Passing a reference to a function

I have a reference to a string, and I want to pass one character of that string to another function.

Basically, I have something like:

void func1(string *doc)
      if (func2(doc[i]))
            //do something

bool func2(char *chr)
      return true;

How do I correctly pass (*doc)[i] to func2?

func2(char *chr) takes argument of type char * i.e. pointer to char that is a string. So you need to pass as func2(doc). If you needed only on char in func2, it should be defined as

bool func2(char chr)
    return true;

and then your current call funcs(doc[i) would be correct.
