Breaking the String into Tokens

[menewbie]

Hi Guys !

I'm get input from the user and then storing it in "s " and then trying make tokens, but it is not working, and after making tokens i'm counting them.

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

int main(){

	string s;
	cout<<"Enter Text: " <<endl;
	cin>>s;
        cout<<"Entered Text is: " << s <<endl;

	istringstream iss(s);
	int count = 0;

	while(iss){
		string sub;
		iss>>sub;
		cout <<"token " << count + 1 << ": " <<sub <<endl;
		count = count +  1;
        }
	
	cout<<"Number of tokens "<<count -1 << endl;
}

[b]Output[/b]

Enter text:
Entered Text is: This is String
token 1: This
token 2:
Number of tokens: 1

The problem is that it ignores the rest of string which is "is string" and only consider first word. and also trying to store the first two words in two different variables

Thanks in advance

Sincere Regards,

cin>>s;
This will only read one word. Use std::getline to read the whole word.
getline(cin, s);

Thanks Peter

and how to remove the extra token it is generating

Output

Enter text:
Entered Text is: This is String
token 1: This
token 2: is
token 3: String
token 4:

and store This and is into two different variables?

Kind Regards,

Ewa

You could store the values in a vector (or some other container if you prefer).

Okay Thanks for helping i'll work on that one and may need your help to correct it. i'll try to put it into vectors

and how to remove the extra token it is generating

You should read it like so:

		string sub;
		while(iss>>sub){
				cout <<"token " << count + 1 << ": " <<sub <<endl;
		count = count +  1;
        }

Hi Guys !

Thanks to Peter and coder helping, your help was very fruitful, i wouldn't make it without your help

And here is my final code if anyone have the same problem

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

int main(){

	string s; 			
	string sa[20];		
	cout<<"Enter Text: " <<endl;
	getline(cin,s);		
	
	cout<<"Entered Text is: " << s <<endl;

	istringstream iss(s);
	int count = 0;

	while(iss){
		string sub;
		iss>>sub;
		if(sub == "")  // breaking input string into tokens
			break;
			cout <<"token " << count << ": " <<sub <<endl;
			sa[count]= sub;  // putting into array
			count = count +  1;  
				
        }
	
	
	cout<<"Number of tokens "<<count << endl<<endl; 
	for(int i = 0; i<2; i++){ // print first and 2nd number tokens
		cout<< i + 1 <<" Element of user input is: "<<sa[i]<<endl;
	}
	
	return 0;
}

Ewa
