How to convert a single char to a null-terminated const char*

I want to loop through a string of characters pull each one out and each one has to be of type const char* so I can pass it to a function. Here's an example.

string thestring = "abc123";

for(int i = 0; i < thestring.length(); i++){
    const char* theval = thestring[i]; // somehow convert this must be type const char*
    string result = func(theval);
    // ...
}
Solution 
  • string sym(1, thestring[i]);
theval = sym.c_str();

    It gives a null-terminated const char* for every character.
