when i take input as:

10,4,74,61,8,37,2,35

i get runtime error.but if i remove 8 from input and cin>>n from code the code is working perfect . How can i take n also as input? example link "https://ideone.com/hr96ef"

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

int main() {
int n;
cin>>n;
std::string input_str;
std::vector<int> vect;

std::getline( std::cin, input_str );

std::stringstream ss(input_str);

 int i;

while (ss >> i)
{
  vect.push_back(i);

  if (ss.peek() == ',')
  ss.ignore();
}
cout<<vect[3];
return 0;
}

hello

After the call to `std::getline` look at the contents of `input_str` to make sure it's what you expect. – Pete Becker Aug 11 '17 at 15:55
I update the question,added link to example code please check – hello Aug 11 '17 at 15:58
use std::istringstream ss( input_str ); instead – arturx64 Aug 11 '17 at 16:35
thank you cin.ignore(); solved the problem – hello Aug 11 '17 at 18:05
