how I can read until eoln in c++?

[Giorgi]

please help to read integer numbers until eoln.

in pascal a do it so:

Code: Select all

var k:integer;
 begin
  while not eoln do 
   begin
    read(k);
    . 
    .
    .
   end;
 end.

You can do it with this code:

Code: Select all

int k; char c;
while (scanf("%d%c", &k, &c) == 2 && c != '\n') { ... }

(Of course, this assumes that there are no trailing spaces at the end of line.)

thank you

You can skip any trailing spaces by "%*[ ]".

........scanf("%d%*[ ]", &a);
........scanf("%c", &c);

You can simple get line and then use std::istringstream

[Zyaad Jaunnoo]

Code: Select all

#include <iostream>
#include <string>
#include <sstream>

using namespace std;

int main()
{
	string line;
	getline(cin, line);

	stringstream stream(line);

	int k;
	while (stream >> k)
	{
		cout << k << endl;
	}

	return 0;
}
