Retrive multiple character in a string

[picass0]

my string contain "hello baby" and i wanted to find the position of the character 'l' which falls in pos 2 and 3. Using string.find("l") return me the position of first "l" found. How can i do a loop to find the position of my next character 'l' in the string?

Use 1st variant in some kind of loop.

The documentation is all you really need, but an example always helps. :)

#include <iostream>
#include <string>
#include <vector>

int main()
{
  typedef std::vector<std::string::size_type> IndexList;

  std::string s = "hello baby";
  IndexList indexes;
  std::string::size_type index = 0;

  while ((index = s.find('l', index)) != std::string::npos) {
    indexes.push_back(index);
    ++index;
  }

  for (IndexList::const_iterator i = indexes.begin(); i != indexes.end(); ++i)
    std::cout << *i << '\n';
}
