Number of Words: 0
Word: .N=▒word word word
Number of Words: 3
Num: 0
Num: 0
Num: 2
Num: 3
Here is the source code:
int main(int argc, char *argv[]){
if(argc < 2){
//command line must have at least three arguments (one
//char, one integer)
printf("Error: invalid number of arguments

Where is the .N=▒ coming from?

So basically here I have a menu in my C program and if I were to select option 2, I would enter a string up to 30 characters and it would output each block of 16 bytes should be shown which contains a character in the requested string. However, when I compile and run the program and search for the string, nothing happens. what I may be doing wrong?
Code:
else if (select == 2){
printf("Enter a string of up to 30 characters: ");
scanf("%s", &userstr);
//Compares both user's string and file string
for (i = 0; i < size; i++){
if (strcmp (buffer, userstr) !=0){
