This article teaches you how to parse split delimited string in C++. This is one of the most handful function you can use for delimited string like CSV – comma separated value.

#include <string>
#include <vector>
#include <functional>
#include <iostream>
using namespace std;
void split(const string& s, char c,
           vector<string>& v) {
   string::size_type i = 0;
   string::size_type j = s.find(c);
   while (j != string::npos) {
      v.push_back(s.substr(i, j-i));
      i = ++j;
      j = s.find(c, j);
      if (j == string::npos)
         v.push_back(s.substr(i, s.length( )));
   }
}
int main( ) {
   vector<string> v;
   string s = "Account Name|Address 1|Address 2|City";
   split(s, '|', v);
   for (int i = 0; i < v.size( ); ++i) {
      cout << v[i] << '\n';
   }
}
